This manual provides information for programming and operating the Unit. Be sure to read this manual before attempting to use the Unit and keep this manual close at hand for reference during operation.

!WARNING It is extremely important that a PLC and all PLC Units be used for the speci-

fied purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PLC System to the above-mentioned applications.

3 Safety Precautions

!WARNING The CPU Unit refreshes I/O even when the program is stopped (i.e., even in

PROGRAM mode). Confirm safety thoroughly in advance before changing the status of any part of memory allocated to I/O Units, Special I/O Units, or CPU Bus Units. Any changes to the data allocated to any Unit may result in unexpected operation of the loads connected to the Unit. Any of the following operation may result in changes to memory status.

• Transferring I/O memory data to the CPU Unit from a Programming Device.

• Changing present values in memory from a Programming Device.

• Force-setting/-resetting bits from a Programming Device.

• Transferring I/O memory files from a Memory Card or EM file memory to the CPU Unit.

• Transferring I/O memory from a host computer or from another PLC on a network.

xxxviii

!WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing

so may result in electric shock.

Safety Precautions 3

!WARNING Do not touch any of the terminals or terminal blocks while the power is being

supplied. Doing so may result in electric shock.

!WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do

so may result in malfunction, fire, or electric shock.

!WARNING Do not touch the Power Supply Unit while power is being supplied or immedi-

ately after power has been turned OFF. Doing so may result in electric shock.

!WARNING Provide safety measures in external circuits (i.e., not in the Programmable

Controller), including the following items, to ensure safety in the system if an abnormality occurs due to malfunction of the PLC or another external factor affecting the PLC operation. Not doing so may result in serious accidents.

• Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits.

• The PLC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system.

• The PLC outputs may remain ON or OFF due to deposition or burning of the output relays or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.

• When the 24-V DC output (service power supply to the PLC) is overloaded or short-circuited, the voltage may drop and result in the outputs being turned OFF. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.

!Caution Confirm safety before transferring data files stored in the file memory (Mem-

ory Card or EM file memory) to the I/O area (CIO) of the CPU Unit using a Programming Device. Otherwise, the devices connected to the output unit may malfunction regardless of the operation mode of the CPU Unit.

!Caution Fail-safe measures must be taken by the customer to ensure safety in the

event of incorrect, missing, or abnormal signals caused by broken signal lines, momentary power interruptions, or other causes. Serious accidents may result from abnormal operation if proper measures are not provided.

!Caution Execute online edit only after confirming that no adverse effects will be

caused by extending the cycle time. Otherwise, the input signals may not be readable.

!Caution Confirm safety at the destination node before transferring a program to

another node or changing contents of the I/O memory area. Doing either of these without confirming safety may result in injury.

!Caution Tighten the screws on the terminal block of the AC Power Supply Unit to the

torque specified in the operation manual. The loose screws may result in burning or malfunction.

xxxix

Operating Environment Precautions 4

!Caution A CJ1-H or CJ1M CPU Unit automatically back up the user program and

parameter data to flash memory when these are written to the CPU Unit. I/O memory (including the DM, EM, and HR Areas), however, is not written to flash memory. The DM, EM, and HR Areas can be held during power interruptions with a battery. If there is a battery error, the contents of these areas may not be accurate after a power interruption. If the contents of the DM, EM, and HR Areas are used to control external outputs, prevent inappropriate outputs from being made whenever the Battery Error Flag (A40204) is ON. Areas such as the DM, EM, and HR Areas, the contents of which can be held during power interrupts, is backed up by a battery. If a battery error occurs, the contents of the areas that are set to be held may not be accurate even though a memory error will not occur to stop operation. If necessary for the safety of the system, take appropriate measures in the ladder program whenever the Battery Error Flag (A40204) turns ON, such as resetting the data in these areas.

!Caution When connecting a personal computers or other peripheral devices to a PLC

to which a non-insulated Power Supply Unit (CJ1W-PD022) is mounted, either ground the 0 V side of the external power supply or do not ground the external power supply at all ground. A short-circuit will occur in the external power supply if incorrect grounding methods are used. Never ground the 24 V side, as shown below.

4 Operating Environment Precautions

!Caution Do not operate the control system in the following locations:

• Locations subject to direct sunlight.

• Locations subject to temperatures or humidity outside the range specified in the specifications.

• Locations subject to condensation as the result of severe changes in temperature.

• Locations subject to corrosive or flammable gases.

• Locations subject to dust (especially iron dust) or salts.

• Locations subject to exposure to water, oil, or chemicals.

• Locations subject to shock or vibration.

0 V

!Caution Take appropriate and sufficient countermeasures when installing systems in

the following locations:

• Locations subject to static electricity or other forms of noise.

• Locations subject to strong electromagnetic fields.

• Locations subject to possible exposure to radioactivity.

• Locations close to power supplies.

Application Precautions 5

!Caution The operating environment of the PLC System can have a large effect on the

longevity and reliability of the system. Improper operating environments can lead to malfunction, failure, and other unforeseeable problems with the PLC System. Be sure that the operating environment is within the specified conditions at installation and remains within the specified conditions during the life of the system.

5 Application Precautions

Observe the following precautions when using the PLC System.

• You must use the CX-Programmer (programming software that runs on Windows) if you need to program more than one task. A Programming Console can be used to program only one cyclic task plus interrupt tasks. A Programming Console can, however, be used to edit multitask programs originally created with the CX-Programmer.

!WARNING Always heed these precautions. Failure to abide by the following precautions

could lead to serious or possibly fatal injury.

• Always connect to a ground of 100 connecting to a ground of 100

• A ground of 100 terminals on the Power Supply Unit.

• Always turn OFF the power supply to the PLC before attempting any of the following. Not turning OFF the power supply may result in malfunction or electric shock.

• Mounting or dismounting Power Supply Units, I/O Units, CPU Units, or any other Units.

• Assembling the Units.

• Setting DIP switches or rotary switches.

• Connecting cables or wiring the system.

• Connecting or disconnecting the connectors.

!Caution Failure to abide by the following precautions could lead to faulty operation of

the PLC or the system, or could damage the PLC or PLC Units. Always heed these precautions.

• A CJ-series CPU Unit is shipped with the battery installed and the time already set on the internal clock. It is not necessary to clear memory or set the clock before application, as it is for the CS-series CPU Units.

• The user program and parameter area data in CJ1-H/CJ1M CPU Units is backed up in the internal flash memory. The BKUP indicator will light on the front of the CPU Unit when the backup operation is in progress. Do not turn OFF the power supply to the CPU Unit when the BKUP indicator is lit. The data will not be backed up if power is turned OFF.

• If, when using a CJ-series CPU Unit, the PLC Setup is set to specify using the mode set on the Programming Console and a Programming Console is not connected, the CPU Unit will start in RUN mode. This is the default setting in the PLC Setup. (A CS1 CPU Unit will start in PROGRAM mode under the same conditions.)

Ω or less must be installed when shorting the GR and LG

Ω or less when installing the Units. Not

Ω or less may result in electric shock.

xli

Application Precautions 5

• When creating an AUTOEXEC.IOM file from a Programming Device (a Programming Console or the CX-Programmer) to automatically transfer data at startup, set the first write address to D20000 and be sure that the size of data written does not exceed the size of the DM Area. When the data file is read from the Memory Card at startup, data will be written in the CPU Unit starting at D20000 even if another address was set when the AUTOEXEC.IOM file was created. Also, if the DM Area is exceeded (which is possible when the CX-Programmer is used), the remaining data will be written to the EM Area.

• Always turn ON power to the PLC before turning ON power to the control system. If the PLC power supply is turned ON after the control power supply, temporary errors may result in control system signals because the output terminals on DC Output Units and other Units will momentarily turn ON when power is turned ON to the PLC.

• Fail-safe measures must be taken by the customer to ensure safety in the event that outputs from Output Units remain ON as a result of internal circuit failures, which can occur in relays, transistors, and other elements.

• Fail-safe measures must be taken by the customer to ensure safety in the event of incorrect, missing, or abnormal signals caused by broken signal lines, momentary power interruptions, or other causes.

• Interlock circuits, limit circuits, and similar safety measures in external circuits (i.e., not in the Programmable Controller) must be provided by the customer.

• Do not turn OFF the power supply to the PLC when data is being transferred. In particular, do not turn OFF the power supply when reading or writing a Memory Card. Also, do not remove the Memory Card when the BUSY indicator is lit. To remove a Memory Card, first press the memory card power supply switch and then wait for the BUSY indicator to go out before removing the Memory Card.

• If the I/O Hold Bit is turned ON, the outputs from the PLC will not be turned OFF and will maintain their previous status when the PLC is switched from RUN or MONITOR mode to PROGRAM mode. Make sure that the external loads will not produce dangerous conditions when this occurs. (When operation stops for a fatal error, including those produced with the FALS(007) instruction, all outputs from Output Unit will be turned OFF and only the internal output status will be maintained.)

• The contents of the DM, EM, and HR Areas in the CPU Unit are backed up by a Battery. If the Battery voltage drops, this data may be lost. Provide countermeasures in the program using the Battery Error Flag (A40204) to re-initialize data or take other actions if the Battery voltage drops.

• Always use the power supply voltages specified in the operation manuals. An incorrect voltage may result in malfunction or burning.

• Take appropriate measures to ensure that the specified power with the rated voltage and frequency is supplied. Be particularly careful in places where the power supply is unstable. An incorrect power supply may result in malfunction.

• Install external breakers and take other safety measures against short-circuiting in external wiring. Insufficient safety measures against short-circuiting may result in burning.

• Install Units as far as possible away from devices that generate strong, high-frequency noise.

• Do not apply voltages to the Input Units in excess of the rated input voltage. Excess voltages may result in burning.

xlii

Application Precautions 5

• Do not apply voltages or connect loads to the Output Units in excess of the maximum switching capacity. Excess voltage or loads may result in burning.

• Separate the line ground terminal (LG) from the functional ground terminal (GR) on the Power Supply Unit before performing withstand voltage tests or insulation resistance tests. Not doing so may result in burning.

• Change the applied voltage gradually using the adjuster on the Tester. If full dielectric strength voltage is applied or turned OFF using the switch on the Tester, the generated impulse voltage may damage the Power Supply Unit.

• Install the Units properly as specified in the operation manuals. Improper installation of the Units may result in malfunction.

• Do not apply a force greater than 100 N on the terminal block when tightening the terminals.

• Do not drop the product or subject it to excessive vibration or shock.

• Be sure that all the terminal screws, and cable connector screws are tightened to the torque specified in the relevant manuals. Incorrect tightening torque may result in malfunction.

• Leave the label attached to the Unit when wiring. Removing the label may result in malfunction if foreign matter enters the Unit.

• Remove the label after the completion of wiring to ensure proper heat dissipation. Leaving the label attached may result in malfunction.

• Use crimp terminals for wiring. Do not connect bare stranded wires directly to terminals. Connection of bare stranded wires may result in burning.

• Wire all connections correctly.

• Double-check all wiring and switch settings before turning ON the power supply. Incorrect wiring may result in burning.

• Mount Units only after checking terminal blocks and connectors completely.

• Be sure that the terminal blocks, Memory Units, expansion cables, and other items with locking devices are properly locked into place. Improper locking may result in malfunction.

• Check switch settings, the contents of the DM Area, and other preparations before starting operation. Starting operation without the proper settings or data may result in an unexpected operation.

• Check the user program for proper execution before actually running it on the Unit. Not checking the program may result in an unexpected operation.

• Confirm that no adverse effect will occur in the system before attempting any of the following. Not doing so may result in an unexpected operation.

• Changing the operating mode of the PLC (including the setting of the startup operating mode).

• Force-setting/force-resetting any bit in memory.

• Changing the present value of any word or any set value in memory.

• Resume operation only after transferring to the new CPU Unit the contents of the DM Area, HR Area, and other data required for resuming operation. Not doing so may result in an unexpected operation.

• Do not pull on the cables or bend the cables beyond their natural limit. Doing either of these may break the cables.

xliii

Application Precautions 5

• Do not place objects on top of the cables or other wiring lines. Doing so may break the cables.

• Do not use commercially available RS-232C personal computer cables. Always use the special cables listed in this manual or make cables according to manual specifications. Using commercially available cables may damage the external devices or CPU Unit.

• Do not connect pin 6 (+5 V power supply line) of the RS-232C port on the CPU Unit to any external device except the CJ1W-CIF11 RS-422A Adapter or NT-AL001 RS-232C/RS-422A Adapter. Doing so may damage the external device or CPU Unit.

• When replacing parts, be sure to confirm that the rating of a new part is correct. Not doing so may result in malfunction or burning.

• Before touching a Unit, be sure to first touch a grounded metallic object in order to discharge any static build-up. Not doing so may result in malfunction or damage.

• When transporting or storing circuit boards, cover them in antistatic material to protect them from static electricity and maintain the proper storage temperature.

• Do not touch circuit boards or the components mounted to them with your bare hands. There are sharp leads and other parts on the boards that may cause injury if handled improperly.

• Do not short the battery terminals or charge, disassemble, heat, or incinerate the battery. Do not subject the battery to strong shocks. Doing any of these may result in leakage, rupture, heat generation, or ignition of the battery. Dispose of any battery that has been dropped on the floor or otherwise subjected to excessive shock. Batteries that have been subjected to shock may leak if they are used.

• UL standards required that batteries be replaced only by experienced technicians. Do not allow unqualified persons to replace batteries.

• Dispose of the product and batteries according to local ordinances as they apply. Have qualified specialists properly dispose of used batteries as industrial waste.

xliv

• After connecting Power Supply Units, CPU Units, I/O Units, Special I/O Units, or CPU Bus Units together, secure the Units by sliding the sliders at the top and bottom of the Units until they click into place. Correct operation may not be possible if the Units are not securely properly. Be sure to attach the end cover provided with the CPU Unit to the rightmost Unit. CJseries PLCs will not operate properly if the end cover is not attached.

• Unexpected operation may result if inappropriate data link tables or parameters are set. Even if appropriate data link tables and parameters have been set, confirm that the controlled system will not be adversely affected before starting or stopping data links.

• CPU Bus Units will be restarted when routing tables are transferred from a Programming Device to the CPU Unit. Restarting these Units is required to read and enable the new routing tables. Confirm that the system will not be adversely affected before allowing the CPU Bus Units to be reset.

• When wiring crossovers between terminals, the total current for both terminals will flow in the line. Check the current capacities of all wires before wiring crossovers.

Conformance to EC Directives 6

• When wiring crossovers between terminals, the total current for both terminals will flow in the line. Check the current capacities of all wires before wiring crossovers.

• The following precautions apply to Power Supply Units with Replacement Notification.

• When the LED display on the front of the Power Supply Unit starts to alternately display “0.0” and “A02” or the alarm output automatically turns OFF, replace the Power Supply Unit within 6 months.

• Separate the alarm output cables from power lines and high-voltage lines.

• Do not apply a voltage or connect a load to the alarm output that exceeds the rated voltage or load.

• Maintain an ambient storage temperature of of 25% to 70% when storing the product for longer than 3 months to keep the replacement notification function in optimum working condition.

• Always use the standard installation method. A nonstandard installation will decrease heat dissipation, delay the replacement notification signal, and may degrade or damage the internal elements.

• Design the system so that the power supply capacity of the Power Supply Unit is not exceeded.

• Do not touch the terminals on the Power Supply Unit immediately after turning OFF the power supply. Electric shock may occur due to the residual voltage.

6 Conformance to EC Directives

6-1 Applicable Directives

•EMC Directives

• Low Voltage Directive

6-2 Concepts

EMC Directives

OMRON devices that comply with EC Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards (see the following note). Whether the products conform to the standards in the system used by the customer, however, must be checked by the customer.

EMC-related performance of the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring, and other conditions of the equipment or control panel on which the OMRON devices are installed. The customer must, therefore, perform the final check to confirm that devices and the overall machine conform to EMC standards.

Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:

EMS (Electromagnetic Susceptibility): EN61000-6-2 EMI (Electromagnetic Interference): EN61000-6-4

(Radiated emission: 10-m regulations)

xlv

Conformance to EC Directives 6

Low Voltage Directive

Always ensure that devices operating at voltages of 50 to 1,000 V AC and 75 to 1,500 V DC meet the required safety standards for the PLC (EN61131-2).

6-3 Conformance to EC Directives

The CJ-series PLCs comply with EC Directives. To ensure that the machine or device in which the CJ-series PLC is used complies with EC Directives, the PLC must be installed as follows:

1,2,3... 1. The CJ-series PLC must be installed within a control panel.

2. You must use reinforced insulation or double insulation for the DC power supplies used for the communications power supply and I/O power supplies.

3. CJ-series PLCs complying with EC Directives also conform to the Common Emission Standard (EN61000-6-4). Radiated emission characteristics (10-m regulations) may vary depending on the configuration of the control panel used, other devices connected to the control panel, wiring, and other conditions. You must therefore confirm that the overall machine or equipment complies with EC Directives.

6-4 Relay Output Noise Reduction Methods

Countermeasures

The CJ-series PLCs conforms to the Common Emission Standards (EN61000-6-4) of the EMC Directives. However, noise generated by relay output switching may not satisfy these Standards. In such a case, a noise filter must be connected to the load side or other appropriate countermeasures must be provided external to the PLC.

Countermeasures taken to satisfy the standards vary depending on the devices on the load side, wiring, configuration of machines, etc. Following are examples of countermeasures for reducing the generated noise.

(Refer to EN61000-6-4 for more details.) Countermeasures are not required if the frequency of load switching for the

whole system with the PLC included is less than 5 times per minute. Countermeasures are required if the frequency of load switching for the whole

system with the PLC included is more than 5 times per minute.

resistance of the inductive load. This time lag, between the moment the

circuit is opened and the moment the load is reset, caused by this method is longer than that caused by the CR method.

Yes Yes The varistor method prevents the impo-

sition of high voltage between the contacts by using the constant voltage characteristic of the varistor. There is time lag between the moment the cir-

cuit is opened and the moment the load is reset.

If the supply voltage is 24 or 48 V, insert the varistor in parallel with the load. If the supply voltage is 100 to 200 V, insert the varistor between the contacts.

The capacitance of the capacitor must be 1 to 0.5 µF per contact current of 1 A and resistance of the resistor must be 0.5 to 1 Ω per contact voltage of 1 V. These values, however, vary with the load and the characteristics of the relay. Decide these values from experiments, and take into consideration that the capacitance suppresses spark discharge when the contacts are separated and the resistance limits the current that flows into the load when the circuit is closed again.

The dielectric strength of the capacitor must be 200 to 300 V. If the circuit is an AC circuit, use a capacitor with no polarity.

The reversed dielectric strength value of the diode must be at least 10 times as large as the circuit voltage value. The forward current of the diode must be the same as or larger than the load current.

The reversed dielectric strength value of the diode may be two to three times larger than the supply voltage if the surge protector is applied to electronic circuits with low circuit voltages.

CJ-series Features Section 1-2

The CJ-series PLCs support the same task-based programming structure, instructions, high-speed instruction execution, I/O memory, functionality, and message communications as the CS-series PLCs. The main differences of the CJ-series in comparison to the CS-series PLCs are as follows (refer to page 67 for details):

• No Backplanes are required.

• Screw mounting is not supported (only DIN Track mounting).

• Smaller size (30% to 35% in terms of volume).

• Inner Boards are not supported.

• I/O interrupt tasks and external interrupt tasks are not supported by CJ1 CPU Units. (They are supported by CJ1-H CPU Units.)

• C200H Special I/O Units are not supported (e.g., SYSMAC BUS Remote I/O Units).

• It is not necessary to create I/O tables unless desired, i.e., I/O tables can be created automatically when power is turned ON.

• The startup mode when a Programming Console is not connected is RUN mode (rather than PROGRAM mode, as it is for CS1 CPU Units).

• Only version 2.04 or higher versions of CX-Programmer can be connected for CJ1 CPU Units, version 2.1 or higher for CJ1-H CPU Units, and version 3.0 or higher for CJ1M CPU Units.

Mount to DIN Track The CJ-series PLCs can be mounted to DIN Track along with power supplies

Faster Instruction Execution and Peripheral Servicing

At 90 x 65 mm (height x depth), the CJ-series Units have on 70% the height and half the depth of CS-series Units, contributing to machine downsizing.

Ample Programming Capacity

Processing for overhead, I/O refreshes, and peripheral servicing is also much faster.

With up to 250 Ksteps of program capacity, 256 Kwords of DM Memory, and 2,560 I/O points, there is sufficient capacity for added-value programs including machine interfaces, communications, data processing, etc.

CJ-series Features Section 1-2

Program and PLC Setup Compatibility with CSseries CPU Units

No Backplanes for Greater Space Efficiency

Up to 3 Expansion Racks and 40 Units

Two I/O Allocation Methods

There is almost 100% compatibility with CS-series CPU Units for programming and internal settings (PLC Setup).

Note Because of physical differences in the CJ-series PLCs, they do not

support all of the features of the CS-series PLC.

A flexible system configuration that requires less space is made possible because Backplanes are not required for CJ-series PLCs.

By connecting an I/O Control Unit to the CPU Rack and I/O Interface Units to Expansion Racks, up to three Expansion Racks (but only one for CJ1M CPU Units) can be connected. The CPU Rack can contain up to 10 Units, as can each of the three Expansion Racks, enabling a total of up to 40 Units.

The need for Backplanes was eliminated, enabling the following two methods for allocating I/O.

1. Automatic I/O Allocation at Startup I/O is allocated to the connected Units each time the power is turned ON (same as CQM1H PLCs).

2. User-set I/O Allocation If desired, the user can set I/O tables in the same way as for the CS-series PLCs.

The default setting is for automatic I/O allocation at startup, but the user can set the PLC to automatically use I/O tables to enable checking for Unit connection errors or to allocate unused words.

Allocate Unused Words The CX-Programmer can be used to allocate unused words in I/O tables for

transfer to the CPU Unit. This enables keeping words unallocated for future use or to enable system standardization/modularization.

Structured Programming

Division of the Program into Tasks

When the program is divided into tasks that handle separate functions, control systems, or processes, several programmers can develop these separate tasks simultaneously.

There can be up to 32 normal (cyclic) tasks and 256 interrupt tasks. There are four types of interrupts: the Power OFF Interrupt, Scheduled Interrupts, I/O Interrupts, and External Interrupts (interrupts from Special I/O Units or CPU Bus Units).

Task

When a new program is being created, standard programs can be combined as tasks to create an entire program.

Task 3 (D)

Using Symbols Arbitrary symbols (names up to 32 characters) that are independent of I/O ter-

minal allocations can be used in programming. Standard programs created with symbols are more general and easier to reuse as tasks in different programs.

Symbols specified for bit address:

SW1 VALVE

Global and Local Symbols Supported

I/O names are handled as symbols which can be defined as global symbols, which apply to all of the programs in all tasks, or as local symbols, which apply to just the local task.

When the symbols are defined, you can choose to have the local symbols allocated to addresses automatically.

Improve Overall System Response Performance

The response performance of the system can be improved by dividing the program into a system-management task and tasks used for control, and executing only those control tasks that need to be executed.

Simplify Program Modification

• Debugging is more efficient when the job of modifying and debugging the tasks can be divided among several individuals.

• Program maintenance is easier because only the tasks affected by changes have to be modified when there are changes (such as changes in specifications).

• Several consecutive program lines can be modified with online editing.

• The amount the cycle time is extended during online editing has been reduced.

Change Program Arrangement Easily

When separate tasks have been programmed for different production models, the task control instructions can be used to switch the program quickly from production of one model to another.

Step Control and Block Programming

The step control and block programming instructions can be used to control repetitive processes that are difficult to program with ladder programming alone.

Comments Several types of comments can be added to the program to make it easier to

understand, including Rung comments, and I/O comments.

Section Function The section function can be used to make the program easier to visualize

(CX-Programmer version 2.0 or higher).

CJ-series Features Section 1-2

Port-specific Protocol Macros

Create Protocol Macros for All Ports

Protocol macros can be used to create versatile communications functions for any of the PLC’s communications ports. The communications functions can have host link, NT Link, or protocol macro configurations and can be directed to RS-232C and RS-422/485 ports on any of the Units.

All together, a CPU Unit can support a maximum of 32 ports.

Host Computer Programming Device

CPU Unit

Up to 32 ports are possible

Standard Serial Communications with External Devices

Messages can be transferred to and from standard serial devices with the protocol macro function (according to preset parameter settings). The protocol macro function supports processing options such as retries, timeout monitoring, and error checks.

Symbols that read and write data to the CPU Unit can be included in the communications frames, so data can be exchanged with the CPU Unit very easily.

OMRON components (such as Temperature Controllers, ID System Devices, Bar Code Readers, and Modems) can be connected to a Serial Communications Unit with the standard system protocol. It is also possible to change the settings if necessary.

Serial Communications Unit

Note The Serial Communications Unit must be purchased separately to take

advantage of this function.

Multilevel Network Configurations

1-2-2 Versatile Functions

Memory Card and File Management Functions

Transfer Data to and from Memory Cards

Convert EM Area Banks to File Memory (CJ1-H and CJ1 CPU Units Only)

Automatic File Transfer at Start-up

I/O Memory Files in CSV and Text Format

Data area data, program data, and PLC Setup data can be transferred as files between the Memory Card (compact flash memory) and a Programming Device, program instructions, a host computer, or via FINS commands.

I/O Memory, program, and parameter areas stored as files.

Part of the EM Area can be converted to file memory to provide file management capabilities without a Memory Card and with much faster access time than a Memory Card. (The EM Area can be very useful for storing data such as trend data as files.)

The PLC can be set up to transfer the program and/or PLC Setup files from the Memory Card when the PLC is turned ON. With this function, the Memory Card provides a flash-ROM transfer. This function can also be used to store and change PLC configurations quickly and easily.

It is now possible to save production results and other data (hexadecimal) from the CPU Unit I/O memory in a Memory Card in CSV or text format. The data can then be read and edited using personal computer spreadsheet software by means of a Memory Card Adapter.

It is possible to format files, delete, copy, change file names, create new directories, and perform similar operations on a Memory Card from the ladder program during PLC operation.

CJ-series Features Section 1-2

Program Replacement during Operation

It is now possible to replace the entire user program in the CPU Unit from the Memory Card during operation. In this way, it is possible to switch PLC operation without stopping the PLC.

Replacement

Easy Backups It is now possible to back up all data (user programs, parameters, and I/O

memory) to the Memory Card by pressing the Memory Card power supply switch. In this way, if a malfunction arises, it is possible to back up all data in the CPU Unit at the time without using a Programming Device.

Specialized Instructions Simplify Programming

Text String Instructions The text string instructions allow text processing to be performed easily from

the ladder program. These instructions simplify the processing required when creating messages for transmission or processing messages received from external devices with the protocol macro function.

Processing of text string data

External device with standard serial port

Loop Instructions The FOR(512), NEXT(513), and BREAK(514) instructions provide a very

powerful programming tool that takes up little program capacity.

Index Registers Sixteen Index Registers are provided for use as pointers in instructions. An

Index Register can be used to indirectly address any word in I/O memory. The CJ-series PLCs also support the auto-increment, auto-decrement, and offset functions.

The Index Registers can be a powerful tool for repetitive processing (loops) when combined with the auto-increment, auto-decrement, and offset functions. Index Registers can also be useful for table processing operations such as changing the order of characters in text strings.

Table Data Processing Instructions

Stack Instructions

A region of I/O memory can be defined as a stack region. Words in the stack are specified by a stack pointer for easy FIFO (first-in first-out) or LIFO (last-in first-out) data processing.

Stack region

Pointer

Range Instructions

These instructions operate on a specified range of words to find the maximum value or minimum value, search for a particular value, calculate the sum or FCS, or swap the contents of the leftmost and rightmost bytes in the words.

CJ-series Features Section 1-2

Range specified in the instruction

Data

Search, find maximum, find minimum, etc.

Record-table Instructions

Record-table instructions operate on specially defined data tables. The record table must be defined in advance with DIM(631), which declares the number of words in a record and the number of records in the table. Up to 16 record tables can be defined.

Record tables are useful when data is organized in records. As an example, if temperatures, pressures, or other set values for various models have been combined into a table, the record-table format makes it easy to store and read the set values for each model.

The SETR(635) can be used to store the first address of the desired record in an Index Register. Index Registers can then be used to simplify complicated processes such as changing the order of records in the record table, searching for data, or comparing data.

Record 2 Set values for model A

Troubleshooting Functions

Failure Diagnosis: FAL(006) and FALS(007)

Failure Point Detection: FPD(269)

The FAL(006) and FALS(007) can be used to generate a non-fatal or fatal error when the user-defined conditions are met. Records of these errors are stored in the error log just like system-generated errors.

Diagnoses a failure in an instruction block by monitoring the time between execution of FPD(269) and execution of a diagnostic output and finding which input is preventing an output from being turned ON.

Error Log Functions The error log contains the error code and time of occurrence for the most

recent 20 errors (user-defined or system-generated errors).

Maintenance Functions The CJ-series PLCs record information useful for maintenance, such as the

number of power interruptions and the total PLC ON time.

CJ-series Features Section 1-2

Other Functions

Data Trace Function The content of the specified word or bit in I/O memory can be stored in trace

memory by one of the following methods: scheduled sampling, cyclic sampling, or sampling at execution of TRSM(045).

Trace memory

Specified address in I/O memory

Fixed Cycle Time Function

A fixed (minimum) cycle time can be set to minimize variations in I/O response times.

I/O Refreshing Methods

I/O refreshing can be performed cyclically and immediately by programming the immediate-refreshing variation of the instruction.

PLC Setup Functions

PLC operation can be customized with PLC Setup settings, such as the maximum cycle time setting (watch cycle time) and the instruction error operation setting, which determines whether instruction processing errors and access errors are treated as non-fatal or fatal errors.

Binary Refreshing of Timer/Counter Instruction PVs

Present values of timer/counter instructions can now be refreshed in binary, in addition to the existing BCD capability. (Binary refreshing, however, can be specified with only CX-Programmer Ver. 3.0 and higher.) This allows the timer/ counter setting time to be expanded to a range of 0 to 65535 (from the existing 0 to 9,999). Also, results calculated by other instructions can be used as is for timer/counter set values.

Windows-based Support Software

The single-port multiple-access (SPMA) function can be used to program and monitor other CPU Bus Units on the same bus (CPU Rack or Expansion

The CJ1W-PA205C Power Supply Units with Replacement Notification provide six display levels using a 7-segment display on the front panel of the Unit to indicate the remaining service life of the Power Supply Unit. An alarm output also notifies when the estimated remaining service life drops to 6 months or shorter. This function enables Power Supply Unit replacement before the power supply reaches the end of its service life resulting in a system failure.

CJ1-H and CJ1M CPU Unit Features Section 1-3

1-3 CJ1-H and CJ1M CPU Unit Features

1-3-1 CJ1-H-R CPU Unit Features

The CJ1-H-R (high-speed) CPU Units (CJ1H-CPU@@H-R) have the following features.

The CJ1-H-R CPU Units are completely upwardly compatible from the CJ1HCPU@@H Units, and yet they are much faster overall.

Example 1: A program consisting of 30K steps of only basic instructions with 128 inputs and 128 outputs executes in 0.7 ms, or 1.43 times faster (1 ms for a CJ1-H CPU Unit).

Example 2: A program consisting of 30K steps of basic and special instructions in a 7:3 ratio with 128 inputs and 128 outputs executes in 0.9 ms, or 1.33 times faster (1.2 ms for a CJ1-H CPU Unit).

Example 3: A program consisting of 30K steps of basic, special, and floatingpoint math instructions in a 6:3:1 ratio with 128 inputs, 128 outputs, two Analog Input Units, and Two Position Control Units (4 axes) executes in 1.5 ms, or

5.4 times faster (8.1 ms for a CJ1-H CPU Unit).

High-speed Overhead Processing (Less Than Half of Previous Models)

Overhead processing time has been reduced from 0.3 to 0.13 ms.

High-speed I/O Refreshing (Less Than Half of Previous Models)

On average, the refresh time for Basic I/O Units and Special I/O Units has been cut in half or more.

Examples: 16-point Input Unit: Reduced from 3 Analog Input Unit: Reduced from 120

µs to 1.4 µs

µs to 50 µs

High-speed Interrupts (Approximately Three Times Faster Than Previous Models)

The software interrupt response time has been reduced from 124 µs to 40 µs.

Scheduled Interrupts Set in Increments of 0.1 ms

A setting unit 0.1 ms has been added for scheduled interrupts.

High-speed Timer Instructions (Ten Times Faster Than Previous Models)

Although high precision was provided for the previous 1-ms timer instruction,

0.1-ms and 0.01-ms timer instructions have been added.

High-speed Clock Pulses (More Than Five Times Faster Than Previous Models)

Clock pulses of 0.1 ms, 1 ms, and 0.01 s (see note) have been added to the previous pulses of 0.02 s, 0.1 s, 0.2 s, 1 s, and 1 min.

Note The 0.01 s Clock Pulse cannot be used with unit version 4.1 of the

CJ1-H-R CPU Units. The 0.01 s Clock Pulse can be used with all other unit versions.

High-speed Floating-point Math (Up to 70 Times Faster Than Previous Models

Floating-point calculations of sine, cosine, and tangent functions are up to 70 times faster than previous models. Example: SIN: 42.0 reduced to 0.59 times faster).

µs reduced to 0.59 µs (71 times faster), COS: 31.5 µs

µs (53 times faster), TAN: 16.3 µs reduced to 1.18 µs (13.8

CJ1-H and CJ1M CPU Unit Features Section 1-3

New Instruction Added

• High-speed Special I/O Unit refresh: FIORF(225)

More Relays in Relay Network Tables in Routing Tables

The number of relays that can be set in a relay network table has been increased from 20 to 64. Refer to the CX-Integrator Operation Manual (W445) and the Communication Unit operation manuals for details.

1-3-2 CJ1-H CPU Unit Features

Faster in Essentially Every Way

Ultra High-speed Cycle Time

1,2,3... 1. Instruction execution times: Only about 1/2 the time required for basic in-

The CJ1-H CPU Units provide a cycle time that is three to four times faster than that of the CJ1 CPU Units.

For example, a program consisting of 38 Ksteps of only basic instructions with 128 inputs and 128 outputs executes in 1 ms (4.9 ms for the CJ1 CPU Units); a program consisting of 20 Ksteps of basic and special instructions in a 1:1 ratio with 128 inputs and 128 outputs executes in 1 ms (2.7 ms for the CJ1 CPU Units); and a program consisting of 8 Ksteps of basic and special instructions in a 1:2 ratio with 64 inputs and 64 outputs executes in 0.5 ms (1.4 ms for the CJ1 CPU Units).

The following factors give the CJ1-H CPU Units their high speed.

structions, and only about 1/3 the time required for special instructions.

2. Better bus performance: Data transfers between the CPU Unit and Special I/O or Communications Units is about twice as fast, providing greater overall system performance.

3. Instruction execution is performed in parallel with peripheral servicing.

4. Other factors, including background execution of text string processing and table data processing instructions.

CJ1-H and CJ1M CPU Unit Features Section 1-3

Faster Execution of Common Instructions

System Bus Speed Doubled

Parallel Processing of Instructions and Peripheral Servicing

Extensive research on applications of CJ1 CPU Units was used to identify the 20 most commonly used instructions of the more than 400 supported instructions (see below), and execution speed for these instructions was increased by 10 to 20 times previous performance.

CPS (SIGNED BINARY COMPARE) JMP (JUMP) CPSL (DOUBLE SIGNED BINARY COMPARE) CJP (CONDITIONAL JUMP) XFER (BLOCK TRANSFER) BCNT (BIT COUNTER) MOVB (MOVE BIT) MLPX (DATA DECODER) MOVD (MOVE DIGITS) BCD (BINARY-TO-BCD) BSET (BLOCK SET) SBS/RET (SUBROUTINE CALL/RETURN)

The speed of transferring data between the CPU Unit and CPU Bus Units has been doubled to increase overall system performance.

A special mode is supported that enables parallel processing of instruction execution and peripheral device servicing to support the following types of application.

• Extensive data exchange with a host not restricted by the program capacity in the CJ1-H CPU Unit

• Consistently timed data exchange with SCADA software

• Eliminating the effects on cycle time of future system expansion or increases in communications

Less Cycle Time Fluctuation for Data Processing

Better Data Link and Remote I/O Refreshing

Immediate Refreshing for CPU Bus Units

Table data processing and text string processing, which often require time, can be separated over several cycles to minimize fluctuations in the cycle time and achieve stable I/O response.

CPU Bus Unit refresh response has been increased both by reductions in the cycle time itself and by the addition of an immediate I/O refresh instruction for CPU Bus Units (DLNK(226)). This instruction will refresh data links, DeviceNet remote I/O, protocol macros, and other special data for CPU Bus Units.

The response of a CJ1-H CPU Unit is approximately 2.4 times that of a CJ1 CPU Unit. And, for a cycle time of approximately 100 ms or higher, the increase in the data link response is comparable to that for the cycle time.

Although previously, I/O refreshing for CPU Bus Units was possible only after program executions, a CPU BUS I/O REFRESH instruction (DLNK(226)) has been added to enable immediate I/O refreshing for CPU Bus Units. Data links, DeviceNet remote I/O, an other unique CPU Bus Unit refreshing can be refreshed along with words allocated to the CPU Bus Unit in the CIO and DM Areas whenever DLNK(226) is executed. This is particularly effective for longer cycle times (e.g., 100 ms or longer). (Data exchange for data links, DeviceNet remote I/O, and other network communications are also affected by the communications cycle time, i.e., DLNK(226) refreshes data only between the CPU Bus Units and the CPU Unit, not the data on the individual networks.)

CJ1-H and CJ1M CPU Unit Features Section 1-3

Function Block (FB)

When using a CPU Unit with unit version 3.0 or later, standard processes can be encapsulated as easily reusable function blocks as long as those processes only exchange I/O data externally. The function blocks can be written in ladder language or ST (structured text) language. Mathematical processing that is difficult to write in ladder language can be written easily in the ST language.

OMRON function blocks can be written in ladder language or ST (structured text) language, and conform to IEC 61131-3 standards (JIS B3503). The function blocks provide functions for more efficient design and debugging of the user equipment, as well as easier maintenance.

Smart FB Library The Smart FB Library is a set of function blocks that improve interoperability

between OMRON PLC Units and FA components. Since it isn't necessary to create a ladder program to use basic Unit and FA component functions, the user can concentrate on more important work, such as determining how to make the most of device functions.

Online Editing of FB Definitions

Nesting Not only can programs be created with nested OMRON FBs, it is possible to

Offline Debugging with the Simulator

Variable Support for String Operations (CPU Units with Unit Version 4.0 or Later)

FB Generation Function Existing PLC programming can be reused by easily converting it to FBs.

FB definitions can be changed during operation, so FB definitions can be edited quickly during debugging. In addition, FBs can be used with confidence even in equipment that must operate 24 hours/day. (Requires CPU Unit unit version 4.0 or later and CX-Programmer version 7.0 or higher.)

tion of the program by setting passwords for the function block definitions allocated in the project file and protecting the definitions based on their purpose. (Requires CX-Programmer version 6.1 or higher.)

The Simulator enables checking the PLC program's operation on the desktop, so program quality can be improved and verified early on. Both the ladder and ST programming can be executed in the computer application.

The functions that perform string data operations in ST language not only support string variables, they also strengthen the functions used to communicate with string data I/O. This feature simplifies the creation of programs that send and receive communications commands. (Requires CPU Unit unit version 4.0 or later and CX-Programmer version 7.0 or higher.)

(Requires CX-Programmer version 7.0 or higher.)

High-speed Structured Programming

To further aid standardized programming, program structuring functions have been improved, as has program execution speed.

Function Blocks Required programming can be “encapsulated” in function blocks using either

ladder diagrams or structure text. (Requires CPU Unit unit version 3.0 or later.)

More Cyclic Tasks Tasks provide better efficiency by enabling programs to be separated by func-

tion or for development by different engineers. The CJ1-H CPU Units support up to 288 cyclic tasks, an incredible increase over the previous maximum of 32 tasks.

CJ1-H and CJ1M CPU Unit Features Section 1-3

Common Processing from Multiple Tasks

Faster Subroutine Instructions

Shared Index and Data Registers between Tasks

Download/Upload Tasks Individually (Unit Version

2.0 or Later)

Global subroutines that can be called by any task are now supported. These can be used for common processing from more than one task, for greater standardization.

Subroutine instruction are executed approximately 9 or 17 times faster to enable greater program modularization without having to be concerned about increasing the cycle time.

Although separate index and data registers can still be used in each task, they have been joined by shared index and data registers that can be used between tasks to reduce the time required to switch between tasks.

The CX-Programmer can be used to upload or download only the required tasks. This enables the member of a development team to work separately and then upload/download tasks after debugging them, helping to eliminate the need for unification work by a manager as well as mistakes that can easily occur in such work.

Battery-free Operation with Flash Memory

Any user program or parameter area data transferred to the CPU Unit is automatically backed up in flash memory in the CPU Unit to enable battery-free operation without using a Memory Card.

Note Refer to information on flash memory in the CS/CJ Series Programming Man-

ual (W394) for precautions on this function.

Store Comment/Section Data in CPU Unit’s Flash Memory (Unit Version 3.0 or Later)

The CX-Programmer can be used to save I/O comments and other comment/ section data in the comment memory contained in the CPU Unit’s flash memory. When the simple backup operation is used, the comment/section data in flash memory can also be backed up.

Many Protection Functions

Improved Read Protection Using Passwords with CXProgrammer Version 4.0 or Higher

Protection for CPU Units from FINS Write Commands Sent via Networks

Read Protection for Specific Tasks

Passwords can be set to read-protect individual groups of tasks. This enables creating black boxes in the program.

Enabling/Disabling Creating File Memory Program Files

When read protection is set, an optional setting allows you to enable or disable creating program backup files (.OBJ). This setting can be used to prevent programs from being disclosed.

Program Write Protection

The user program can be protected without using the DIP switch setting. This helps prohibit unauthorized or accidental program changes.

Write operations to a CPU Unit using FINS commands across networks can be enabled for specific nodes and disabled for all other nodes. This can be used to enable monitoring data via networks while eliminating the possibility of accidental mistakes caused by careless writing operations.

More Instructions for Specific Applications

Very specific control can be easily programmed for a much wider range of applications with the many new special instructions added to the CJ1-H CPU Units.

High-speed Positioning for XY Tables

Double-precision floating-point calculations are supported for the CJ1-H CPU Units to provide even better precision for position control operations.

CJ1-H and CJ1M CPU Unit Features Section 1-3

Convert between Floating Point and Text String Data

Accurate Line Approximations

Realtime Workpiece Data Management

PID Autotuning Autotuning is now supported for PID constants with the PID CONTROL

System Debugging through Error Simulation

Program Simplification with More Specific Basic Instructions

To display floating-point data on PTs, the CJ1-H CPU Units provide conversion instructions from floating-point data to text strings (ASCII). Conversion between ASCII and floating-point data is also possible so that ASCII data from serial communications with measurement devices can be used in calculations.

Unsigned 16-bit binary/BCD data, signed 16/32-bit binary data, or floatingpoint data can be used for line data, enabling precise (high data resolution) conversions, such as from a level meter (mm) to tank capacity (l) based on the shape of the tank.

When loading and unloading workpieces from conveyor lines, stack instructions can be used to manage workpiece information in realtime in table format.

instruction. The limit cycle method is used to ensure rapid autotuning. Very effective for multiloop PID control.

A specified error status can be created with the FAL/FALS instructions. This can be used effectively when depending systems. For example, errors can be simulated to produce corresponding displays on a PT to confirm that the correct messages are being displayed.

Programs that use a high quantity of basic instructions can be simplified though the use of differentiated forms of the LD NOT, AND NOT and OR NOT instructions, and through the use of OUT, SET, and RSET instructions that can manipulate individual bits in the DM or EM Area.

Delayed Power OFF Processing for Specified Program Areas

Multiple Interlock Instructions (MILH(517), MILR(518), and MILC(519)) for Nested Interlocks

TIME-PROPORTIONAL OUTPUT (TPO(685)) Instruction for Time-proportional Operation with Temperature Controllers or Variable-duty Lighting/ Power Control

Symbol Time Comparison Instructions for Easy Calendar Timers

The DI and EI instructions can be used to disable interrupts during specific portions of the program, for example, to prevent the power OFF interrupt from being executed until a specific instruction has been executed.

These instruction enable easy creation of nested interlocks. For example, create one interlock to control the entire program (e.g., for an emergency stop) and then nest other interlocks for separate portions of the program (e.g., conveyor operation, alarms, etc.).

This instruction is used in combination with PID instructions to create a timeproportional output based on the manipulated variable output by the PID instruction. This enables easily connecting an SSR to a Transistor Output Unit to achieve time-proportional operation of a Temperature Controller. Variableduty pulse outputs can also be created for lighting or power control.

Two times/dates can be compared to continue operation to the next instruction in the ladder program rung when the results of comparison is true. Opposed to normal comparison instructions, comparisons are by byte and the bytes that are compared in the time/date data can be controlled. This enables comparing built-in clock data with set times/dates to easily create a calendar timer, for example, on the hour (when the minutes is 0) or on a specific date each year).

CJ1-H and CJ1M CPU Unit Features Section 1-3

GRAY CODE CONVERSION (GRY(474)) for Easy Conversion of Parallel Inputs from Absolute Encoders to Binary, BCD, or Angle Data

EXPANDED BLOCK COMPARE (BCMP2(502)) for Comparison Judgements for Up to 256 Ranges (Upper/Lower Limits) with One Instruction

Easier Processing of I/O Devices with Special I/O Instructions

This instruction converts Gray binary codes to binary, BCD, or angle data. This enables easily handling position or angle data input as parallel signals

) from an Absolute Encoder with a Gray code output using a DC Input Unit.

This instruction determines if a value is within any of up to 256 ranges defined by upper and lower limits. When used with the GRAY CODE CONVERSION (GRY(474)) instruction, the same operation as a cam switch can be achieved by determining if an angle input from an Absolute Encoder is in a comparison table.

Previously many instructions were required to read or write data for external input devices such as digital switches and 7-segment displays connected to Basic I/O Units. Now, I/O processing for these devices can be achieved with a single instruction. These are sometimes call Combination Instructions.

These instructions are the same as those supported by the C200HX/HG/HE and CQM1H PLCs, with the exception that more than one of each of these instructions can be executed in a single user program.

TEN KEY INPUT (TKY(211))

Sequentially reads numbers input from a ten-key connected to an Input Unit.

HEXADECIMAL KEY INPUT (HKY(212))

Sequentially reads numbers input from a hexadecimal keypad connected to an Input Unit and an Output Unit for a maximum of 8 digits.

DIGITAL SWITCH INPUT (DSW(213))

Reads numbers input from a digital switch or thumbwheel switch connected to an Input Unit and an Output Unit. Either 4 or 8 digits are read.

MATRIX INPUT (MTR(210))

Sequentially reads 64 input points input from a 8 x 8 matrix connected to an Input Unit and an Output Unit.

7-SEGMENT DISPLAY OUTPUT (7SEG(214))

Converts 4-digit or 8-digit values to data for a 7-segment display and outputs the result.

Read/Write CPU Bus Unit Memory Areas with IORD(222)/IOWR(223)

Although INTELLIGENT I/O READ (IORD(222)) and INTELLIGENT I/O WRITE (IOWR(223)) could previously be used only for Special I/O Units, these instructions can now be used to read and write data for CPU Bus Units.

Easier Network Connections and More-advanced Seamless Network Communications

Online Connections via Networks without I/O Tables

Online connection is possible to any PLC in the local network from a Programming Device, such as the CX-Programmer, as soon as the network is connected. It’s not necessary to create the I/O tables to enable connection; automatic I/O allocation at startup is used. This eliminates the need to use a serial connection to create I/O tables before the CX-Programmer can be connected via Ethernet. Only an Ethernet connection through a CJ1W-ETN21 Ethernet Unit is required to go online and create I/O tables.

Work Across Up to Eight Networks with CX-Net in CX-Programmer Version

4.0 or Higher

FINS commands can be sent across up to 8 network levels (including the local network). This enables a wider range of communications between devices on Ethernet and Controller Link Networks.

CJ1-H and CJ1M CPU Unit Features Section 1-3

FINS commands can only be sent across up to 8 network levels when the destination is a CPU Unit. FINS commands can be sent to other destinations up to 3 network levels away.

Online Connections to PLCs via NS-series PTs

Easier Implementation of Explicit Messages with Explicit Message Instructions

Downloading, uploading, and monitoring of ladder programs or other data is possible to a PLC connected serially to an NS-series PT from the CX-Programmer connected to the NS-series PT by Ethernet.

Special Explicit Message Instructions are now supported to simplify using explicit messages. (Previously, CMND(490) had to be used to send a FINS command of 2801 hex to enable sending explicit messages.) The new instructions include the following: EXPLICIT MESSAGE SEND (EXPLT(720)), EXPLICIT GET ATTRIBUTE (EGATR(721)), EXPLICIT SET ATTRIBUTE (ESATR(722)), EXPLICIT WORD READ (ECHRD(723)), and EXPLICIT WORD WRITE (ECHWR(724)). Of these, EXPLICIT WORD READ (ECHRD(723)) and EXPLICIT WORD WRITE (ECHWR(724)) enable easily reading and writing data in CPU Units on networks with the same type of notation as used for SEND(290) and RECV(298). (Does not apply to C200HX/ HG/HE and CV-series PLCs.)

Incorporate CompoWay/F-compatible OMRON Components into FINS Network Via Serial Gateway

Using the Serial Gateway mode for the CPU Unit’s serial port enables flexible access to CompoWay/F-compatible OMRON components from devices on the network (e.g., PTs, PLC CPU Units, personal computers).

Use No-protocol Communications at Multiple Ports

No-protocol communications can be performed via the serial ports of Serial Communications Boards/Units with unit version 1.2 or later. This enables noprotocol communications at multiple ports.

Greater Flexibility in I/O Allocations

First Word Address Settings for Slots (Using CX-Programmer Version

3.1 or Higher)

When editing I/O tables for CJ1-H/CJ1M CPU Units, the first word address can be set for up to 64 slots. This can be used, for example, to create fixed starting addresses for Input Units and Output Unit to separate I/O allocations from the program and increase the efficiency of program maintenance.

Automatic Transfer at Power ON

Automatic Transfers at Power ON without a Parameter File (.STD)

Automatic Detection of I/O Allocation Method for Automatic Transfer at Power ON (CJ1-H and CJ1M CPU Units Ver. 2.0 or Later)

The user program can be automatically transferred to the CPU Unit at power ON without a parameter file (.STD) if the name of the program file (.OBJ) is changed to REPLACE on the CX-Programmer and the file is stored on a Memory Card. This can be used, for example, to enable transferring a program to a CPU Unit by creating the program offline and sending it as an email attachment, without a local Programming Device.

The method used to create the parameter file (AUTOEXEC.STD) for automatic transfer at power ON (automatic I/O allocation at startup or user-set I/O allocation) is recorded. When an automatic transfer at power ON is executed from the Memory Card, the recorded method is automatically detected and used to create the I/O tables.

For example, this method can be used to create files for automatic transfer at power ON in an office where Units are not mounted yet. The files can be stored in a Memory Card, which can then be taken and installed in a CJseries CPU Unit at the remote site. When automatic transfer at power ON is

CJ1-H and CJ1M CPU Unit Features Section 1-3

executed, the I/O will be allocated by the CPU Unit according to the method recorded in the Memory Card.

Operation Start/End Times

The times that operation is started and ended are automatically stored in memory in the Auxiliary Area (A515 to A517). This enables easier management of the operating times of the PLC System.

Free-running Timers

The system timers used after the power is turned ON are contained in the following Auxiliary Area words.

Name Address Function Access

10-ms Incrementing Free Running Timer

100-ms Incrementing Free Running Timer

1-s Incrementing Free Running Timer

Better Compatibility with Other SYSMAC PLCs

C200HE/HG/HX PLCs The AREA RANGE COMPARE (ZCP) and DOUBLE AREA RANGE COM-

PARE (ZCPL) instructions are supported in the CJ1-H CPU Units to provide better compatibility with the C200HE/HG/HX PLCs.

CVM1/CV-series PLCs The CONVERT ADDRESS FROM CV instruction allows real I/O memory

addresses for the CVM1/CV-series PLCs to be converted to addresses for the CJ-series PLCs, enabling programs with CVM1/CV-series addresses to be quickly converted for use with a CJ-series CPU Unit.

1-3-3 CJ1M CPU Unit Features

Built-in I/O

The CJ1M CPU Units are high-speed, advanced, micro-sized PLCs equipped with built-in I/O. The built-in I/O have the following features.

General-purpose I/O Immediate Refreshing

The CPU Unit's built-in inputs and outputs can be used as general-purpose inputs and outputs. In particular, immediate I/O refreshing can be performed on the I/O in the middle of a PLC cycle when a relevant instruction is executed.

Stabilizing Input Filter Function

The input time constant for the CPU Unit's 10 built-in inputs can be set to 0 ms (no filter), 0.5 ms, 1 ms, 2 ms, 4 ms, 8 ms, 16 ms, or 32 ms. Chattering and the effects of external noise can be reduced by increasing the input time constant.

Interrupt Inputs High-speed Interrupt Input Processing

The CPU Unit's 4 built-in inputs can be used for high-speed processing as regular interrupt inputs in direct mode or interrupt inputs in counter mode. An interrupt task can be started at the interrupt input's rising or falling edge (up or down differentiation.) In counter mode, the interrupt task can be started when the input count reaches the set value (up-differentiated or down-differentiated transitions.)

High-speed Counters High-speed Counter Function

A rotary encoder can be connected to a built-in input to accept high-speed counter inputs.

Trigger Interrupts at a Target Value or in a Specified Range

Interrupts can be triggered when the high-speed counter’s PV matches a target value or is within a specified range.

Measure the Frequency of High-speed Counter Inputs

The PRV(881) instruction can be used to measure the input pulse frequency (one input only.)

Maintain or Refresh (Selectable) High-speed Counter PVs

The High-speed Counter Gate Bit can be turned ON/OFF from the ladder program to select whether the high-speed counter PVs will be maintained or refreshed.

Pulse Outputs Fixed duty ratio pulses can be output from the CPU Unit's built-in outputs to

perform positioning or speed control with a servo driver that accepts pulse inputs.

CJ1-H and CJ1M CPU Unit Features Section 1-3

CW/CCW Pulse Outputs or Pulse + Direction Outputs

The pulse output mode can be set to match the motor driver's pulse input specifications.

Automatic Direction Selection for Easy Positioning with Absolute Coordinates

When operating in absolute coordinates (origin defined or PV changed with the INI(880) instruction), the CW/CCW direction will be selected automatically when the pulse output instruction is executed. (The CW/CCW direction is selected by determining whether the number of pulses specified in the instruction is greater than or less than the pulse output PV.)

Triangular Control

Triangular control (trapezoidal control without a constant-speed plateau) will be performed during positioning executed by an ACC(888) instruction (independent) or PLS2(887) instruction if the number of output pulses required for acceleration/deceleration exceeds the specified target pulse Output Amount. Previously, an error would have occurred under these conditions and the instruction would not have been executed.

Change Target Position during Positioning (Multiple Start)

When positioning was started with a PULSE OUTPUT (PLS2(887)) instruction and the positioning operation is still in progress, another PLS2(887) instruction can be executed to change the target position, target speed, acceleration rate, and deceleration rate.

Switch from Speed Control to Positioning (Fixed Distance Feed Interrupt)

A PLS2(887) instruction can be executed during a speed control operation to change to positioning mode. This feature allows a fixed distance feed interrupt (moving a specified amount) to be executed when specific conditions occur.

Change Target Speed and Acceleration/Deceleration Rate during Acceleration or Deceleration

When trapezoidal acceleration/deceleration is being executed according to a pulse output instruction (speed control or positioning), the target speed and acceleration/deceleration rate can be changed during acceleration or deceleration.

Use Variable Duty Ratio Pulse Outputs for Lighting, Power Control, Etc.

The PULSE WITH VARIABLE DUTY RATIO instruction (PWM(891)) can be used to output variable duty ratio pulses from the CPU Unit's built-in outputs for applications such as lighting and power control.

Origin Search Use a Single Instruction for Origin Search and Origin Return Operations

A precise origin search can be executed with one instruction that uses various I/O signals, such as the Origin Proximity Input Signal, Origin Input Signal, Positioning Completed Signal, and Error Counter Reset Output.

Also, an origin return operation can be performed to move directly to the established origin.

Quick-response Inputs Receive Input Signals Shorter than the Cycle Time

With quick-response inputs, inputs to the CPU Unit's built-in inputs (4 inputs max.) with an input signal width as short as 30 regardless of the cycle time.

µs can be received reliably

CJ1-H and CJ1M CPU Unit Features Section 1-3

Improved Functions for PRV(881) and PRV2(883) (CJ1M Only)

Pulse Frequency Conversions

High-frequency calculation methods have been added to the pulse frequency calculation methods for PRV(881) (HIGH-SPEED COUNTER PV READ) and PRV2(883) (PULSE FREQUENCY CONVERT) instructions (minimizes the error in high frequencies of 1 kHz or higher). PRV(881) can also be used to read the pulse output frequency.

The pulse frequency input to high-speed counter 0 can be converted to a rotational speed (r/min.) or the PV of the counter can be converted to the total number of rotations.

Serial PLC Link Function

Data links (9 max.) can be set up between PLCs using the CPU Unit’s RS232C port. NT Link (1:N connection) can also be incorporated in a Serial PLC Link network, allowing the existing NT Link (1:N mode) and the Serial PLC Link to be used together.

Note 1: PTs are included in the number of links. Note 2: The Serial PLC Link cannot be used for PT data links.

Scheduled Interrupt Function Used as High-precision Timer

Scheduled interrupts in units of 0.1 ms have been added for CJ1M CPU Units. An internal PV reset start function for scheduled interrupts has also been added, so it is possible to standardize the time to the first interrupt without using the CLI instruction. It is also possible to read the elapsed time from either a scheduled interrupt start or from the previous interrupt. This allows the interval timer (STIM instruction) in the CQM1H Series to be easily used for the CJ Series.

1-5-1 Function Blocks (FB)

Unit Ver. 2.0 or Earlier Earlier Units did not support function blocks (FB).

Unit Ver. 3.0 or Later Function blocks (FB) conforming to IEC 61131-3 are supported. Use of func-

tion blocks is determined by the user.

Note IEC 61131-3 is an international standard for programmable logic

controllers (PLC) established by the International Electro-technical Commission (IEC). This standard is divided into seven parts, of which Part 3 Programming Languages (IEC 61131-3) provides regulations for programming PLCs.

Function blocks can be created with CX-Programmer Ver. 5.0 or higher by the user and pasted into normal programs. The standard function blocks provided by OMRON in the OMRON FB Library can also be pasted into normal programs. Function blocks enable standard processing to be simply inserted into a program as a single unit. Function blocks provide the following features.

• Function block algorithms can be written using ladder programming or structured text (see note).

Note Structured text is a high level textual language designed for industrial

control (primarily PLCs) stipulated in IEC 61131-3. The structured text supported by CX-Programmer Ver. 5.0 conforms to IEC 61131-1.

• A single function block that has been created can be stored in a library for easy reuse of standard processing.

• Programs that contain function blocks (ladder programming or structured text), can also be uploaded or downloaded in the same way as normal programs that do not contain function blocks. Tasks that include function blocks, however, cannot be downloaded in task units (although they can be uploaded).

• Array (one-dimensional) variables are supported, making it easier to handle data specific to an application.

1-5-2 Serial Gateway (Converting FINS to CompoWay/F Via Serial Port)

Unit Ver. 2.0 or Earlier Temperature Controllers, Digital Panel Meters, and other CompoWay/F-com-

patible OMRON Components previously could be accessed by sending userspecified CompoWay/F commands from the PLC. This required, however, the use of a Serial Communications Board/Unit protocol macro, execution of the PMCR(260) instruction in the ladder program of the CPU Unit on the same PLC, and implementation of the standard system protocol (CompoWay/F Master). The use of protocol macros prevented access across networks.

CJ1-H/CJ1M CPU Unit Ver. 3.0 Upgrades Section 1-5

Note Specific data could be shared without communications instructions if

user-specified CompoWay/F commands were not required, however, by using the CJ1W-CIF21 Basic Communications Unit.

Unit Ver. 3.0 or Later FINS commands (CompoWay/F commands encapsulated in FINS frames)

received by the CPU Unit at the built-in serial port (RS-232C port or peripheral port) are converted automatically into CompoWay/F command frames and transmitted on the serial line. This enables access to CompoWay/F-compatible OMRON components that are connected to the CPU Unit’s built-in serial port via either an NS-series Programmable Terminal (PT) or by using the CMND(490) instruction.

1-5-3 Comment Memory (in Internal Flash Memory)

Unit Ver. 2.0 or Earlier Comment data and section data could not be stored in the actual PLC when a

project was downloaded from the CX-Programmer to the CPU Unit unless both a Memory Card and EM file memory were available.

Unit Ver. 3.0 or Later A comment memory is provided within the CPU Unit’s internal flash memory.

Therefore, the following comment/section data can be stored in and read from comment memory even if neither Memory Card nor EM file memory are available.

• Symbol table files (including CX-Programmer symbol names and I/O comments)

• Comment files (CX-Programmer rung comments and other comments)

• Program index files (CX-Programmer section names, section comments, and program comments)

CX-Programmer Ver. 4.0 or Earlier

When using CX-Programmer Ver. 4.0 or earlier, data is stored in either the Memory Card or EM file memory, whichever is available. If neither the Memory Card nor EM file memory is available, the comment/section data is stored in comment memory (in CPU Unit’s internal flash memory).

1-5-4 Simple Backup Data Expanded

Unit Ver. 2.0 or Earlier The simple backup function could not be used to back up comment data or

section data.

Unit Ver. 3.0 or Later The following files stored in comment memory can be backed up to a Memory

Card when a simple backup operation is executed, or the files can be restored to comment memory from the Memory Card.

• Symbol table files (including CX-Programmer symbol names and I/O comments)

• Comment files (CX-Programmer rung comments and other comments)

• Program index files (CX-Programmer section names, section comments, and program comments)

Note The timer will continue to be incremented when the operating mode is

switched to RUN mode.

Example: The interval can be counted between processing A and processing

B without requiring timer instructions. This is achieved by calculating the difference between the value in A000 for processing A and the value in A000 for processing B. The interval is counted in 10 ms units. CPU Units with unit version 4.0 and later also have a 1-s timer in A002, which is incremented by 1 every 1 s.

1-5-6 New Special Instructions and Functions

The following new instructions and instruction functions have been added. For details, refer to the CS/CJ Series Instructions Reference Manual (W340). These new instructions are supported by the CX-Programmer Ver. 5.0 or higher only.

• Serial Communications Instructions: Supporting no-protocol communications with Serial Communications Units with unit version 1.2 or later: TXDU(256): TRANSMIT VIA SERIAL COMMUNICATIONS UNIT RXDU(255): RECEIVE VIA SERIAL COMMUNICATIONS UNIT Supporting no-protocol communications with Serial Communications Boards with unit version 1.2 or later: TXD(236): TRANSMIT RXD(235): RECEIVE

• Model Conversion Instructions: When using CX-Programmer Ver. 5.0 or higher to convert a C-series ladder program for use in a CS/CJ-series CPU Unit, the C-series XFER(070), DIST(080), COLL(081), MOVB(082), and BCNT(067) instructions will be automatically converted to the following instructions. The operands do not require editing. XFERC(565) BLOCK TRANSFER DISTC(566) SINGLE WORD DISTRIBUTE COLLC(567) DATA COLLECT MOVBC(568) MOVE BIT BCNTC(621) BIT COUNTER

• High-speed Counter/Pulse Output Instructions (CJ1M Only): High-frequency calculation methods have been added to the pulse frequency calculation methods for PRV(881) (HIGH-SPEED COUNTER PV READ) and PRV2(883) (PULSE FREQUENCY CONVERT) instructions. PRV(881) can also be used to read the pulse output frequency.

Previous CPU Units (Pre-Ver. 2.0 CPU Units)

With the Pre-Ver. 2.0 CPU Units, individual program tasks could not be downloaded from the CX-Programmer. It was only possible to download the entire user program.

For example, if several programmers were developing the program, the project manager had to unify each program after debugging and then download the entire user program. Furthermore, the entire user program had to be downloaded even if just a few changes were made.

Note It was possible to upload individual program tasks with CS/CJ-series PLCs.

Task read protection prevents anyone from displaying, editing, or uploading the read-protected set of tasks from CX-Programmer without inputting the correct password. In this case, the entire program can be uploaded, but the readprotected tasks cannot be displayed or edited without inputting the correct password. Tasks that are not read-protected can be displayed, edited, or modified with online editing.

2. The entire program can be transferred to another CPU Unit even if individual tasks in the program are read-protected. It is also possible to connect online and create a program file (.OBJ file) with file memory operations. In both cases, the task read protection remains effective for the passwordprotected tasks.

3. When the CX-Programmer is used to compare a user program in the computer's memory with a user program in the CPU Unit, password-protected tasks will be compared too.

Function block definitions can be read even if the entire program or individual tasks in a program containing function blocks (CPU Unit Ver. 3.0 or later only) are read-protected.

Enabling/Disabling Creating File Memory Program Files

Previous CPU Units (PreVer. 2.0 CPU Units)

CPU Unit Ver. 2.0 or Later and CX-Programmer Ver. 4.0 or Higher

With the pre-Ver. 2.0 CS/CJ-series CPU Units, it was possible use file memory operations to transfer a program file (.OBJ file) to a Memory Card even if the program was protected with UM read protection. (Consequently, illegal copies could be made.)

Overview

When the entire program or individual tasks in a CPU Unit Ver. 2.0 or later are read-protected from the CX-Programmer, an option can be set to enable or disable the creation/backup of .OBJ program files. It will not be possible to create program files (.OBJ files) with file memory operations if the creation/ backup of program files is prohibited with this setting. (This setting prohibits both online transfers to a Memory Card/EM file memory as well as offline storage of PLC data that was uploaded to the CX-Programmer.)

Disabling the creation of file memory program files can help prevent illegal copying of the user program.

Description

1-6-3 Write Protection from FINS Commands Sent to CPU Units via

Networks

Previous CPU Units (Pre-Ver. 2.0 CPU Units)

With the pre-Ver. 2.0 CS/CJ-series CPU Units, there was no way to prohibit write operations and other editing operations sent to the PLC's CPU Unit as FINS commands through a network such as Ethernet, i.e., connections other than direct serial connections.

CPU Unit Ver. 2.0 or Later

Summary With the CPU Unit Ver. 2.0 and later CS/CJ-series CPU Units, it is possible to

prohibit write operations and other editing operations sent to the PLC's CPU Unit as FINS commands through a network (including write operations from CX-Programmer, CX-Protocol, CX-Process, and other applications using FinsGateway). Read processes are not prohibited.

FINS write protection can disable write processes such as downloading the user program, PLC Setup, or I/O memory, changing the operating mode, and performing online editing.

It is possible to exclude selected nodes from write protection so that data can be written from those nodes.

An event log in the CPU Unit automatically records all write processes sent through the network and that log can be read with a FINS command.

Example:

CJ1-H/CJ1M CPU Unit Ver. 2.0 Upgrades Section 1-6

Usage The system can be configured so that a PLC can be written only from autho-

rized nodes in the network. (For example, use this function when the system's control/monitoring computer is the only node allowed to write to a Controller within a piece of equipment.)

By limiting the number of nodes that can write to the PLC, it is possible to prevent system problems caused by unintentional overwrites during data monitoring.

Operations from CX-Programmer (including CX-Net) through the Network

The following CX-Programmer (including CX-Net) operations are restricted by FINS write protection when performed on the CPU Unit through the network.

Operations not allowed through the network when FINS write protection is enabled.

Note 1. FINS write protection does not prevent CX-Programmer operations from a

computer connected through a direct serial connection.

2. FINS write protection does not prevent the following file memory write operations.

• Automatic transfer from the Memory Card at startup

• Simple backup function (including backup operations to selected Units/Boards)

• Writing files with the FWRIT (WRITE DATA FILE) instruction

• Changing the Operating Mode

• Transferring the ladder program to the CPU Unit

• Transferring parameter area data (PLC Setup, I/O table, and CPU Bus Unit Setup) to the CPU Unit

• Transferring memory area data (I/O memory data) to the CPU Unit

• Transferring the variable table, comments, or program index to the CPU Unit

• Forced Set/Reset

• Changing timer/counter set values

• Online editing

• Writing file memory

• Clearing the error log

• Setting the clock

• Releasing the access right

• Transferring the routing table

• Transferring the data link table

Operations from Other Support Software

FINS write protection also prevents the following operations performed through the network by the CX-Protocol and CX-Process.

• Changing the CPU Unit's operating mode, writing memory areas, transferring PLC Setup settings, transferring the I/O table, forced set/ reset, and clearing the CPU Unit's error log

Operations from Applications That Use FinsGateway

FINS write protection prevents all write operations addressed to the CPU Unit from applications that use FinsGateway, such as PLC Reporter and Compolet.

1-6-4 Online Network Connections without I/O Tables

Summary With CJ-series CPU Units, the CPU Unit can recognize a CPU Bus Unit (such

as a Network Communications Unit, see note) even if the I/O tables have not been created and there is no registered I/O tables as a result of using automatic I/O allocation at startup.

CJ1-H/CJ1M CPU Unit Ver. 2.0 Upgrades Section 1-6

CPU Bus Unit (including Network Communications Units)

CS/CJ-series CPU Unit Ver.2.0 or higher

Network

Online connection can be made.

CPU Bus Units (including Network Communications Units) can be recognized before I/O tables are created (I/O allocation at startup is used).

Note Network Communications Units include Ethernet Units, Controller Link Units,

SYSMAC Link Units, and DeviceNet Units.

Usage If the nodes are connected to the network, this function allows a computer-

based Programming Device (such as the CX-Programmer) to connect online to PLCs in the network even if the I/O tables have not been created. Since a network connection is established with the PLCs, setup operations can be performed such as creating the I/O tables (or editing and transferring I/O tables), transferring the user program, transferring the PLC Setup, and transferring the CPU Bus Unit Setup.

This function is particularly useful when connecting the CX-Programmer via Ethernet (using a CS1W-ETN21), because the I/O tables can be created through Ethernet so a serial cable isn't required and it isn't necessary to spend extra time establishing a serial connection.

1-6-5 Communications through a Maximum of 8 Network Levels

Previous CPU Units (Pre-Ver. 2.0 CPU Units)

With the pre-Ver. 2.0 CPU Units, it was possible to communicate through 3 network levels max. (see note), including the local network. It was not possible to communicate through 4 or more levels.

Note A Gateway to the network via serial communications was not counted as a

level.

CPU Unit Ver. 2.0 or Later

Summary With the CPU Unit Ver. 2.0 and later CS/CJ-series CPU Units, it is possible to

communicate through 8 network levels max. (see note), including the local network.

Note 1. FINS commands can only be sent across up to 8 network levels when the

destination is a CPU Unit. FINS commands can be sent to other destinations up to 3 network levels away.

2. This functionality is enabled only after setting routing tables with the CXNet in CX-Programmer version 4.0 or higher.

3. A Gateway to the network via serial communications was not counted as a level.

Compatible Networks

Only the following 2 kinds of networks can be used when communicating through a maximum of 8 networks. The network levels can be combined in any order.

• Controller Link

• Ethernet

Note Communications are restricted to a maximum of 3 networks through

DeviceNet and SYSMAC Link networks.

Configuration of Compatible Models

All of the CPU Units must be CPU Unit Ver. 2.0 and later CS/CJ-series CPU Units. Also, the Gateway Counter Setting must be made with the CX-Net.

Operating Procedure There is no special procedure that must be performed for CS/CJ-series CPU

Units Ver. 2.0 or later. Just set normal routing tables to enable communicating across up to 8 network levels.

Note 1. When using communications only for up to 3 network levels, the CS/CJ-se-

ries CPU Units Ver. 2.0 or later can be used together with other CPU Units. When using communications for to 4 to 8 network levels, use only CS/CJseries CPU Units Ver. 2.0 or later. Other CPU Units cannot be used. Routing errors (error codes 0501 to 0504 hex) may occur in the relaying PLCs, preventing a FINS response from being returned.

2. With CS/CJ-series CPU Units with unit version 2.0 or later, the Gateway Counter (GCT: Number of allowed bridge passes) for FINS command/response frames is the value decremented from 07 hex (variable). (In earlier versions, the value was decremented from 02 hex.) With unit version 3.0 or later, the default GCT for FINS command/response frames is the value decremented from 02 hex. CX-Net can be used to select 07 hex as the value from which to decrement.

3. Do not use the Gateway Counter (GCT: Number of allowed bridge passes) enclosed in the FINS header of the FINS command/response frame in ver-

CJ1-H/CJ1M CPU Unit Ver. 2.0 Upgrades Section 1-6

ification checks performed by user applications in host computers. The GCT in the FINS header is used by the system, and a verification error may occur if it is used to perform verification checks in user applications, particularly when using CS/CJ-series CPU Units with unit version 2.0 or later.

1-6-6 Connecting Online to PLCs via NS-series PTs

Summary The CX-Programmer can be connected online to a PLC connected via a serial

line to an NS-series PT that is connected to the CX-Programmer via Ethernet (see note 2). This enables uploading, downloading, and monitoring the ladder program and other data.

1-6-8 Automatic Transfers at Power ON without a Parameter File

Previous CPU Units (Pre-Ver. 2.0 CPU Units)

Previously with the CS/CJ-series CPU Units, both the program file for automatic transfer at power ON (AUTOEXEC.OBJ) and the parameter file for automatic transfer at power ON (AUTOEXEC.STD) had to be stored on the Memory Card to enable automatic transfers to the CPU Unit at power ON. Also, the parameter file for automatic transfer at power ON (AUTOEXEC.STD) could not be created without the actual PLC (regardless of whether it was made in online operations from the CX-Programmer or a Programming Console or by using the easy backup operation).

Even if a program file (.OBJ) was created offline without the actual PLC and then sent to a remote PLC as an email attachment, the program file could not be transferred to the CPU Unit without a Programming Device.

CPU Unit Ver. 2.0 or Later

Summary With CS/CJ-series CPU Unit Ver. 2.0, the user program can be automatically

transferred to the CPU Unit at power ON without a parameter file (.STD) if the name of the program file (.OBJ) is changed to REPLACE.OBJ on the CX-Programmer and the file is stored on a Memory Card. If data files are included with the program file using this function, the following data file names are used: REPLACE.IOM, REPLCDM.IOM, REPLCE@.IOM.

Note 1. If the Memory Card contains a REPLACE.OBJ file, any parameter file on

the Memory Card will not be transferred.

2. If the Memory Card contains both a REPLACE.OBJ file and a AUTOEXEC.OBJ file, neither will be transferred.

Personal computer

Note With CX-Programmer Ver. 3.0 or higher, a program file (.OBJ) can be created

offline and saved on a computer storage media. Select Transfer - To File from the PLC Menu. This enable creating a program file offline without a PLC so that the name can be changed to enable sending the program file.

1-6-9 Operation Start/End Times

Previous CPU Units (Pre-Ver. 2.0 CPU Units)

The time that operation started and the time operation ended were not stored in the CPU Unit.

CPU Unit Ver. 2.0 or Later

The times that operation started and ended are automatically stored in the Auxiliary Area.

CJ1-H/CJ1M CPU Unit Ver. 2.0 Upgrades Section 1-6

• The time that operation started as a result of changing the operating mode to RUN or MONITOR mode is stored in A515 to A517 of the Auxiliary Area. The year, month, day, hour, minutes, and seconds are stored.

• The time that operation stopped as a result of changing the operating mode to PROGRAM mode or due to a fatal error is stored in A518 to A520 of the Auxiliary Area. The year, month, day, hour, minutes, and seconds are stored.

This information simplifies managing PLC System operating times.

1-6-10 Automatic Detection of I/O Allocation Method for Automatic

Transfer at Power ON

Previous CPU Units (Pre-Ver. 2.0 CPU Units)

Previously with the CJ-series CPU Units, when a parameter file for automatic transfer at power ON (AUTOEXEC.STD) was recorded in a Memory Card, the user-set I/O allocation method was automatically used when an automatic transfer at power ON was executed from the Memory Card, and I/O was allocated according to the parameter file for automatic transfer at power ON. As a result, the following case occurred:

1,2,3... 1. In an office where Units were not mounted, the CX-Programmer was con-

nected online to just the CPU Unit, and files for automatic transfer at power ON were created (without creating/transferring I/O tables).

2. These files for automatic transfer at power ON were then saved in the Memory Card, which was then taken to the remote site where automatic transfer at power ON was executed.

3. When automatic transfer at power ON was executed, I/O tables were created based on the parameter file for automatic transfer at power ON saved in the Memory Card (i.e., the file created when Units were not mounted to the PLC). As a result, the registered I/O tables did not match the Units actually mounted in the CPU Unit, causing an I/O setting error.
