xxiv

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

Safety Precautions 3

• The PLC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe f ailure alarm (FALS) instruction is execut ed. Unexpected operation, however, may still occur for errors in the I/O control section, errors in I/O memory, and errors that cannot be detected by the self-diagnosis function. As a countermeasure for all these errors, external safety measures must be provided to ensure safety in the system.

• The PLC or outputs may remain ON or OFF due to deposits on 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.

!WARNING 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 ot her causes. Not doing so may result in serious accidents.

!WARNING Do not apply the voltage/current outside the specified range to this unit. It may

cause a malfunction or fire.

!Caution

Execute online edit only after confirming that no adverse effects will be cau sed 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 editing the I/O 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 to the torque specified in this manual. The loose screws may result in burning or malfunctio n.

!Caution Do not touch anywhere near the power supply parts or I/O terminals while the

power is ON, and immediately after turning OFF the power. The hot surface may cause burn injury.

• Check that the DIP switches and data memory (DM) are properly set before starting 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.

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

• Confirm that no adverse effect will oc cur 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.

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

• Do not place objects on top of the cables. Doing so may break the cables.

• 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 the Unit, be sure to firs t touch a grounded metallic object in order to discharge any static buildup. Not doing so may result in malfunction or damage.

• Install the Unit properly as specified in the operation manual. Improper installation of the Unit may result in malfunction.

• Do not touch the Expansion I/O Unit Connecting Cable while the power is being supplied in order to prevent malfunction due to static electricity.

• Do not turn OFF the power supply to the Unit while data is being transferred.

• When transporting or storing the product, cover the PCBs and the Units or put there in the antistatic bag with electrically conductive materials to prevent LSls and ICs from being damaged by static electricity, and also keep the product within the specified storage temperature range.

• Do not touch the mounted parts or the rear surface of PCBs because PCBs have sharp edges such as electrical leads.

• Double-check the pin numbers when assembling and wiring the connectors.

• Wire cor re ct l y accord in g to spec ifie d pr oc ed ur es.

xxviii

Application Precautions 5

• Do not connect pin 6 (+5V) on the RS-232C Option Board (CP1W-CIF01) on the CPU Unit to any external device other than the NT-AL001 or CJ1W-CIF11 Conversion Adapter. The external device and the CPU Unit may be damaged.

• Use the dedicated connecting cables specified in this manual to connect the Units. Using commercially available RS-232C computer cables may cause failures in external devices or the CPU Unit.

• The user progr am an d pa ramet er ar ea d ata in the CPU Unit is b acked up in the built-in 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.

• Do not turn OFF the power supply to the PLC while the Memory Cassette is being written. Doing so may corrupt the data in the Memory Cassette. The BKUP indicator will light while the Memory Cassette is being written. Wait for the BKUP indicator to go out before turning OFF the power supply to the PLC.

• Before replacing the battery, supply power to the CPU Unit for at least 5 minutes and then complete battery rep lacement within 5 minutes of turn OFF the power supply. Memory data may be corrupted if this precaution is not observed.

• Always use the following size wire when connecting I/O terminals:

AWG22 to AWG18 (0.32 to 0.82 mm

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

• UL standards required that batteries be replaced only by experienced technicians. Do not allow unqualified persons to replace batteries. Also, always follow the replacement procedure provided in the manual.

• Never short-circuit the positive and negative terminals of a battery or charge, disassemble, heat, or incinerate the battery. Do not subject the battery to strong shocks or deform the barry by applying pressure. 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.

• Always construct external circuits so that the power to the PLC it turned ON before the power to the control system is turned ON. 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.

xxix

Conformance to EC Directives 6

• 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 stop s for a fatal erro r, including tho se produced with the FALS(007) instruction, all outputs from Output Unit will be turned OFF and only the internal output status will be maintained.)

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 The applicable EMC (Electromagnetic Compatibility) standard is EN61131-2.

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 CP1L-EL/EM PLCs comply with EC Directives. To ensure that the machine or device in which the CP1L-EL/EM PLC is used complies with EC Directives, the PLC must be installed as follows:

1,2,3... 1. The CP1L-EL/EM PLC must be installed within a control panel.

2. You must use reinforced insulat ion or double insu lation for the DC po wer supplies used for I/O Units and CPU Units requiring DC power. The output holding time must be 10 ms minimum for the DC power supply connected to the power supply terminals on Units requiring DC power.

3. CP1L-EL/EM PLCs complying with EC Directives also conform to EN61131-2. Radiated emission characteristics (10-m regulations) may vary depending on the configuration of the control p anel 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

The CP1L-EL/EM PLCs conforms to the Common Emission Standards (EN61131-2) 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.

Countermeasures

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 frequ ency of loa d switching for the whol e system with the PLC included is more than 5 times per minute.

Note Refer to EN61131-2 for more details.

Countermeasure Examples

When switching an inductive load, connect an surge protector, diodes, etc., in parallel with the load or contact as shown below.

Circuit Current Characteristic Required element

AC DC

Yes Yes If the load is a relay or solenoid, there is

a time lag between the moment the circuit is opened and the moment the load is reset.

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

No Yes The diode connected in parallel with

the load changes energy accumulated by the coil into a current, which then flows into the coil so that the current will be converted into Joule heat by the 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.

The capacitance of the capacitor must be 1 to 0.5

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.

Varistor method

load

Circuit Current Characteristic Required element

AC DC

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 circuit 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.

When switching a load with a high inrush current such as an incandescent lamp, suppress the inrush current as shown below.

Full Complement of High-speed Counter Functions

High-speed counter inputs can be us ed by connectin g rotary encoder s to the built-in inputs. The ample number of high-speed counter inputs makes it possible to control a multi-axis device with a single PLC.

• Four 100 kHz (single phase)/50 kHz (differential phases) high-speed counter inputs (4 counters/2 axes) are provided as a standard feature. (See note.)

Full Complement of Highspeed Counter Functions

Note Settings in the PLC Setup determine whether each input point is to

be used as a normal input, interrupt inp ut, quick-re sponse input, or high-speed counter.

High-speed Processing for High-speed Counter Present Value (PV) Target Values or Range Comparison Interrupts

An interrupt task can be started when the count reaches a specified value or falls within a specified range.

High-speed Counter Input Frequency (Speed) Monitoring

The input pulse frequency can be monitored using the PRV instruction (one point (counter 0) only, and you must select whether to use input frequency monitoring or counter 3; you cannot use both).

High-speed Counter PV Holding/Refreshing

It is possible to toggle between holding and refreshing the high-speed counter PV by turning ON and OFF the High-speed Counter Gate Flag from the ladder program.

Versatile Pulse Control (CPU Units with Transistor Outputs Only)

Positioning and speed control by a pulse-input servo driver is enabled by outputting fixed duty ratio pulse output signals from the CPU Unit's built-in outputs.

• Pulse outputs for 2 axes at 100 kHz maximum are provided as standard features. (See note.)

Full Complement of Pulse Output Functions

Note The instruction used to control each output point determines

whether it is used as a normal output, pulse output, or PWM output.

Select CW/CCW Pulse Outputs or Pulse Plus Direction Outputs for the Pulse Outputs

The pulse outputs can be selected to match the pulse input specifications of the motor driver.

Easy Positioning with Absolute Coordinate System Using Automatic Direction Setting

For operations in an absolute coordinate system (i.e., when the origin is established or when the PV is ch anged by the INI instru ction), the CW/CCW direction can be automatically set when PULSE OUTPUT instructions are executed according to whether the specified number of output pulses is more or less than the pulse output PV.

Triangular Control

If the amount of output pulses r equired for ac celeration an d deceleration (the target frequency times the time to reach the target frequency) exceeds the preset target number of output pulses during positioning (when the ACC instruction in independent mode or the PLS2 instruction is executed), the acceleration and deceleration will be shortened and triangular control will be executed instead of trapezoidal control. In other words, the trapezoidal pulse output will be eliminated, with no period of constant speed.

Target Position Changes during Positioning (Multiple Start)

While positioning using a PULSE OUTPUT (PLS2) instruction is in progress, the target position, target speed, acceleration rate, and deceleration rate can be changed by executing another PLS2 instruction.

Features and Main Functions Section 1-1

Positioning Changes during Speed Control (Interrupt Feeding)

While speed control in continuous mode is in effect, it is possible to change to positioning in independent mode by executing a PULSE OUTPUT (PLS2) instruction. By this means, interrupt feeding (moving a specified amount) can be executed under specified conditions.

Target Speed, Acceleration Rate, and Deceleration Rate Changes during Acceleration or Deceleration

When a PULSE OUTPUT instruction with trap ezoidal acc eleration an d deceleration is executed (for speed control or positioning), the target speed and acceleration and deceleration rates can be changed during acceleration or deceleration.

Lighting and Power Control by Outputting Variable Duty Ratio Pulses

Operations, such as lighting and power control, can be handled by outputting variable duty ratio pulse (PWM) output signals from the CPU Unit's built-in outputs.

Origin Searches Origin Search and Origin Return Operations Using a Single Instruction

An accurate origin search combining all I/O signals (origin proximity input signal, origin input signal, positioning completed signal, error counter reset output, etc.) can be executed with a single instruction. It is also possible to move directly to an established origin using an origin return operation.

Input Interrupts In direct mode, an interrupt task can be started when a built-in input turns ON

or OFF. In counter mode, the rising or falling edges of built-in inputs can be counted, and an interrupt task started when the count reaches a specified value. The maximum number of interrupt input points is 6 for CPU Units with 20, 30 or 40 I/O points.

Note For each input point, a selection in the PLC Setup dete rmines whethe r it is to

be used as a normal input, interrupt input, quick-response input, or highspeed counter. The interrupt input response frequency in counter mode must be 5 kHz or less total for all interrupts.

Quick-response Inputs

Note For each input, a PLC Setup parameter determines whether it is to be used as

By using quick-response inputs, built-in inputs up to a minimum input signal width of 50 μs can be read regardless of the cycle time. The maximum number of quick-response input points is 6 for CPU Units with 20, 30 or 40 I/O points.

a normal input, interrupt input, quick-response input, or high-speed counter.

Built-in Analog Input The CPU Units have analog functionality, with 2 analog voltage inputs built in.

External analog values of 0 to 10 V (resolution: 1000) are converted to digital values and stored in a word in the AR Area. This enables applications that require on-site adjustment of settings that do not demand a high degree of accuracy, such as for example, a setting based on changes in outdoor temperatures or potentiometer inputs.

Communications can be executed independently of the program by setting a Modbus-RTU command in the DM and turning ON a software switch.

Expansion Capability for Serial Ports

Up to two Serial Communications Boards each with one RS-232C port or one RS-422A/485 port can be added to a CPU Unit with 30 or 40 I/O points. One Serial Communications Boards can be added to a CPU Unit with 20 I/O points. With the serial communications port, it is easy to simultaneously connect a computer, PT, PLC, and/or various components, such as an Inverter, Temperature Controller, or Smart Senso r.

Note (1) The Modbus-RTU easy master (available for all models) makes it easy to

control Modbus Slaves (such as Inverters) with serial communications. After the Modbus Slave address, function, and data have been preset in a fixed memory area (DM), messages can be sent or received independently of the program by turning software switches.

If an attempt is made to read a ladder program from a CX-Programmer, access to the program is denied if the password that is entered does not match the registered password. If incorrect passwords are entered for five consecutive attempts, the CPU Unit does not accept any more passwords for two hours.

With unit version 1.1 or later and CX-Programmer version 9.6 or higher, you can extend protection with UM read protection and task read protection to ensure better protection for your design assets.

1-2-3 Restrictions on System Configuration

The following restrictions apply to the CP-series Expansion Units and CPseries Expansion I/O Units that can be connected to CP1L-EL/EM CPU Units.

■ Number of Expansion Units and Expansion I/O Units Connected

A maximum of three Units can be connected to a CPU Unit with 30 or 40 I/O points and one Unit can be connected to a CPU Unit with 20 I/O points.

Each CPU Unit can connect one device to pin 6 (+5V power supply) of the CP1W-CIF01 RS232C Option Board.

If two CP1W-CIF01 Option Boards are mounted on a CPU Unit with 30, 40 or 60 IO points and both of which use pin 6 (+5V power supply), a total of up to two Expansion Units can be connected to the CPU Unit.

■ Restrictions on the number of simultaneously ON output points

CP1W-32ER/32ET/32ET1’s maximum number of simultaneously ON points is 24 (75%).

■ Restrictions Imposed by Ambient Temperature

There are restrictions in the power supply voltage and output load current imposed by the ambient temperature for CPU Units with DC power. Use the CPU Unit within the following ranges of power supply voltage and output load current.

1-4 Function Blocks

Function blocks can be used in programming SYSMAC CP-series PLCs.

1-4-1 Overview of Function Blocks

A function block is a basic program element containing a standard processing function that has been defined in advance. Once the function block has been defined, the user just has to insert the function block in the program and set the I/O in order to use the function.

As a standard processing function, a function block is not created with actual physical addresses, but local variables. The user sets parameters (addresses or values) in those variables to use the function block. The addresses used for the variables themselves are automatically assigned by the system (CX-Programmer) each time they are placed in the program.

In particular, each function block is saved by the CX-Programmer as an individual file that can be reused with programs for other PLCs. This makes it possible to create a library of standard processing functions.

Function Blocks Section 1-4

1-4-2 Advantages of Function Blocks

Function blocks allow complex programming units to be reused easily. Once standard program sections have been created as function blocks and saved in files, they can be reused just by placing a function block in a program and setting the parameters for the function block's I/O. Reusing standa rdized function blocks reduces the time required for programming/debugging, reduces coding errors, and makes programs easier to un de rs ta nd .

Improved Reusability through Programming with Variables

Structured programs created with function blocks have better design quality and required less development time.

The I/O operands are displayed as local variable names in the program, so the program is like a “black box” when entering or r eading the pr ogram and n o extra time is wasted trying to understand the internal algorithm.

Many different processes can be created easily from a single function block by using input variables for the parameters (such as timer SVs, control constants, speed settings, and travel distances) in the standard process.

debugged can be reused.

outside, so the data can be protected. (Data cannot be changed unintentionally.)

The function block's I/O is entered as local variables, so the data ad dresses i n the function block do not have to be changed as they do when copying and reusing a program section.

Creating Libraries Processes that are independent and reusable (such as processes for individ-

ual steps, machinery, equipment, or control systems) can be saved as function block definitions and converted to library functions.

The function blocks are created with local variable names that are not tied to physical addresses, so new programs can be developed easily just by readin g the definitions from the file and placing them in a new program.

Nesting Multiple Languages

Mathematical expressions can be entered in structured text (ST) language. Nesting function blocks is supported for CX-Programmer Ver. 6.0 or higher.

For example, it is possible to express only special operations in ST language within a function block in a ladder diagram.

Note (1) The above values and for a cold start for a DC power supply.

• A capacitor delay circuit is used in the inrush current control circuitry for the DC power supply. The capacitor will not be charged if a hot start is performed when the power supply has been OFF for only a short time, so in those cases the inrush current values may be higher (as much as two times higher) than those shown above.

Always allow for this when selecting fuses and brea kers for e xter nal cir cuits.

Specifications Section 2-2

(2) This is the rated value for the maximum system configuration. Use the fol-

lowing formula to calculate DC power consumption for CPU Units with DC power.

Formula: DC-powered CP1L-EL/EM power consumption = (5 V current consumption × 5 V/70% (CP1L-EL/EM internal power efficiency) + 24 V current consumption × 24 V) × 1.1 (current fluctuation factor)

2-3 CP1L-EL/EM CPU Unit Operation

2-3-1 Overview of CPU Unit Configuration

The CP1L-EL/EM CPU Unit memory consists of the following blocks.

(1) • Data is backed up from RAM to the built-in flash memory when

(2) • A CX-Programmer operation can be used to transfer DM Area initial

(3) • CX-Programmer operations can be used to transfer data from RAM to

changes are made, e.g., from the CX-Programmer.

• When the power supply is turned ON, data is transferred from the builtin flash memory to RAM.

values from RAM to the built-in flash memory.

• The PLC Setup can be set so that DM Area initial values are transferred from the built-in flash memory to RAM when the power supply is turned ON.

the Memory Cassette or from the built-in flash memo ry to th e Memory Cassette.

CP1L-EL/EM CPU Unit Operation Section 2-3

• When the power supply is turned ON, data is transferred from the Memory Cassette to the built-in flash memory and RAM. Data can also be transferred from the Memory Cassette to the built-in flash memory and RAM using the CX-Programmer.

User Program The user program consists of up to 288 tasks, including interrupt tasks. Each

task is programmed from the CX-Programmer and then transferred to the CPU Unit.

There are two types of tasks: cyclic tasks and interrupt tasks. Cyclic tasks are executed once each cycle and interrupt tasks are executed only when the interrupt conditions are met. There can be up to 32 cyclic tasks and up to 256 interrupt tasks. Cyclic tasks are executed in the order of the task numbers.

Instructions programmed in the tasks are executed in order from the first instruction and then I/O memory is refreshed. When all cyclic tasks have been executed, I/O refreshing with PLC Units is performed and then the cyclic tasks are executed again starting from the one with the lowest task number. This is called the cyclic scan method.

I/O Memory The I/O memory area is a RAM area read and written by the user. Some parts

of the I/O memory are cleared when the power is interrupted. Other parts are maintained. There are parts that used for data exchange with PLC Units and parts that are used internally.

There are two ways to refresh the parts of I/O memory used for data exchange with PLC Units: Once each program execution cycle and immediately when needed when executing specific instructions.

Parameter Area In addition to the I/O memory used as instructions operands by the user, there

is also a separate memory area that can be manipulated only from the CXProgrammer. This area, called the parameter area, contains the following.

• PLC Setup

• Routing tables

PLC Setup The PLC Setup contains configuration parameters that can be set by the user

to define the basic specifications of the CPU Unit. Included are serial port settings, a minimum cycle time setting, and other parameters. For details, refer to the CX-Programmer Operation Manu al.

Routing Tables Tables specifying the communications paths from the Communications Units

on the local PLC to remote PLCs connected on other networks must be registered in all the CPU Units in network PLCs to send and receive data between networks. These tables are called the routing tables. The routing tables consist of the relay network table and local network table.

Routing tables are created from the CX-Programmer or Support Software for Communications Units (e.g., CX-Integrator) and then transferred to each CPU Unit.

The remote network tables lists the node number and network address of the first relay node that must be passed through to reach any remote network to which the PLC is not directly connected. Once the routing tables have been registered, any remote network can be reached by passing through relay nodes.

Local Network Table

The local network table contains the unit number and network address of all Communications Units that are part of the local PLC.

Built-in Flash Memory Flash memory is built into the CP1L-EL/EM CPU Units. Data in the following

areas is automatically backed up to the flash memory whenever it is written in any way other than by instructions in the user program, e.g., when the CXProgrammer or PT is used to transfer or edit data , edit the pr ogram online, or transfer data from a Memory Cassette.

• User program area

• Parameter area (PLC Setup and routing tables)

The next time the power supply is turned ON, the data in the built-in flash memory is automatically transferred to user memory (i.e., the user program area and parameter area).

It is also possible to save data from data areas in I/O me mory in the built-in flash memory using operations from the CX-Programmer.

The symbol table, comment file, and program index file can be stored in the comment memory in flash memory. When the program is transferred from the CX-Programmer to the CPU Unit, function block program information is also stored automatically in flash memory.

flash memory is being written or the Memory Cassette is being accessed. Never turn OFF the power supply to the CPU Unit when the BKUP indicator is lit.

Memory Cassette Memory Cassettes can be used as required in system operation and mainte-

Note The BKUP indicator on the front of the CPU Unit will light whenever the built-in

nance. For example, they can be used to save programs, data memory contents, PLC Setup data, or I/O comments from the CX-Programmer. The contents of a Memory Cassette can also be automatically transferred if desired.

CPU Unit Operation Section 2-4

2-4-2 I/O Refreshing and Peripheral Servicing

I/O Refreshing I/O refreshing involves cyclically transferring data with external devices using

preset words in memory. I/O refreshing includes the following:

• Refr eshing betw een I/O w ords in th e CIO Area and CPU Unit built-in I/O, CP-series Expansion Units, and CP-series Expansion I/O Units.

All I/O refreshing is performed in the same cycle (i.e., time slicing is not used). I/O refreshing is always performed after program execution.

Units Max. data exchange Data exchange area

CPU Unit built-in I/O 2 input words

2 output words

CP-series Expansion Units and Expansion I/O Units

Fixed depending on Units I/O Bit Area

Peripheral Servicing Peripheral servicing involves servicing non-scheduled events for external

devices. This includes both events from external devices and service re quests to external devices.

Most peripheral servicing involves FINS commands. The specific amount of time set in the system is allocated to each type of servicing and executed every cycle. If all servicing cannot be completed within the allocated time, the remaining servicing is performed the next cycle.

Service Description

Ethernet port servicing • Non-scheduled servicing for communicati ons

(either sending or receiving) via the Ethernet port.

Serial port servicing •Non-scheduled servicing for FINS or Host Link

commands received via a serial port from the CXProgrammer, PTs, or host computers (e.g., requests for program transfers, monitoring, forcedset/reset operations, or online editing)

• Non-scheduled servicing from the CPU Unit transmitted from a serial port (non-solicited communications)

Communications port servicing

Built-in flash memory access servicing

Memory Cassette access servicing

•Servicing to execute network communicati o ns or serial communications for the SEND, RECV, CMND instructions using communications ports 0 to 7 (internal logical ports)

• Servicing to execute background execution using communications ports 0 to 7 (internal logical ports)

• Read/write processing for built-in flash memory

•Read/write processing for a Memory Cassette

I/O Bit Area

Note (1) Ethernet port, serial port, and communications port servicing is allocated

8% of the previous cycle time by default (the default can be changed) for each service. If servicing is separated over many cycles, delaying completion of the servicing, set the same allocated time (same time for all services) rather than a percentage under execute time settings in the PLC Setup.

(2) An error will be occurred if the cycle time is too long. Modify the CX-Pro-

grammer’s response monitoring time longer according to the following method. Start the CX-Programmer. Select Change Model from the PLC Menu. The Change PL C Dialog Box will be displayed. Click the Settings Button

on the right side of Network Type. The Network Settings [USB] Dialog Box will be displayed. Click the Network Tab and increase the value in Response Timeout(s).

CPU Unit Operation Section 2-4

2-4-3 I/O Refresh Methods

I/O for CPU Unit built-in I/O and I/O on CP-series Expansion Units and Expansion I/O Units is performed at the following times.

1,2,3... 1. Cyclic refresh period

2. When instructions with an immediate refresh variation are executed

3. When IORF(097) is executed

Cyclic Refreshing I/O is refreshed after all the instructions in executable tasks have been exe-

cuted.

Note (1) Immediate refreshing is possible only for the Built-in I/O Area. Use

IORF(097) for I/O on CP-series Expansion Units and Expansion I/O Units.

(2) Refreshing Range

• Bit Operands The ON/OFF status of the 16 I/O points allocated to the word containing the specified bit will be refreshed.

• Word Operands The ON/OFF status of the 16 I/O points allocated to the specified word will be refreshed.

(3) Refresh Timing

• Input or source operands are read just before the instruction is executed.

• Output or destination (results) operands are written just after the instruction is executed.

CPU Unit Operation Section 2-4

(4) Using instructions with the immediate refresh option, instruction execu-

tion time will be increased, increasing the overall cycle time. Be sure to confirm that this will not adversely affect system operation.

IORF(097) Refreshing When IORF(097) (I/O REFRESH) is executed, the I/O bits in the specified

range of words are refreshed. IORF(097) can be used for CP-series Expansion Units and CP-series Expansion I/O Units.

Example

If high-speed response is required from input to output, execute IORF(097) before and after the relevant instructions.

Note IORF(097) has a relatively long execution time which increases with the num-

ber of words being refreshed. Be sure to consider the affect of this time on the overall cycle time. Refer to the CP Series Programmable Cont rollers Progr am- ming Manual for instruction execution times.

2-4-4 Initialization at Startup

The following initializing processes will be performed once each time the power is turned ON.

• Conf irm mo un te d Un its an d I/O alloc at ion s.

• Clear the non-holding areas of I/O memory according to the status of the IOM Hold Bit. (See note 1.)

• Clear forced status according to the status of the Force d Status Hold B it. (See note 2.)

2-6-1 Overview

The following processing is performed when CPU Unit power is turned OFF. Power OFF processing will be performed if the power supply voltage falls below the specified value while the CPU Unit is in RUN or MONITOR mode.

1,2,3... 1. The CPU Unit will stop.

2. Outputs from all Output Units will be turned OFF.

Note (1) All outputs will turn OFF despite the status of the I/O Memory Hold Bit or

I/O Memory Hold Bit at power ON settings in the PLC Setup.

(2) DC Power

85% of rated voltage: 20.4 V DC or less

The following processing will be performed if power drops only momentarily (momentary power interruption).

1,2,3... 1. The system will continue to run unconditionally if the momentary power in-

terruption lasts less than 2 ms for DC power, i.e., the time it takes the rated voltage at 85% or less to return to 85% or higher is less than 2 ms for DC power.

2. A momentary power interruption that lasts more than 2 ms for DC power may or may not be detected.

Power OFF Operation Section 2-6

Power OFF detection time: The time from when the power supply voltages drops to 85% for DC power until the power OFF condition is detected.

Holding time for 5 V internal power supply after power OFF detection: The maximum time that the 5 V internal power supply voltage will be maintained after the power OFF condition is detected. The holding time is fixed at 1 ms.

DC: 85% of rated voltage

Operation always stopped at this point regardless.

2-6-2 Instruction Execution for Power Interruptions

Power OFF will be detected if the DC power supply falls below 85% of the rated voltage for the power OFF detection time (2 ms minimum for DC power). The CPU reset signal will turn ON while the internal power supply is being held and the CPU Unit will be reset.

If power is interrupted and the interruption is detected when the CPU Unit is operating in RUN or MONITOR mode, the instruction currently being executed will be completed and then the CPU Unit will be reset.

Computing the Cycle Time Section 2-7

2-7-2 Cycle Time Overview

The cycle time depends on the following conditions.

• Type and number of instructions in the user program (in all cyclic tasks that are executed during a cycle, and within interrupt tasks for which the execution conditions have been satisfied)

• Type and number of CP-series Expansion Units and Expansion I/O Units

• Use of protocol macros and the largest communications message

• Fixed cycle time setting in the PLC Setup

• Use of Ethernet and serial ports

• Fixed peripheral servicing time in the PLC Setup

Note 1. The cycle time is not affected by the number of tasks that are used in the

user program. The tasks that affect the cycle time are those cyclic tasks that are READY in the cycle.

2. When the mode is switched from MONITOR mode to RUN mode, the cycle time will be extended by 10 ms (this will not, however, take the cycle time over its limit).

The cycle time is the total time required for the PLC to perform the five operations given in the following tables.

Cycle time = (1) + (2) + (3) + (4) + (5)

1: Overseeing

Details Processing time and fluctuation cause

Checks the I/O bus and user program memory, checks for battery errors, etc.

2: Program Execution

Details Processing time and fluctuation cause

Executes the user program, and calculates the total time time taken for the instructions to execute the program.

3: Cycle Time Calculation

Details Processing time and fluctuation cause

Waits for the specified cycle time to elapse when a minimum (fixed) cycle time has been set in the PLC Setup.

Calculates the cycle time.

4: I/O Refreshing

Total instruction execution time

When the cycle time is not fixed, the time for step 3 is approximately 0. When the cycle time is fixed, the time for step 3 is the preset fixed cycle time minus the actual cycle time ((1) + (2) + (4) + (5)).

I/O refresh time for each Unit multiplied by the number of Units used.

If there is no access, the servicing time is 0 ms.

2-7-3 Functions Related to the Cycle Time

Minimum Cycle Time Set the minimum cycle time to a non-zero value to elimina te inconsistencies in

I/O responses. A minimum cycle time can be set in the PLC Setup between 1 and 32,000 ms in 1-ms increments.

Minimum cycle time (effective)

Actual cycle time

This setting is effective only when the actual cycle time is shorter than the minimum cycle time setting. If the actual cycle time is longer than the minimum cycle time setting, the actual cycle time will remain unchanged.

The average cycle time for the past eight cycles can be read from the CX- Programmer.

Note The following methods are effective in reducing the cycle time.

• Place tasks that do not need to be executed on standby.

• Use JMP-JME instructions to skip instructions that do not need to be executed.

2-7-6 Online Editing Cycle Time Extension

When online editing is executed to change the program from the CX-Programmer while the CPU Unit is operating in MONITOR mode, the CPU Unit will momentarily suspend operation while the program is being changed. The period of time that the cycle time is extended is determined by the following conditions.

• Number of steps changed

• Editing operations (insert/delete/overwrite)

• Types of instr uc tio ns

The cycle time extension for online editing is negligibly affected by the size of task programs. If the maximum program size for a task is 10 Ksteps, the online editing cycle time extension will be as follows:

CPU Unit Increase in cycle time for online editing

CP1L-EL/EM CPU Unit Maximum: 16 ms, Normal: 12 ms

(for a program size of 10 Ksteps)

When editing online, the cycle time will be extended by according to the editing that is performed. Be sure that the additional time will not adversely affect system operation.

Note When there is one task, online editing is processed all in the cycle time follow-

ing the cycle in which online editing is executed ( written). When there are multiple tasks (cyclic tasks and interrupt tasks), online editing is separated, so that for n tasks, processing is executed over n to n × 2 cycles max.

2-7-7 I/O Response Time

The I/O response time is the time it takes from when an input turns ON, the data is recognized by the CPU Unit, and the user program is executed, up to the time for the result to be output to an output terminal. The length of the I/O response time depends on the following conditions.

• Timing of Input Bit turning ON.

• Cycle time.

Minimum I/O Response Time

The I/O response time is shortest when data is retrieved immediately before I/ O refresh of the CPU Unit. The minimum I/O response time is calculated as follows:

Minimum I/O response time = Input ON delay + Cycle time + Output ON delay

Note The input and output ON delays depend on the type of terminals used on the

CPU Unit or the model number of the Unit being used.

Maximum I/O Response Time

The I/O response time is longest when data is retrieved immediately after I/O refresh period of the CPU Unit. The maximum I/O response time is calculated as follows:

Maximum I/O response time = Input ON delay + (Cycle tim e × 2) + Output ON delay
