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

so may result in electric shock.

!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 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.

xxiv

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

Page 24

Safety Precautions 3

• 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 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 other causes. Not doing so may result in serious accidents.

!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 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 malfunction.

!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.

!Caution Pay careful attention to the polarities (+/-) when wiring the DC power supply. A

wrong connection may cause malfunction of the system.

!Caution When connecting the PLC to a computer or other peripheral device, either

ground the 0 V side of the external power supply or do not ground the external power supply at all. Otherwise the external power supply may be shorted depending on the connection methods of the peripheral device. DO NOT ground the 24 V side of the external power supply, as shown in the following diagram.

Operating Environment Precautions 4

!Caution After programming (or reprogramming) using the IOWR instruction, confirm

that correct operation is possible with the new ladder program and data before starting actual operation. Any irregularities may cause the product to stop operating, resulting in unexpected operation in machinery or equipment.

!Caution The CP1L CPU Units 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 Area, counter present values and Completion Flags, and HR Area), however, is not written to flash memory. The DM Area, counter present values and Completion Flags, and HR Area 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 Area, counter present values and Completion Flags, and HR Area are used to control external outputs, prevent inappropriate outputs from being made whenever the Battery Error Flag (A402.04) is ON.

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.

!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.

!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. Make sure that the operating environment is within the specified conditions at installation and remains within the specified conditions during the life of the system.

!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.

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

• Mount the Unit only after checking the connectors and terminal blocks completely.

• 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.

• Wire all connections correctly according to instructions in this manual.

• Always use the power supply voltage 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.

• Leave the label attached to the Unit when wiring. Removing the label may result in malfunction.

• 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.

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

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

Ω or less when installing the Units. Not connecting

Ω or less may result in electric shock.

Page 27

Application Precautions 5

• Be sure that the terminal blocks, connectors, Option Boards, and other items with locking devices are properly locked into place. Improper locking may result in malfunction.

• Disconnect the functional ground terminal when performing withstand voltage tests. Not disconnecting the functional ground terminal may result in burning.

• Wire correctly and double-check all the wiring or the setting switches before turning ON the power supply. Incorrect wiring may result in burning.

• 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 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.

• 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 first touch a grounded metallic object in order to discharge any static buildup. Not doing so may result in malfunction or damage.

• 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 with electrically conductive materials to prevent LSIs 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 correctly according to specified procedures.

• 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 CP1W-CIF11 Conversion Adapter. The external device and the CPU Unit may be damaged.

xxviii

Page 28

Application Precautions 5

• 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 program and parameter area data in the CPU Unit is backed 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 replacement 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.

• 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.)

Conformance to EC Directives 6

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

1,2,3... 1. The CP1L PLC must be installed within a control panel.

2. You must use reinforced insulation or double insulation for the DC power 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 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 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

The CP1L 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.

xxx

Page 30

Conformance to EC Directives 6

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 frequency of load switching for the whole 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

CR method

Powe r supply

Diode method

Powe r supply

Varistor method

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

Inductive

load

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

Inductive

load

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-

Inductive

load

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.

Positioning can be controlled using an inverter. Previous a internal pulse output with trapezoidal acceleration/deceleration is created using the PULSE OUTPUT instruction. The position offset is calculated using an error counter for the feedback pulse input from a rotary encoder connected to an inductive motor and the internal pulse output. The error counter is then used to output a speed command to the inverter to control positioning. This enables positioning with high-capacity motors, as well as low-cost positioning with small-capacity motors (in comparison to using a servo).

Page 39

Features and Main Functions Section 1-1

A virtual pulse output is created using a pulse output instruction, the position offset is calculated using an error counter, and a frequency (i.e., speed) command is output according to the position offset to control positioning.

vector control.

High-speed counter inputs can be enabled by connecting rotary encoders 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.)

24 built-in inputs (Functions can be assigned.)

High-speed counters (4 counters/2 axes) 100 kHz (single phase)

Full Complement of Highspeed Counter Functions

Versatile Pulse Control (CPU Units with Transistor Outputs Only)

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.

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

16 built-in outputs (Functions assigned.)

2 pulse outputs 100 kHz

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 changed by the INI instruction), 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.

Page 41

Features and Main Functions Section 1-1

Triangular Control

If the amount of output pulses required for acceleration and 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.

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 trapezoidal acceleration and 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 and 4 for CPU Units with 14 I/O points.

Note For each input point, a selection in the PLC Setup determines whether 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

By using quick-response inputs, built-in inputs up to a minimum input signal width of 50 ber of quick-response input points is 6 for CPU Units with 20, 30, or 40 I/O points and 4 for CPU Units with 14 I/O points.

µs can be read regardless of the cycle time. The maximum num-

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

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

Analog Settings

Changing Settings Using Analog Adjustment

Changing Settings Using External Analog Setting Inputs

By adjusting the analog adjuster with a Phillips screwdriver, the value in the Auxiliary Area can be changed to any value between 0 and 255. This makes it easy to change set values such as timers and counters without Programming Devices.

A642

Example: The production quantity could be changed by

changing the counter set value from 100 to 150.

Turning the control on the CP1H changes the PV in A642 between 0000 and 0255 (00 and FF hex).

External analog values of 0 to 10 V (resolution: 256) 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 particularly high degree of accuracy, such as for example, a setting based on changes in outdoor temperatures or potentiometer inputs.

When a voltage (0 to 10 V) is input from a device such as a potentiometer to the external analog setting input, the PV in A643 is refreshed between 0000 and 0100 hex (0 to 256).

• When a CP1L CPU Unit is used, the baud rate is automatically detected by the Support Software.

A standard protocol for host computers with either 1: 1 or 1: N connections.

• Slower than the peripheral bus mode.

• Allows modem or optical adapter connections, or longdistance or 1: N connections using RS-422A/485.

Features CPU Unit setting method

Turn ON pins SW4 (Serial Port

1) and SW5 (Serial Port 2) on the DIP switch on the front panel of the CPU Unit. These settings enable connection by peripheral bus regardless of the serial port settings in the PLC Setup.

Turn OFF pins SW4 (Serial Port

1) and SW5 (Serial Port 2) on the DIP switch on the front panel of the CPU Unit.

The mode will then be determined by the serial port settings in the PLC Setup. The default settings are for Host Link with a baud rate of 9,600 bits/s, 1 start bit, data length of 7 bits, even parity, and 2 stop bits.

Note When a Serial Communications Option Board is mounted in Option Board

Function Blocks Section 1-5

1-5 Function Blocks

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

1-5-1 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.

1-5-2 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 standardized function blocks reduces the time required for programming/debugging, reduces coding errors, and makes programs easier to understand.

Structured Programming

Easy-to-read “Block Box” Design

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 reading the program and no 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 addresses in 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 reading 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 are for a cold start at room temperature for an AC pow-

er supply, and for a cold start for a DC power supply.

• A thermistor (with low-temperature current suppression characteristics) is used in the inrush current control circuitry for the AC power supply. The thermistor will not be sufficiently cooled if the ambient temperature is high or 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.

• 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 breakers for external circuits.

(2) Use the external power supply to power input devices. Do not use it to

drive output devices.

(3) 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.

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

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.

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

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.

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

the Memory Cassette or from the built-in flash memory to the Memory Cassette.

Page 97

CP1L 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 Manual.

Page 98

CP1L CPU Unit Operation Section 2-3

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.

Remote Network Table

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 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 CX-Programmer or PT is used to transfer or edit data, edit the program 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 memory 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.

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

flash memory is being written or the Memory Cassette is being accessed.

Page 99

CP1L CPU Unit Operation Section 2-3

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-

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.
