Introduction

Thank you for purchasing a SYSMAC CP-series CP1E Programmable Controller.

This manual contains information required to use the CP1E. Read this manual completely and be sure you understand the contents before attempting to use the CP1E.

Intended Audience

This manual is intended for the following personnel, who must also have knowledge of electrical systems (an electrical engineer or the equivalent).

• Personnel in charge of installing FA systems

• Personnel in charge of designing FA systems

• Personnel in charge of managing FA systems and facilities

Applicable Products

 CP-series CP1E CPU Units

• Basic Models CP1E-ED-

A basic model of CPU Unit that support basic control applications using instructions such as basic, movement, arithmetic, and comparison instructions.

• Application Models CP1E-N/NAD- An application model of CPU Unit that supports connections to Programmable Terminals, inverters, and servo drives.

The CP Series is centered around the CP1H, CP1L, and CP1E CPU Units and is designed with the same basic architecture as the CS and CJ Series.

Always use CP-series Expansion Units and CP-series Expansion I/O Units when expanding I/O capacity. I/O words are allocated in the same way as for the CPM1A/CPM2A PLCs, i.e., using fixed areas for inputs and outputs.

CP1E CPU Unit Software User’s Manual(W480)

CautionCaution

Be sure to sufficiently confirm the safety at the destination when you transfer the program or I/O memory or perform procedures to change the I/O memory.

Devices connected to PLC outputs may incorrectly operate regardless of the operating mode of the CPU Unit.

With an E-type CPU Unit or with an N/NA-type CPU Unit without a Battery, the contents of the DM Area (D) *, Holding Area (H), the Counter Present Values (C), the status of Counter Completion Flags (C), and the status of bits in the Auxiliary Area (A) related to clock functions may be unstable when the power supply is turned ON.

*This does not apply to areas backed up to EEPROM using the DM backup function. If the DM backup function is being used, be sure to use one of the following methods

for initialization.

1. Clearing All Areas to All Zeros

Select the Clear Held Memory (HR/DM/CNT) to Zero Check Box in the Startup Data Read Area in the PLC Setup.

2. Clearing Specific Areas to All Zeros or Initializing to Specific Values Make the settings from a ladder program.

If the data is not initialized, the unit or device may operate unexpectedly because of unstable data.

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.

The DM Area (D), Holding Area (H), Counter Completion Flags (C), and Counter Present Values (C) will be held by the Battery if a Battery is mounted in a CP1EN/NAD- CPU Unit. When the battery voltage is low, however, I/O memory areas that are held (including the DM, Holding, and Counter Areas) will be unstable. The unit or device may operate unexpectedly because of unstable data.

Use the Battery Error Flag or other measures to stop outputs if external outputs are performed from a ladder program based on the contents of the DM Area or other I/O memory areas.

Sufficiently check safety if I/O bit status or present values are monitored in the Ladder Section Pane or present values are monitored in the Watch Pane.

If bits are set, reset, force-set, or force-reset by inadvertently pressing a shortcut key, devices connected to PLC outputs may operate incorrectly regardless of the operating mode.

CP1E CPU Unit Software User’s Manual(W480)

Caution

Program so that the memory area of the start address is not exceeded when using a word address or symbol for the offset.

For example, write the program so that processing is executed only when the indirect specification does not cause the final address to exceed the memory area by using an input comparison instruction or other instruction.

If an indirect specification causes the address to exceed the area of the start address, the system will access data in other area, and unexpected operation may occur.

Set the temperature range according to the type of temperature sensor connected to the Unit.

Temperature data will not be converted correctly if the temperature range does not match the sensor.

Do not set the temperature range to any values other than those for which temperature ranges are given in the following table.

An incorrect setting may cause operating errors.

CP1E CPU Unit Software User’s Manual(W480)

Precautions for Safe Use

Observe the following precautions when using a CP-series PLC.

 Handling

• To initialize the DM Area, back up the initial contents for the DM Area to backup memory using

one of the following methods.

• Set the number of words of the DM Area to be backed up starting with D0 in the Number of CH of DM for backup Box in the Startup Data Read Area.

• Include programming to back up specified words in the DM Area to built-in EEPROM by turning ON A751.15 (DM Backup Save Start Bit).

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

• The ladder program and parameter area data in the CP1E CPU Units are backed up in the built-in EEPROM backup 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 and a memory error will occur the next time the power supply is turned ON.

• With a CP1E CPU Unit, data memory can be backed up to the built-in EEPROM backup memory. The BKUP indicator will light on the front of the CPU Unit when backup is in progress. Do not turn OFF the power supply to the CPU Unit when the BKUP indicator is lit. If the power is turned OFF during a backup, the data will not be backed up and will not be transferred to the DM Area in RAM the next time the power supply is turned ON.

• Before replacing the battery, supply power to the CPU Unit for at least 30 minutes and then complete battery replacement within 5 minutes. Memory data may be corrupted if this precaution is not observed.

• The equipment may operate unexpectedly if inappropriate parameters are set. Even if the appropriate parameters are set, confirm that equipment will not be adversely affected before transferring the parameters to the CPU Unit.

• Before starting operation, confirm that the contents of the DM Area is correct.

• After replacing the CPU Unit, make sure that the required data for the DM Area, Holding Area, and

other memory areas has been transferred to the new CPU Unit before restarting operation.

• Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock.

• 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.

 External Circuits

• Always configure the external circuits to 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 terminals remain ON as a result of internal circuit failures, which can occur in relays, transistors, and other elements.

CP1E CPU Unit Software User’s Manual(W480)

• 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 instruction, all outputs from PLC will be turned OFF and only the internal output status in the CPU Unit will be maintained.)
