CP1E CPU Unit Hardware User’s Manual(W479)

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

Doing so may result in electric shock.

Do not touch any of the terminals or terminal bl ocks while the power is being
supplied.

Doing so may result in electric shock.

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. 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 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-VDC output (service power supply to the PLC) is overloaded or short­circuited, 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.

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.

Do not apply the voltage/current outside the specified range to this unit.
It may cause a malfunction or fire.

WARNING

17

CP1E CPU Unit Hardware User’s Manual(W479)

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(S)-type CPU Unit or with an N/NA(S)-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.

Tighten the screws on the terminal block of the AC power supply section to the
torque specified in the user’s manual.

The loose screws may result in burning or malfunction.

Do not touch the power supply section when po wer is being supplied or imme­diately after the power supply is turned OFF.

The power supply section and I/O terminal blocks will be hot and you may be burned.

CautionCaution

18

CP1E CPU Unit Hardware User’s Manual(W479)

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

A wrong connection may cause malfunction of the system.

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.

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 (S)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.

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.

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 o n 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 tur ned OFF and a mem ory er ror
will occur the next time the power supply is turned ON.

• With a CP1E CPU Unit, data memo ry 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 ind icato r is lit. If the power is tur ned O FF
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 U nit for at leas t 30 minute s and t hen com ­plete battery replacement within 5 minutes. Memory data may be c orrupted if this pre caution is
not observed.

• The equipment may operate unexpectedly if inapprop riate param eters are set. Even if the appro­priate parameters are s et, confirm th at equipment will no t be adversely affected before transfer­ring the parameters to the CPU Unit.

• 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.

• Do not drop the Unit or subject the Unit to unusual vibration and shock. Do so may result in failure
or fire.

• Confirm that no a dverse 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.

22

CP1E CPU Unit Hardware User’s Manual(W479)

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

result in malfunction or burn in g.

• Do not touch the Ex pa nsi on I/O Un it Conn ecting Cable while the power is being su ppl ie d i n o rder
to prevent malfunction due to static electricity.

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

• When transpor ting or stor ing Units or Board, st atic electric ity can destroy LSIs or ICs. Cover the

PCBs with a conductive material and maintain the specified storage temperature.

• Do not touch circuit boards or the compon ents mo unted to the m with your bare hand s. There are
sharp leads and other parts on the boards that may cause injury if handled improperly.

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

• Never short-circuit the positi ve and negative terminals o f a batter y or charge, disassemble, heat ,

or incinerate the batter y. Do not subject the battery to stron g shocks or deform the battery by
applying pressure. Doin g any of these may result in leakage, rupture, heat gen eration, or ignit ion
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.

• Dispose of the product and batteries according to local ordinances as they apply.

• UL standards require that o nly an experienced enginee r can replace the batt ery. Make sure that

an experienced engineer i s in charge of battery replacemen t. Follow the procedure for batter y
replacement given in this manual.

• The following precaution must be di splayed on all products tha t contain a li thium pr imary batter y

z External Circuit s

• Always configure the external circuits to turn ON power to the PLC before turning ON power to the

control system. If th e PLC power supply is tur ned ON after the control power supply, temporary
errors may result in control syste m sign als beca use the output ter mi nals 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 intern al circuit failures, which c an occur in rel ays, 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 dangerou s condit ions 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.)
