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

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

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

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

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

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

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

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

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

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

!Caution Confirm safety at the destination node before changing or transferring to

another node the contents of a program, the PLC Setup, I/O tables, I/O mem­ory, or parameters. Changing or transferring any of these without confirming
safety may result in injury.

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

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

Ω or less when installing the Units. Not

connecting to a ground of 100

Ω or less may result in electric shock.

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

• Mounting or dismounting Power Supply Units, I/O Units, CPU Units,
Memory Packs, or Master Units.

• Assembling the Units.

• Setting DIP switches or rotary switches.

• Connecting cables or wiring the system.

• Connecting or disconnecting the connectors.

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

the EtherNet/IP Unit or the system, or could damage the Ethernet Unit.
Always heed these precautions.

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

Application Precautions 5

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

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

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

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

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

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

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

• Observe the following precautions when wiring the communications
cable.

• Separate the communications cables from the power lines or high-ten­sion lines.

• Do not bend the communications cables past their natural bending ra­dius.

• Do not pull on the communications cables.

• Do not place heavy objects on top of the communications cables.

• Always lay communications cable inside ducts.

• Use appropriate communications cables.

• Make sure that the terminal blocks, expansion cable connectors, and
other items with locking devices are locked in place.

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

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

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

• Check the user program (ladder program and other programs) and
parameters for proper execution before actually running it on the Unit. Not
checking the program may result in 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.

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

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

• After replacing Units, resume operation only after transferring to the new
CPU Unit and/or Special I/O Units the contents of the DM Area, HR Area,
programs, parameters, and other data required for resuming operation.
Not doing so may result in an unexpected operation.

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

Conformance to EC Directives 6

• When transporting the Unit, use special packing boxes and protect it from
being exposed to excessive vibration or impacts during transportation.

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

• When the EtherNet/IP Unit's settings (IP address or tag data link settings)
are transferred from a Programming Device, all of the destination Ether­Net/IP Units (nodes) will be reset in order to enable the transferred set­tings. Transfer settings to the EtherNet/IP Units only after verifying that
restarting the Units will not cause any problems in the system.

• If a repeater hub is used for EtherNet/IP tag data links (cyclic communica­tions), the network's communications load will increase, data collisions
will occur frequently, and stable communications will be impossible.
Always use a switching hub when using tag data links in the network.

• Before resetting a CPU Bus Unit or Special I/O Unit, always verify that
restart the Unit will not cause any problems in the system.

6 Conformance to EC Directives

6-1 Applicable Directives

•EMC Directives

• Low Voltage Directive

6-2 Concepts

EMC Directives

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

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

Note Applicable EMS (Electromagnetic Susceptibility) and EMI (Electromagnetic

Interference) Standards in the EMC (Electromagnetic Compatibility) stan­dards are as follows:

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).
