3 Safety Precautions

!WARNING Never attempt to disassemble any Units while power is being supplied. Doing

so may result in serious electrical shock or electrocution.

!WARNING Make sure that the current or voltage input to the Unit is within the specified

ranges. Using a current or voltage outside of the specified range may result in
damage or fire.

!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.

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

2. 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. Ex­ternal safety measures must be provided to ensure safety in the system in
case an error or FALS instruction causes all outputs to be turned OFF.

3. The PLC outputs may remain ON or OFF due to fusing or burning of the
output relay contacts or destruction of the output transistors. External safe­ty measures must be provided to ensure safety in the system in case the
outputs fail and remain ON or OFF.

4. 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. External safety measures must be provided to ensure safety
in the system in case of a power supply problem that causes outputs to be
turned OFF.

!WARNING The PLC’s CPU Unit continues I/O refreshing even when the program is not

being executed (in PROGRAM mode). Before proceeding with any of the fol­lowing operations, verify that it is safe to do so in case the operation changes
the status of output bits allocated to Output Units or the data allocated to Spe­cial I/O Units or CPU Bus Units. It is possible for a load connected to an Out­put Unit, Special I/O Unit, or CPU Bus Unit to operate unexpectedly.

• Using a Programming Device (Support Software in a personal computer)
to transfer data to the CPU Unit’s I/O memory area.

• Using a Programming Device to change present values

• Using a Programming Device to force-set or force-reset bits

• Transferring an I/O memory file to the CPU Unit from EM file memory

• Transferring I/O memory from another PLC or host computer in the net­work

xviii

!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.

Safety Precautions 3

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

gram, PLC Setup, I/O table, or I/O memory in another node. Changing data in
another node without confirming safety may cause unexpected operation and
result in injury.

1-2-3 Types of Slaves

The following classifications are used for DeviceNet Slaves.
For more details on the General-purpose Slaves, Environment-resistive

Slaves, and Special Slaves, refer to the DeviceNet DRT1 Series Slaves Oper-

ation Manual (W347) for DRT1-series Slaves and the DeviceNet DRT2 Series
Slaves Operation Manual (W404) for DRT2-series Slaves.

Refer to the DeviceNet MULTIPLE I/O TERMINAL Operation Manual (W348)
for more details on the MULTIPLE I/O TERMINAL Slaves.

General-purpose Slaves Slaves with I/O functions for 32 or fewer inputs and 32 or fewer outputs.

Environment-resistive
Slaves

Slave with I/O functions for I/O that uses a round, waterproof connector con­nected to a communications cable.

Special Slaves Slaves with more than 32 inputs or 32 outputs or Slaves with functions other

than I/O.

MULTIPLE I/O TERMINALs These are high-density I/O Block Slaves.
