 Replacing a Unit
1
Turn OFF the I/O power supply of the I/O Unit being replaced.
2
Release the locks on the front of the I/O Unit that must be replaced and remove the
terminal block. The wiring can remain connected.
3
Remove the main block of the SmartSlice I/O Unit and replace it with a new I/O Unit of the
same type.
4
Mount the terminal block that was removed in step 2 and latch the hook that was
released.
5
Turn ON the I/O power supply.
Precautions for Correct Use
• When a Unit withdraws from I/O communication during replacement, the corresponding
SmartSlice I/O Unit Communication Withdrawn Flag will go ON and the EtherCAT
Communication Unit’s TS indicator will flash red.
• Before using the automatic restore function, the preparation for automatic restoration (creating
backup data and turning ON DIP switch 3) must be completed. See 5-2-8 Automatic Device
Restore Function (3 | ADR) for details.
• Always turn OFF the I/O Unit’s I/O power supply before replacement in order to prevent false
output signals, false input signals, and electrical shocks. In addition, if external power is
supplied to the terminal block for a Unit such as a Relay Output Unit, turn OFF that power
supply before replacing the Unit.
• Only replace one I/O Unit at a time.
• Always replace the I/O Unit with the same model of I/O Unit. If a Unit is replaced with a
different model, there may be unexpected outputs and the restore operation may not be
completed properly.
• If the base block is faulty or damaged, turn OFF the power supply and replace the entire Unit.
Even in this case, the I/O Unit’s parameter data will be restored automatically if the automatic
restore function is enabled when the power is turned ON.
