Replacing a Unit
3-2-4 On-line replacement function
Function Overview
DIP switch 1 was ON when
power is turned ON and
DIP switch 3 is turned from
OFF to ON.
1 Create backup data in the Communication Unit with the backup function.
For details, see section 3-2-2 Backup function.
2 Turn ON DIP switch 3 (ADR).
1,2,3... 1 Turn OFF the SmartSlice I/O System's power supply and the I/O power
supply.
2 Release the locks on the front of the SmartSlice 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
SmartSlice I/O Unit of the same type.
4 Mount the terminal block that was removed in step 2 and latch the locks
that were released.
5 When the power is turned ON again, the Communication Unit will
automatically detect the Unit that was replaced and download the backup
data. The SmartSlice I/O Unit's TS indicator will indicate the results of the
restore operation.
• If the download was successful, the Unit will be reset automatically and
join I/O communication normally. The I/O Unit's TS indicator will be lit
green.
• If the download failed, the I/O Unit's TS indicator will flash red.
• If the connected Unit is the wrong model, the I/O Unit's TS indicator will
be lit red.
Note 1 Do not turn OFF the power supply or reset the PROFINET IO Communication Unit
while data is being restored. The data will not be restored properly if the power is
turned OFF.
2 When a SmartSlice I/O Unit has been replaced with the power ON and the new I/O
Unit joins I/O communication, the new Unit will be compared to the previous one
and the parameter data restore operation will start automatically. While data is being
restored, the PROFINET IO Communication Unit's TS indicator will flash green
every 0.5 second. The TS indicator will stop flashing (not lit) when the restore oper-
ation is completed. If the restore operation fails, the Automatic Restore Monitor Flag
(bit 13 of the Communication Unit status flags) will be turned ON and the Communi-
cation Unit's TS indicator will be lit red for 2 seconds.
When one of the SmartSlice I/O Units connected to the PROFINET IO
Communication Unit must be replaced, the Unit can be replaced without
turning OFF the power. The Units can be replaced on-line because the
SmartSlice I/O Units are made up of 3 blocks: the base block, main block, and
terminal block.

Parameter data is automatically restored only
to the replacement Unit (same unit number,
same model number, different serial number).
