Unit Functions
Section 3-2
Preparing Data Restore
1,2,3... 1. Create backup data in the Communication Unit with the backup function.
For details, see
3-2-2 Backup Function
.
2. Turn ON DIP switch 3 (ADR).
Replacing a Unit
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 re-
placed 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 lock that
was released.
5. When the power is turned ON again, the Communication Unit will automat-
ically 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 op-
eration.
• 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 PROFIBUS Communication
Unit while data is being restored. The data will not be restored properly if
the power is turned OFF.
2. When an 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 previ-
ous one and the parameter data restore operation will start automatically.
While data is being restored, the PROFIBUS Communication Unit’s TS in-
dicator will flash green every 0.5 s. The TS indicator will stop flashing (not
lit) when the restore operation is completed. If the restore operation fails,
the Automatic Restore Monitor Flag (bit 13 of the Communication Unit sta-
tus flags) will be turned ON and the Communication Unit’s TS indicator will
be lit red for 2 s.

DIP switch 1 was ON when
power is turned ON and
DIP switch 3 is turned from
OFF to ON.
Parameter data is automatically restored only
to the replacement Unit (same unit number,
same model number, different serial number).
