Automatic Restore Function
Function Overview
38
The backup function records the parameter data of all SmartSlice I/O Units
connected to the PROFIBUS Communication Unit. The parameter data
recorded in the Communication Unit can be restored to the SmartSlice I/O
Units later with the automatic restore function when a SmartSlice I/O Unit has
been replaced.
Power ON
Turn DIP switch 4 ON, OFF,
and then ON again while the
power is ON and DIP switch 1
is ON.
1. Verify that the power is ON, DIP switch 1 (REGS) is ON, and all of the
SmartSlice I/O Units are participating in I/O communication.
2. Turn DIP switch 4 (BACK) ON, then OFF, and then ON again within 3 s to
start the back up.
3. While the data is being backed up, the PROFIBUS Communication Unit's
TS indicator will flash green every 0.5 s. The TS indicator will stop flashing
(not lit) when the backup is completed. If the restore operation fails, the TS
indicator will be lit red for 2 s.
1. Do not turn OFF the power supply or reset the Configurator while data is
being backed up. The data will not be backed up properly if the power is
turned OFF.
2. The backup data will be erased along with the registered I/O configuration
table if DIP switch pin 1 (REGS) is turned OFF.
3. Backing up the parameter data is recommended to allow easy replace-
ment of faulty Units in the future.
When a SmartSlice I/O Unit has been replaced, this function will automatically
download (restore) SmartSlice I/O Unit parameter data that was previously
backed up in the PROFIBUS Communication Unit. The following conditions
are required to execute the automatic restore function:
• DIP switch 1 (REGS) was ON when the power was turned ON, and the
registered table is therefore enabled.
• DIP switch 3 (ADR) was ON when the power was turned ON, and the
automatic restore function is therefore enabled.
• Parameter data has been backed up in the PROFIBUS Communication
Unit.
