5. When the power is turned ON again, the Communications Unit will auto-
matically detect the Unit that was replaced and download the backup data.

join I/O communications normally. The I/O Unit’s TS indicator will be lit

data is being restored. The data will not be restored properly if the power
is turned OFF or the Unit is reset.

fails, the Automatic Restore Monitor Flag (bit 13 of the Communications
Unit Status Flags) will be turned ON and the Communications Unit’s TS
indicator will be lit red for 2 s.

Online Replacement Function
Function Overview
When one of the Slice I/O Units connected to the Communications Unit must
be replaced, the Unit can be replaced without turning OFF the Slice Bus
Power. Any AC power supplied via the Slice I/O Terminal must always be
turned OFF before replacing a Unit.
The Units can be replaced online because the Slice I/O Units are made up of
3 blocks: the base block, main block, and terminal block. When replacing a
Slice I/O Unit, leave just the base block connected and replace the main
block. I/O communications will continue with the other I/O Units even while the
problem Unit is being removed and replaced.
Replacement Procedure
1,2,3...
1. Turn OFF the I/O power supply of the I/O Unit being replaced.
2. Release the hook on the front of the I/O Unit that you want to replace and
remove the terminal block. The wiring can remain connected.
3. Remove the main block of the Slice I/O Unit and replace it with a new I/O
Unit.
To keep the system online, leave the
communications block connected.
