Doing a Check of the Restore Results
The TS indicator on the CompoNet Communications Unit flashes green dur-
ing the restore operation. The restore operation is completed when the TS
indicator stops flashing.
If the CompoNet Communications Unit restored the parameters, it will reset
the SmartSlice I/O Units automatically and the TS indicator on the CompoNet
Communications Unit will come ON in green.
If the CompoNet Communications Unit could not restore the parameters, the
TS indicator on the CompoNet Communications Unit will come ON in red for 2
seconds. The Automatic Restore Monitor Flag (bit 13 in the status word for the
CompoNet Communications Unit) will also turn ON.
If the new SmartSlice I/O Unit is not the same model as the previous Unit, the
TS indicator on the CompoNet Communications Unit will flash in red.

Replacing Units Online
You can replace a SmartSlice I/O Unit in the SmartSlice I/O Terminal without
turning OFF the Unit power supply.
A SmartSlice I/O Unit has a base block, main block, and terminal block. When
you replace a SmartSlice I/O Unit, do not replace the base block and replace
the other blocks.
Communications with the other SmartSlice I/O Units will continue while you
replace the SmartSlice I/O Unit.
If you back up the parameters, you can turn ON pin 3 (ADR) with pin 1
(REGS) or pin 2 (I/O) ON to automatically restore the parameters.
Refer to the
GRT1 Series SmartSlice I/O Units Operation Manual
(Cat. No.
W455) for information on how to replace SmartSlice I/O Units.
!WARNING
Turn OFF the I/O power supply to a SmartSlice I/O Unit before you replace it.
Incorrect inputs, incorrect outputs, or electrical shock can occur if you do not
turn OFF the I/O power supply. If there is external power to a terminal for a
Relay Output Slave, for example, turn OFF the external power before you
replace the SmartSlice I/O Unit.

Automatic Baud Rate Recognition
The CompoNet Communications Unit will automatically detect the baud rate
set in the CompoNet Master Unit and use it for communications with the Com-
poNet Master Unit.
• Replace only one SmartSlice I/O Unit at a time.
• Always replace a SmartSlice I/O Unit with a Unit of the same model number. If
you use a different model, incorrect outputs can occur or restoring the param-
eters will not be possible.
• If it is necessary to replace the base block, turn OFF the unit power supply
and the I/O power supplies and replace the full SmartSlice I/O Unit. You can
also use the Automatic Restore Function after you replace the full SmartSlice
I/O Unit.
