(2) The CompoNet Communications Unit will clear the backup data if you
change the operating mode.
The CompoNet Communications Unit will clear the backup data if you
back up the parameters with pin 2 (I/O) ON (Software I/O Allocation
Mode) and then make the Registration Table from the CX-Integrator.
After you replace a SmartSlice I/O Unit, you can use the Automatic Restore
Function to automatically download the parameters in the CompoNet Com-
munications Unit to the SmartSlice I/O Units.

Turn ON pin 3 when
pin 1 or pin 2 is ON.
The CompoNet Communications
Unit will automatically download
the parameters to the new Unit.
These conditions are necessary to automatically restore the parameters. Do a
check of these conditions before you restore the parameters.
• There must be backup data in the CompoNet Communications Unit.
• Pin 1 (REGS) or pin 2 (I/O) on the DIP switch on the CompoNet Commu-
nications Unit must be ON.
• The new SmartSlice I/O Unit must have the same unit number and model
number as the previous SmartSlice I/O Unit, but a different serial number.
1. Turn ON pin 3 (ADR) on the CompoNet Communications Unit to enable the
Automatic Restore Function.
2. Turn OFF the I/O power supply and replace the SmartSlice I/O Unit.
Refer to the GRT1 Series SmartSlice I/O Units Operation Manual (Cat. No.
W455) for information on how to replace SmartSlice I/O Units.
The CompoNet Communications Unit will detect the SmartSlice I/O Unit that
you replaced and it will download the parameters to it.
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.
• Do not turn OFF the power supply or reset the CompoNet Communications
Unit from the CX-Integrator during the restore operation. The restored data
will not be correct.
3. Turn ON the I/O power supply.
