You can make a Registration Table with the CX-Integrator to allocate
I/O. For each SmartSlice I/O Unit in the table, you can specify if the
Unit is installed or not. When you turn ON the power, the Communica-
tions Unit will do a check only for installed Units. The Units which are
not installed will have empty spaces in the I/O data for the CompoNet
Master Unit.

Use this mode to automatically detect SmartSlice I/O Units when the
power supply turns ON.
The CompoNet Communications Unit reads the setting of pin 2 when the Unit
power supply turns ON.
Use pin 3 to control the automatic restore function.

Unit will automatically restore the parameters to the SmartSlice I/O
Units.

is ON, the parameters of all the SmartSlice I/O Units will be backed up to the
CompoNet Communications Unit. While the parameters are being backed up,
the TS indicator will flash green each 0.5 s.
