If DIP switch 1 is turned from OFF to ON while the Unit's power is ON, the
existing SmartSlice I/O Unit configuration (connection order and I/O size) is
registered in the PROFIBUS Communication Unit as a registered table.
If DIP switch 1 is ON when the Unit's power is turned ON, the actual Smart-
Slice I/O Unit configuration at startup is automatically compared to the regis-
tered table. Any SmartSlice I/O Units that do not match the registered table
will not participate in SmartSlice I/O communication.
