Note It is recommended to use the features that are made available by DIP switches 1, 3 and
4 (as discussed on the next page).
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 PROFINET IO Communication Unit as a registered table.
If DIP switch 1 is ON when the Unit's power is turned ON, the actual
SmartSlice I/O Unit configuration at start-up is automatically compared to the
registered table. Any SmartSlice I/O Unit that does not match the registered
table will not participate in SmartSlice I/O communication.
