DIP Switches on the NIU

The 10-position DIP switch on the NIU module is used to set the Profibus address.
In addition, switch 8 can be used to select the operating mode of Profibus NIU
IC220PBI002. For model PBI001, the same switch specifies the error response of
the NIU.

For Module IC220PBI001: Behavior if a data error occurs in the station
(local bus error):
ON = data transmission is stopped after a number of attempts.
OFF = the station constantly attempts to start data transmission.
If DIP switch 8 is in the ON position, a POWER DOWN/POWER UP must
be executed on the NIU so that it will restart. There is no automatic
restart after the error has been removed.
Reserved, both switches must be in the OFF position.
