Logic rotating switch for function
selection and LHMI presentation

Functionality

The logic rotating switch for function selection and LHMI presentation SLGGIO (or
the selector switch function block) is used to get an enhanced selector switch
functionality compared to the one provided by a hardware selector switch. Hardware
selector switches are used extensively by utilities, in order to have different functions
operating on pre-set values. Hardware switches are however sources for maintenance
issues, lower system reliability and an extended purchase portfolio. The logic selector
switches eliminate all these problems.
