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.
