Functionality
The logic rotating switch for function selection and LHMI presentation SLGAPC (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
