Function description
Logic rotating switch for function
selection and LHMI presentation
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 operating on pre-set values. Hardware switches are however
sources for maintenance issues, lower system reliability and an extended purchase
portfolio. The selector switch function eliminates all these problems.
