10.6.2 Application
The logic rotating switch for function selection and LHMI presentation function
(SLGGIO) (or the selector switch function block, as it is also known) is used to get a
selector switch functionality similar with the one provided by a hardware multi-
position 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 extended
purchase portfolio. The virtual selector switches eliminate all these problems.
SLGGIO function block has two operating inputs (UP and DOWN), one blocking
input (BLOCK) and one operator position input (PSTO).
