Function description
Logic rotating switch for function
selection and LHMI presentation
13.6.2 Application
The logic rotating switch for function selection and LHMI presentation function (SLGAPC) (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.
SLGAPC function block has two operating inputs (UP and DOWN), one blocking input (BLOCK) and
one operator position input (PSTO).
SLGAPC can be activated both from the local HMI and from external sources (switches), via the IED
binary inputs. It also allows the operation from remote (like the station computer). SWPOSN is an
integer value output, giving the actual output number. Since the number of positions of the switch
can be established by settings (see below), one must be careful in coordinating the settings with
the configuration (if one sets the number of positions to x in settings – for example, there will be
only the first x outputs available from the block in the configuration). Also the frequency of the (UP
or DOWN) pulses should be lower than the setting
From the local HMI, the selector switch can be operated from Single-line diagram (SLD).
13.6.3 Setting guidelines
The following settings are available for the Logic rotating switch for function selection and LHMI
presentation (SLGAPC) function:
Operation : Sets the operation of the function Enabled or Disabled .
NrPos : Sets the number of positions in the switch (max. 32).
OutType : Steady or Pulsed .
tPulse : In case of a pulsed output, it gives the length of the pulse (in seconds).
tDelay : The delay between the UP or DOWN activation signal positive front and the output
activation.
