14.6.6 Operation principle
Selector mini switch (VSGAPC) function can be used for double purpose, in the same way as switch
controller (SCSWI) functions are used:
• for indication on the single line diagram (SLD). Position is received through the IPOS1 and
IPOS2 inputs and distributed in the configuration through the POS1 and POS2 outputs, or to
IEC 61850 through reporting, or GOOSE.
• for commands that are received via the local HMI or IEC 61850 and distributed in the
configuration through outputs CMDPOS12 and CMDPOS21.
The output CMDPOS12 is set when the function receives a CLOSE command from the local
HMI when the SLD is displayed and the object is chosen.
The output CMDPOS21 is set when the function receives an OPEN command from the local
HMI when the SLD is displayed and the object is chosen.
The PSTO input is connected to the Local remote switch to have a selection of operators place,
operation from local HMI (Local) or through IEC 61850 (Remote). An INTONE connection from
Fixed signal function block (FXDSIGN) will allow operation from local HMI.
As it can be seen, both indications and commands are done in double-bit representation, where a
combination of signals on both inputs/outputs generate the desired result.
The following table shows the relationship between IPOS1/IPOS2 inputs and the name of the
string that is shown on the SLD. The value of the strings are set in PST.

It is important for indication in the SLD that the a symbol is associated with a
controllable object, otherwise the symbol won't be displayed on the screen. A
symbol is created and configured in GDE tool in PCM600.
