10.7.2 Application
Selector mini switch (VSGGIO) function is a multipurpose function used in the
configuration tool in PCM600 for a variety of applications, as a general purpose
switch. VSGGIO can be used for both acquiring an external switch position (through
the IPOS1 and the IPOS2 inputs) and represent it through the single line diagram
symbols (or use it in the configuration through the outputs POS1 and POS2) as well
as, a command function (controlled by the PSTO input), giving switching commands
through the CMDPOS12 and CMDPOS21 outputs.
The output POSITION is an integer output, showing the actual position as an integer
number 0 – 3.
An example where VSGGIO is configured to switch Autorecloser on–off from a
button symbol on the local HMI is shown in
figure 98. The I and O buttons on the local
HMI are normally used for on–off operations of the circuit breaker.

10.7.3 Setting guidelines
Selector mini switch (VSGGIO) function can generate pulsed or steady commands
(by setting the Mode parameter). When pulsed commands are generated, the length of
the pulse can be set using the tPulse parameter. Also, being accessible on the single
line diagram (SLD), this function block has two control modes (settable through
CtlModel): Dir Norm and SBO Enh.
