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.
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.
