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.
IPOS1 IPOS2 Name of displayed string Default string value
0 0 PosUndefined P00

10.4.2 Functionality
The IEC 61850 generic communication I/O functions (DPGGIO) function block is
used to send double indications to other systems or equipment in the substation. It is
especially used in the interlocking and reservation station-wide logics.
