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, where 0 = MidPos, 1 = Open, 2 = Closed and 3 = Error.
VSGAPC is provided with IEC61850 communication for the circuit breaker operation. It is
controlled from the SA system.

Application

Generic communication function for Double Point indication (DPGAPC) function block is used
to send double point position indication to other systems, equipment or functions in the
substation through IEC 61850-8-1 or other communication protocols. It is especially intended
to be used in the interlocking station-wide logics. To be able to get the signals into other
systems, equipment or functions, one must use other tools, described in the Engineering
manual, and define which function block in which systems, equipment or functions should
receive this information.
More specifically, DPGAPC function reports a combined double point position indication
output POSITION, by evaluating the value and the timestamp attributes of the inputs OPEN
and CLOSE, together with the logical input signal VALID.
When the input signal VALID is active, the values of the OPEN and CLOSE inputs determine the
two-bit integer value of the output POSITION. The timestamp of the output POSITION will have
the latest updated timestamp of the inputs OPEN and CLOSE.
When the input signal VALID is inactive, DPGAPC function forces the position to intermediated
state.
When the value of the input signal VALID changes, the timestamp of the output POSITION will
be updated as the time when DPGAPC function detects the change.
