Function description
Generic communication function for
double point indication
12.8.2
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.
