14.7.6 Operation principle
SEMOD55861-5 v7
When receiving the input signals, DPGAPC sends the signals over IEC 61850-8-1 to the systems,
equipment or functions that requests and thus subscribes on these signals. 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.
Refer to Table
554 for the description of the input-output relationship in terms of the value and
the quality attributes.
