GOOSE (8-1) Publishers

Connection point

DirectionDescription
EnableFrom model to driverControls the transmission of GOOSE message. An input of 1 activates transmission and value of 0 disables it.
Data / Data Objects (DO) / Data Attributes (DA):From model to driverEvery basic attributes found in the GOOSE definition provides a connection point referenced by their DO and DA names.
FlagsFrom model to driver

simulation: This input controls directly the GOOSE Header field "test". If input value is TRUE, GOOSE message will be transmitted with test flag equal to TRUE informing to all subscribers that Object Input Data is the result of a testing.

ndsCom: This input controls directly the GOOSE Header field "needs commissioning".

ClockFrom model to driver

Sync: It is a binary value (0 or 1) that represents the synchronization state of the timestamp. If the timestamp is synchronized with an accurate external source such as a GPS, the value applied to this signal should be set 1 and otherwise it should be 0. This value will appear in each time qualify byte of the data frames to indicate the validity of the timestamp.

Epoch: Represents the number of seconds elapsed since first January 1970, commonly known as unix epoch time. It means that it has to increment at each second. The GOOSE Publisher uses this signal to timestamp the outgoing packets. The more accurate this epoch time input will be, the more accurate will be the timestamp of the outgoing packets.

Microseconds: Represents the microseconds count within the current second.

StatusFrom driver to model

stNum: This value is incremented, starting from 0, with every change of whichever of the objects contained within the GOOSE message.

sqNum: This value is incremented, starting from 0, with every GOOSE message received without any modification to its objects' value. If any change is detected for whichever of the objects this count is RESET to zero.
