FB_[IEDName]Gse

This function block connects a network adapter of the TwinCAT control computer with the GOOSE control blocks in the data model and controls the execution of these control blocks.

To be able to use GOOSE communication, the real-time network adapter must be commissioned and linked. This is explained in RT Ethernet adapter configuration.
