Vamp relay MMS and goose communication.
Have faced similar issue with Schneider IED's. The problem here is the Network load because of Goose. To circumvent this the min time and max time of Goose signals to be adjusted. Nomrally min time is 4ms. We had success by changing it to 20ms and max time to 1s. However we did this by splitting up signals into 2 Goose datasets. One for digital and other for analog. Analog signals were givren more time whereas digital were given less time sine they were used for Load shedding triggering.
