All Ethernet-based interfaces have a table available in the I/O manager that shows the status of each connection. Each line represents one connection.
The modules for which the connections exist are identified by name in the first column (left) grouped by IEC 61850 devices.
The telegram counter is a continuous counter that is incremented by one with each received telegram. The response time is the time that a device requires to answer a data request. In the case of cyclical transmission, this corresponds to the time to read the data. In the case of MMS reports or GOOSE events, this corresponds to the time between events. The data size is the net data size of the transmitted telegrams.
Click the <Reset counters> button to reset the error counters and the calculation of the response times.
Additional information is provided by the background color of the table rows:
