Codesys Communication Watchdog

I have 3 Groov EPIC PR1’s networked together over Starlink and wanted to use the xConnected parameter on the MMP Client function blocks to monitor for loss of communications between the sites. However, upon testing it appears that once the MMP Client has been connected to there is not continuous evaluation of the MMP connection.

Is there something like a watchdog timer or a connection parameter that is ready made or will I need to create a check for communication?

Thanks

According to 1465 OptoMMP protocol guide, OptoMMP can be wrapped in TCP or UDP. Have you configured the MMP Client for TCP and observed the same behavior? UDP is a connectionless protocol, so there is no connection to monitor.
