Ignition Version: 8.1.27 (b2023042509)
Ignition connected to 2 devices, 1 OPC and 1 OPC UA. Ignition bridge the communication and exchange couple of tag that include heartbeat signal that change every second. we got heartbeat fault on both side and ignition log show both heartbeat tags was not changing during that time. the log was generate with tag change gateway scrip and should be recorded for very change. the logs file on each device show their side are changing every second as expected. we have logs for the OPC connection and tag quality and show everything is ok. It is just look like the ignition OPC was dead for about 30 second and back again.
What could be possibly wrong? Thanks
