I’m working on a project at the moment where I have a Siemens S7-1500 PLC hosting an OPC server that an ignition edge device reads tags from. This setup has been working for a few weeks now, but after a hard restart today we are are having an issue where the OPC server is disconnecting and reconnecting at about 2 minute intervals.
I manged to grab a screenshot of the logs when the OPC server faulted, but didn’t manage to fix the issue based of this.
Screenshots of the process I followed to setup the OPC client is below.
So far I have tried restarting the PLC and edge device numerous times, recreating the OPC server and client, rolling back the gateway to a previous working version, connecting the PLC directly to the edge device via an ethernet cable, setting up a new trial version of ignition as an OPC client (this managed to connect and fucntion correctly), tried on both ubuntu and windows versions of ignition edge, confirmed that the edge device could ping the PLC, temporarily disabled firwalls and securtiy.
If anyone had any suggestions of other things to try that would be greatly appreciated. Thanks in advance.
