We are testing OPC COM communication reliability. Igntition Gateway was connected to remote OPC Server DA2 (PLC vendor’s OPC Server DA2 directly in PLC - connected by specifying CLSID in Configuration), we could see live tags (simulated integers), changing their values in Designer.
If we switch off the PLC, OPC Connection gets into Faulted status. How to ensure that after switching the PLC on, the Ignition Gateway reconnects automatically?
We should ensure total reliability of reconnection after any PLC manipulation (switch off/on, disconnect/reconnect Ethernet cable, downloading new version of PLC project, resetting PLC) without any operator manipulations…
