We have an installation with a Siemens PLC, and use the internal OPC-UA server.
But every time we download an online change to the PLC, the OPC-UA server needs to restart, and we lose the connection between Ignition and the PLC for about 10 minutes.
There are around 22000 tags in our Ignition project, of which the majority is coming from that Siemens PLC. I hope that’s not too much, as Beckhoff is usually able to handle projects this size quite easily.
Does anyone know how to stop restarting the OPC-UA server when there’s no change to it, or how to speed up the reconnection time? 10 minutes is just too long.
