Hi, we are having OPC UA issues in connecting PCS7 V9.0 SP3 with OpenPCS 7 V9.0 to Ignition. Ignition will be used to log about 15k tags. At the OPC server we get the ‘high watermark error’.
Does someone faced the same issue when connecting this amount of tags? In the Siemens manuals nothing is mentioned about a max OPC tag amount.
We have no issues on another PCS7 with 7k tags.
I know it's more a Siemens topic, but let's try.
