Hi Experts
I am working on a project, which involves S7-1516 3PN/DP(has a limit of 20K tags) and Ignition 8.1, using OPC-UA having almost 19K tags. I am using optimised DBs & UDTs in TIA and UDTs as well in ignition perspective. The PLC scan time is around 200ms. Once a cmd is given from SCADA session, the plc action is instant but the scada take almost 5 to 30s to update the status. Any suggestions please that might help me minimizing this comms lag. Thanks
