Winstudio OPC UA with 4K vars

Hello

Hardware
PR4200.1-2B1-AA-000-NN-C1-NNNNNNNNNNNN-H with Indraworks 15v16.3 and winstudio Runtime 4K with COM
Corex X3, Apps: Systemapps 1.20, PLC 1.20, OPCUAServer 1.20 and more

I feel that the OPC communication is quite unstable. It takes multiple restarts of Winstudio Runtimeapp before all vars is updating/communicating with Server. After a while it seems that some vars stops to communicate.

Using 3,5k vars in 17 driversheets.
Varcount i sheets: Min:10 Max:400
Publishrates: Min:200ms Max:1s
No Sequrity

 

Winstudio settings
Communication - UPCUA - Serverconfiguration - Advanced

Setting of Driversheets

PLC symbolefile settings




The symbolfile is quite big. Using attributes to make the symbolefile. I have lots of vars that i can remove from the Symbolfile. 

OPC server app 1.20 settings

CPULoad on core2 (Where the server runs) 70-80%.

In lack of knowledge how OPC-UA works i need help with these settings to accoplish a good communication between HMI and PLC. Especially Server settings.

Thank you.

 

*Update: Added Logbook

Hello,

The parameters on the WinStudio side seems to be ok. It is a good idea just to trace one of the driver sheets. You can use therefore an Integer tag for Status and a string Tag for the message. Every value (status tag) not equal 1 is an error message.

in addition to that you should trace the communication with remote Logwin.
