Good morning to everyone,
We are experiencing some issues with Ignition.
The behavior is this:
Ignition work propelly for about 3-4 hour, after that the tag browser and all the tag became unavailable.
The OPC (Tani OPC Server) still work and can read/write the tag.
The only code we had in the log is this for the moment:
No pending request with requestId=XXXXXX for ServiceFault
To solve the problem we have to disable and enable the Opc connection.
We are using Ignition 8.0.16 connected with Tani OPC-UA 1.25.15 (the latest version), PLC Siemens 1500.
We have another plant with the same configuration (Tani OPC) but with Rockwell and we don’t experience any issues.
For sure is not the Tani OPC, we optimize the comunication of the tag but no matter how we speed up the performance, it seem that after sometime the problem come back.
we try this to solve the problem:
Give more memory for the heap
Optimize the scan class
One time we found in quarantine the trusted certificate and we allow it.
It seems that the tag service became unavailable, the issues is really similar to this:
Thank you for the help
