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: UascClientMessageHandler (org.eclipse.milo.opcua.stack.client.transport.uasc.UascClientMessageHandler) 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 fast reply!
I asked to my co-worker:
In the tag browser we see the tag and if we try to change something ( a bool for example) sometimes it work but really slow, but we can try to take some screen shot when it happen again.
How I can call the support? By opening a ticket or by other mean?
Thank you for the help
There are 2 ServiceFault responses, the first is in response to a request that was made before the capture started. The second is a WriteRequest that the server is failing to respond to within 60 seconds.
I’m not sure either of these would explain the stranger issues you mentioned seeing. I think you’ll have to call into support and let them take a look and get some logs.
Unfortunately an email ticket can take as long as 2 weeks to get a response right now. If it’s urgent you can call support instead and you’ll get helped immediately. The phone queue takes priority over the email queue.
If we ask to Ingition on the Server to ask the Tag from the function System.opc.read, we read without any issue, if we do the same on another PC, we have the issue.
I don’t think that the TANI is the issue.
We disable all the firewall.
Here the screenshot from today.
