Timeout issue #690

Open archerixx opened 5 months ago

archerixx commented 5 months ago

After latest update, I am getting following error message: "Client node error on: error: [" error at active reading: Transaction has timed out ( timeout = 15000 ms , request = ReadRequest)"]"

This is example of my flow: opc_ua.json

Worked just fine before updates 2 weeks ago.

Hmm, I fixed partly your flow so it works now: image

Separated adding nodeIds and repeat readmultiple: OPCUA-ISSUE-690.json

OPC server was bugged, seems that timeout happens now only from time to time. It is probably server's fault.

Is there limit to how many requests at a time can be made towards one server?

mikakaraila commented 4 months ago

If your server is made with all features that specification contains then it should have diagnostics (UaExpert can show). And the latest specification contains also server limits.

Hi,

Could you make this error/warning as one that can be caught with "Catch" node ?

Currently it keeps popping in debug and console and I can't do anything with it, so it would be great to catch it with Node-red's Catch node (so I can report in my system as device state)

Thanks

Sorry, but the error comes from the node-opcua... I expect that I cannot catch it.
