Node-red-contrib-opcua frequently halts Node-Red machine

Hi node-red-contrib-opcua users,

I'm using the opcua client to read tags from an opc server. It works, but frequently, when there is some opc server problem, the opcua client node begins to send several error messages to the debug area, and the node-red machine stopped. Is there a way to disable the debug message error of the node?

Thanks,

Roberto Campos

You can use a "Catch" node to handle the errors on that OPCUA node.

Hi /hp_apcc,

Thanks for your attention. We solved the problem, changing the action in the OPC-UA node from READ to SUBSCRIBE. Then the tags are sent only when its value change, lowing the comunication frequency.

Best regards.

Roberto
