I have a simple flow in order to read values on a OPCUA serveur on a PLC:
I first test the OPCUA value with UAExpert and it works well:
it works with no security&certificate and anonymous.
Then i try to test it in node-red with the same configuration values:
But when i inject i have nothing in return, no error messages, just the status of OPCUA client in "Connecting"... I try with other values, that's the same. I access well the PLC because i tested it with a classic S7 node.
Some ideas ? Thanks in advance !
