Error BadNodeIdUnknown in UAExpert

Post by oumaima »

Hello everybody,

I´am trying to connect to KEPServerEX using UAExpert, I succeed to connect to the server.
I can access to all the parameters apart from the tags that i defined. I get the error "BadNodeIdUnknown" .
Do you have an idea why I get this error especially for tags ?

the self configured tags probably do not exist in the underlying PLC. You must configure the KepserverEX correctly, just creating tags is not enough, they must exist in the underlying PLC as well to come to life.
