Unknown Value KEPServerEX #478

Open QuentinJ2S opened 7 years ago

QuentinJ2S commented 7 years ago

Hello everyone, I'm trying to connect a FreeOPCUA Server to the Kepware quick client.

My server works fine with UAExpert but Kepware is unable to read values. It can read tags name and type.

In quick client quality is bad and the value is reported as unknown in one menu and BAD VARTYPE in the other menu.

Does someone have an idee why Kepware is the only client that doesn't read properly my values ?

Thanks for your help

No idea, maybe search old bugs. I kinda remember that this client is very bad

I meet the same problem. How to solve it.

Hello, It was a long time ago but I remember adding try finally at some point and it made a difference on one of my issues.

try /my server code/ finally: server.close()

If doesn't work for you, I can dig up my old files.

tvvbbb commented 5 years ago

My code like this. But it doesn't work.

oroulet commented 5 years ago

usually the issue is that the client expects SourceTimestamp or ServerTimestamp or does not support one of these
