Thanks for that. I'm glad it wasn't me doing something wrong. I'll try to get a response out of Matrikon, but as you say, I'm unlikely to end up using that server anyway.

I have checked the Matrikon OPC Server for Simulation and Testing with other OPC client (Softing), and there is the same issue. It appears that this server ignores the Percent Deadband. As such you'd have to resolve it with Matrikon (I can provide further facts to prove the claim if needed), or filter the notifications in your code.
I think that it is unlikely that you'll use this server in a real application anyway, however.

Hello
I have two simulation servers on my machine: one from OPC Labs and one from Matrikon. I can subscribe to both very nicely from my VBA application, but the "PercentDeadband" setting in my "SubscribeMultipleItems" doesn't seem to affect the Matrikon server at all. Any ideas?
