Hi all,

I am here (again) asking for help for a new problem that I have with the Prosys OPC UA simulator. The problem is this:

I am trying to conect with the OPC UA simualtor using a Python script and a client-server-based subscription. I mean, the script contacts with the simulator and it asks for a batch of data each X seconds (for example, 5 seconds) for a specific node (i.e. a variable). However, what I get is that, each 5 seconds, I got the last value of that variable, but not the previous ones. It doesn’t matter if during those 5 second the value has changed each 100 ms. I only get the most recent value. The other ones are… well, I don’t know where they are. Missing in action, I guess 🙂 Curiously, when I repeat the experiment using my own Python-written OPC UA server, everything works perfectly. But when I use the Prosys simulator, it doesn’t.

Do you any idea about what may be the reason behing this weird behaviour?

Best,
Luis
