OK, so here’s the case:
In our Ignition OPC UA-server we have all the tags for all the PLCs in our factory.
Now we are to start delivering products to an neighbouring plant through a pipeline. This means that this neighbouring plant needs to monitor some tank levels, and control some valves at our plant using their SCADA-system (Wonderware InTouch).
The “perfect” way to solve this (in my mind) would be for them to access our OPC -server (we will establish ethernet communications / firewalling).
The problem is that we dont’t want them to access ALL of our tags, only the tags that they need access to.
Is there any practial way to solve this? Do we need additional software to solve this issue?
