Yeah, what I mean though, is that if this isn’t available via the CIP Read Tag service and is instead implemented by some proprietary or undocumented service, it’s unlikely we’ll be able to do it.
I’ll have to get a Wireshark capture of the traffic between FTView and a controller when I have some free time.
“Because these tags are not exposed via the FactoryTalk Gateway or RSLinx Classic OPC servers, they cannot be accessed through any third party OPC client.”
