Lets assume you don't know anything about industrial protocols. You are also working for a very high profile and very technically inclined company. Your job is to figure out how to get data over a network interface using a specific standard port. The protocol in use is THE standard for information systems in the industry: opcua.

How much hand holding do you need?

I am actually shocked at the amount of technical ineptitude of the people we have interfaced with. How did they get in the door?

When I first started out in my industrial controls career I just read whatever manuals and websites I could find. Do people not do that anymore?

I want to scream: RTFM Mother Fucker!
