Hello everyone. I’ve been reading through OPC-UA / UNS discussions for several years now, and I keep seeing strong arguments on all sides, but no real convergence on what is optimal. I can only assume this is confusing for end users, too.
I’ve started to consider that the reason for the disagrements have less to do with tribalism, sunk costs and other factors than starting from different assumptions about what is primary, what counts as explanation, and where authority should sit. I notice that these debates rarely make those assumptions explicit.
So the same debates repeat (UNS vs OPC UA, broker vs model, edge vs cloud), but don’t really resolve.
I’m curious to see if others see it the same way, or if I’m missing something.
I tried to think this through more carefully and make those starting assumptions explicit here. This is more aimed at IIoT architects, automation/controls/SCADA/MES engineers. Am I on/off target? Thanks in advance for any feedback.
