We already have UA on the 1500s. Corporate heard Sparkplug. I can run both and I will hate myself. For read-only KPIs, what did you standardize, and what did you tell the cloud team they don't get?

MQTT Sparkplug vs OPC UA for a hall dashboard — pick one and why

UA in the cell. MQTT at the edge, outbound, Sparkplug if you already have the broker discipline. Don't put a second client on the PLC. Cloud gets a tag contract, not a subnet. Two protocols on the controller is how a scan dies on a Tuesday.
