Company uses motion drives and inverters and uses OPC UA to test and expose PLC variables to higher systems. OPC UA is OS and language independent and already ubiquitous. OPC UA FX extends OPC UA down to sensors and drives and the controller-to-controller spec ships recently and runs over Time Sensitive Networking for deterministic timing aiming below millisecond latencies. It includes safety data exchange and process data; controller-to-device and device-to-device specs are still in progress.
