No, I would dock them to the middleware using whatever protocol they
run. That is one of the key advantages of a proper middleware over OPC,
i.e. an abstraction of the hardware.
With OPC/MQTT approach you must wait until the vendor of the encoder
will write an OPC/MQTT server for you. He might do it or decide in favor
of something else ModBus, ProfiNET, CAN etc. Vendors have limited
resources and even more limited software development competence to
expect them to offer the exactly "standard" you consider standard.
