Hello everyone,

We having the following scenario of a system that has OPC server and we building OPC client to interface to it and on the other side we have a microserver (Controller) that we want to communicate with the OPC client to control the system. What is the best way to have the microservice controller to communicate with the OPC client? is RabbitMQ or any other broker an option?

Depends on what s/w is installed on the microcontroller already.

If you have an MQTT client that could make sense.

If you have an embedded UA server then that could work too.
