Claim 0:
1. A method of controlling an industrial process of an industrial process plant, the method comprising:
during run-time operations of the industrial process plant, executing a process control loop of a process control system of the industrial process plant, the process control loop including a field device disposed in a physical environment of the industrial process plant, a process controller, and an I/O node communicatively disposed between the field device and the process controller, and the executing of the process control loop including:
receiving, by the process controller via the I/O node, data content generated by the field device corresponding to a physical function performed by the field device, the data content generated by the field device (i) received, in a real-time control protocol, by the I/O node in a first publication subscribed to by the I/O node, and (ii) provided, in the real-time control protocol, to the process controller via a second publication published by the I/O node; and
determining, by the process controller, a control signal based on the data content generated by the field device,

wherein an indication of the control signal is delivered from the process controller to the field device or to another process control device via a third publication published in the real-time control protocol, the third publication indicative of the control signal and subscribed to by the I/O node for delivery to the field device or to another process control device, to thereby control at least a portion of the industrial process.
