Industrial control system architecture for real-time simulation and process control

Multi-purpose dynamic simulation and run-time industrial or process control (MPDSC) system or platform 10 of an industrial process plant. The MPDSC comprises a process control system including one or more control loops operating to control an industrial process during run-time operations of the industrial process plant. Each control loop of the one or more control loops includes a respective field device disposed in physical environment 15 of the industrial process plant and a respective process control device disposed in virtual environment 12 of the industrial process plant. Each control loop utilizes input/output (I/O) switch 25 to deliver respective abstracted I/O data within each control loop. Each of the I/O switch and the respective process control device includes respective publish/subscribe layer 35, 42, 32 via which the respective abstracted I/O data is delivered within each process control loop.
