Discover the modular Anatomy of a Smart Machine (Industrial-Process Measurement and Control System or IPMCS). We dissect the physical architecture, starting with interconnected devices and their internal, independent resources (which contain a scheduling function). The software core is the application model, built as a function block network. Learn how the central software unit, the function block (FB), uses event-driven execution and the Execution Control Chart (ECC) to achieve robust and precise control.
