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.

The Unstoppable Counter: Why IEC 61499's ECTU Guarantees Safe, Event-Driven Control (and Never Overflows)

Source: IEC 61499.

Master safe, event-driven control! Learn how the IEC 61499 E_CTU (Event-driven up counter) Function Block guarantees reliability. We explain how its Execution Control Chart (ECC) uses a tight guard condition (CU [CV<65535]) on the unsigned integer (UINT) CV to prevent overflows beyond the maximum value of 65535. Essential listening for robust Industrial-Process Measurement and Control Systems (IPMCSs).
