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).
