The Unstoppable Counter: Why IEC 61499's ECTU Guarantees Safe, Event-Driven Control (and Never Overflows)
from IEC 61499: primer course EN presented by Franz Höpfinger · host Franz Höpfinger, Meisterschulen am Ostbahnhof, München, Landmaschinenmechanik
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).#IEC61499 #ECTU #FunctionBlocks #EventDrivenControl #ECC #GuardCondition #UINT #NoOverflow #IPMCS #ControlSystems #Automation #DistributedControl #Standardization #IECStandard
