Using a High-Speed Counter’s Hardware Interrupt to Peripherally Write to an Output on a Siemens 1200 PLC

The built-in high-speed counters on Siemens PLCs are very useful for applications in which a machine needs to move material a specified distance. In these instances, the scan time of the program can add inconsistency to this distance. Reduce this inconsistency by using a built-in hardware interrupt associated with high-speed counters. Reduce the variance due to a program's scan time by passing a reference point to the high-speed counter and peripherally writing to the desired output ...
