Webb16 dec. 2024 · Scan time: A PLC program is generally executed repeatedly as long as the controlled system is running. The status of physical input points is copied to an area of memory accessible to the processor, sometimes called the “I/O Image Table”. The program is then run from its first instruction rung down to the last rung.

Webb6 jan. 2024 · However, my code has nothing exotic in it (see attachment). Also, the scan times are about 1/10 of the watchdog timer setting. We swapped out the processor and still had the problem about a week later. Anyway, at the risk of masking the problem (and at A-B's suggestion), I set the watchdog time value at the max value of 255 (x 10 msec). Webb26 feb. 2024 · 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 bit.
