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.

WebbDo not use a lower RPI than you need. Usually an RPI of 10 ms or 20 ms is sufficient. Lowering the RPI will increase the load on every Ethernet component in the system, and beyond a certain point has no benefit. For example, if the RPI is lower than the scan time of the controlling PLC, then additional packets will not benefit the system. Webb17 juni 2016 · For those not familiar with PLCs, they are used in industrial automation and usually run with a program scan time of < 1 to 20 ms. (OP's 200 ms scan time would be considered very slow.) The short and preferably fixed scan time gives a predictable and repeatable response time to a change in inputs and timing of outputs. Figure 1.
