WebAs for each scan period the length of time depends on the number of PLC programs and the processor speed of the PLC, but in general, it is 2-5 mS for each kilo program, overall the average scan time takes 10 – 50 mS. How process scanning is done in PLC? If the PLC operates where the program is scanned, the output status will not change immediately. WebThe project consists of one continuous task and a periodic task with an interval of 2 ms, and a scan time of 1 ms. TS is set to 10%. There are 5 axes of motion, with a CUR of 5 ms, and about 2.5 ms of calculation time (½ ms per axis * 5 axes). The periodic task set to run at 2 ms was delayed by 0.5 ms due to the motion task running.
