(c) When low-speed execution type programs were not processed within the remaining
time in each constant scan or the low-speed program execution time
Program execution is stopped and the rest of the program is executed in the next scan.
(d) Low-speed END processing
When all the low-speed execution type programs are executed, the CPU module performs low-speed END
processing.
Low-speed END processing includes the following.
• Setting of the special relay and special register for low-speed execution type programs
*1
• Online change of low-speed execution type programs
• Measurement of low-speed scan time
• Reset of a watchdog timer for low-speed execution type programs
If SM330 is on and there is still a remaining time in a constant scan, the CPU module reexecutes the first low-
speed execution type program after the low-speed END processing.
*1: The special relay and special register for low-speed execution type programs are as follows.
• SM330, SM404, SM405, SM510
• SD430, SD510, SD528 to SD535, SD544 to SD547
When low-speed execution type programs are executed, the constant scan may increase by the maximum processing time
of the instructions being executed + the low-speed END processing time.
Remark
For differences between low-speed END processing and END processing, refer to Figure 2.26.
