The following timing chart shows the CPU Unit power OFF operation in more
detail.
Power OFF Detection Time
The time it takes to detect power OFF after the power supply falls below 85%
of the rated voltage.
Power OFF Detection Delay Time
The delay time after power OFF is detected until it is confirmed. This can be
set in the PLC Setup within a range from 0 to 10 ms. (The default is 0 ms.)
Power Holding Time
The maximum amount of time (fixed at 10 ms) that 5 V will be held internally
after power shuts OFF.
