Instruction execution time in END processing
This is the processing time of the DUTY instruction in END processing.
The user timing clock (SM420 to SM424 and SM430 to SM434) specified with the DUTY instruction is turned
on/off during the END processing.

Instruction execution time
Instruction execution time is the time required for all instructions used in the program to be executed.
For the processing time required for each instruction, refer to the following.
MELSEC-Q/L Programming Manual (Common Instruction)
When calculating instruction execution time, add the overhead time given in the following tables. Two kinds of
overhead time (pre-start and program-end) need to be added to interrupt programs.
(a) Pre-start overhead time for interrupt programs
