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
