10.1.2 Time required for each processing included in scan time
(a) Overhead time at execution of interrupt program/fixed scan execution type
Note10.3
program Note3
The interrupt program/fixed scan execution type program includes overhead time.
Also, the interrupt program includes pre-start overhead time and program-end
overhead time.
When calculating the instruction execution time, add the following overhead time
to the above instruction execution time.

Table10.5 Overhead time of fixed scan execution type program
CPU module
Since the Basic model QCPU cannot use fixed scan execution type programs, it is not necessary
to be conscious of the overhead time of the fixed scan execution type program.
