Note3
Basic 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.
Note11.3
(a) Overhead time at execution of interrupt program/fixed scan execution type
Note11.3
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.

* 1 : Indicates the value when the QI60 is mounted on slot 0 of the main base unit.
* 2 : The QI60 cannot be used when connecting to the extension base unit. The values in table show
the overhead time of processing interrupted from the intelligent function module.
