(a) Overhead time at execution of interrupt and fixed scan execution type programs
When calculating instruction execution time, add the overhead time given in the following table to the
instruction execution time, which is described in (4).
Two kinds of overhead time (pre-start and program-end) need to be added to interrupt programs.

connected)
*1: Indicates the value when the QI60 is mounted on the slot 0 of the main base unit.
*2: When any extension base unit is connected, the Q160 cannot be used. The values in the above list indicate overhead time for interrupt
processing from an intelligent function module.
