Procedure for Writing Program to CPU ModuleAppendicesIndex
1) Overhead time taken when local devices in interrupt program are made
available
Note11.4
Note5
When SM777 (setting of whether local devices in interrupt program are
enabled or disabled) is turned ON to make the local devices in the interrupt
program available, the following time is added to the overhead time in
Table11.6 and Table11.7.
The definition of n, N1, N2, and N3 in the following table is as follows:
• n: The number of local device points (Unit: k word)
• N1: The number of device types that specifed a local device
• N2: The number of word device points that specifed a local device
• N3: The number of bit device points that specified a local device
Note5

CPU module
Value added to pre-start overhead time of
interrupt program (Table11.3)
Value added to program-end overhead time of
interrupt program (Table11.4)

Basic
Note11.4
Since the Basic model QCPU cannot execute multiple programs, it is irrelevant to the difference
between global devices and local devices ( Section 10.14.1).
It is not necessary to be conscious of the overhead time of the fixed scan execution type
program.
