Basic
Since the Basic model QCPU cannot use local devices, it is not necessary to be conscious of the
processing time described on this page.
Note10.8
Note10.8
When local devices are used, the following processing time shown in Table10.17 is
required.

(a) Scan time increased when local devices in subroutine program are made
available
When SM776 (setting of whether local devices are usable or not when the
subroutine program is called) is turned ON to make the local devices in the
subroutine program available, the scan time increases per call by the time
indicated in Table10.18 and Table10.19.
