(2) Precautions
(a) When the SM776 is ON, the local device data can be read while the subroutine
program is called. Furthermore, the data will be escaped after performing the
RET instruction.
When the SM777 is ON, the local device data is read before performing the
interrupt program. The data will be escaped after performing the IRET
instruction.
Therefore, when SM776 and SM777 are ON, the scan time is extended by the
time below after the subroutine program/interrupt program is executed once.
(b) ON/OFF of SM776 and SM777 is set for each CPU module.
It cannot be set for each file.
(c) When ON/OFF of SM776 and SM777 is changed during execution of the
sequence program, the control is performed with the changed information.
