DEVICE EXPLANATION
10.6.4 Switching scan/low speed exec. to Interrupt/fixed scan exec.Note19
The CPU module performs the following processing when switching between a scan/
low speed execution type program and an interrupt/fixed scan execution type
program.
• Index register value is saved (protected)/restored.
• File register block No. is saved (protected)/restored.
(1) Save (protection)/restoration setting
For the index register, when not writing date to index registers check by using an
interrupt program/fixed scan execution type program, the "High speed execution"
check box in the "Interrupt program/Fixed scan program setting" section at the "PLC
system" tab screen in the "(PLC) Parameter" dialog box. This will switch between
programs quickly.
