(g) Interrupt during END processing
When the constant scan is set and an interrupt factor occurs during the wait time
in the END processing, an interrupt program corresponding to the interrupt factor
is executed.
(5) Save and restoration of index register data and file register No.
When an interrupt program is executed by default of the CPU module, the index
register data and file register block No. are saved and restored at the time of switching
between the scan execution type program/low speed execution type program
Note3.12
and the interrupt program.( Section 10.6.4)Note12
(6) High speed execution setting and overhead time of interrupt program
When the "High speed execution" item for interrupt programs is checked on the PLC
system tab of PLC parameter in GX Developer, the index registers are neither saved
nor restored at the time of switching from the main routine program to the interrupt
program.
This reduces the overhead time of the interrupt program.( CHAPTER 11)
