Interrupt Pointer (I)

This device is used as a label located at the head of the interrupt program. This pointer can be used in all the programs being
executed.
Interrupt pointer (interrupt program label)
Setting the execution type of program to the event execution type eliminates the need to write (I) the
interrupt pointer. ( Page 107 Interrupt occurrence by the interrupt pointer (I))

Description
This is a pointer used for modules which have the interrupt function.
This interrupt pointer is used in fixed scan interrupts by the internal timer.
This fixed scan interrupt pointer is used in the inter-module synchronization
function.
This fixed scan interrupt pointer is used in the multiple CPU synchronization
function.
This interrupt pointer is used in fixed scan interrupts by the internal timer
and can be specified in a shorter interval than interrupt pointer numbers I28
to I31.
This is a pointer used for modules which have the interrupt function.
