27.13 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.
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))
Interrupt factors of the interrupt pointer numbers
The interrupt factors of the interrupt pointer numbers are indicated.
Interrupt factor Interrupt pointer number Description
Interrupt from module I0 to I15 This is a pointer used for modules which have the interrupt function.
Interrupt by the internal timer I28 to I31 This interrupt pointer is used in fixed scan interrupts by the internal timer.
Inter-module synchronous interrupt I44 This fixed scan interrupt pointer is used in the inter-module synchronization
function.
Multiple CPU synchronous interrupt I45 This fixed scan interrupt pointer is used in the multiple CPU synchronization
function.
High-speed internal timer interrupt 2 I48 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.
High-speed internal timer interrupt 1 I49
Interrupt from module I50 to I1023 This is a pointer used for modules which have the interrupt function.
