Interrupt Return (IRT)
When an Interrupt Return is executed in the interrupt routine, the
CPU will return to the point in the main body of the program from
which it was called. The Interrupt Return is programmed as the last
instruction in an interrupt routine and is a stand alone instruction
(no input contact on the rung).
Interrupt Return Conditional (IRTC)
The Interrupt Return Conditional instruction is a optional
instruction used with an input contact to implement a condtional
return from the interrupt routine. The Interrupt Return is required to
terminate the interrupt routine.
Enable Interrupts (ENI)
The Enable Interrupt instruction is programmed in the main body of
the application program (before the End instruction) to enable
hardware or software interrupts. Once the coil has been energized,
interrupts will be enabled until they are disabled by the Disable
Interrupt instruction.
Disable Interrupts (DISI)
The Disable Interrupt instruction is programmed in the main body of
the application program (before the End instruction) to disable both
hardware or software interrupts. Once the coil has been energized,
interrupts will be disabled until they are enabled by the Enable
Interrupt instruction.
