Fig. 5−7 Cyclic Program Execution
When a positive edge of one of the special interface input interrupt sig
nals EI1.0−EI1.2 occurs, cyclic program execution is interrupted after
the current command has been executed, and another organizational
module, OM2, OM3, or OM4 with a fixed allocation to the interrupt input is
started. Interrupt input priority is EI1.0, EI1.1 and EI1.2.
In this organizational module, the user can program the desired re
sponse to the interrupt signal. Further interrupts are disabled, but can be
enabled using the PLC command IF". After interrupt signal processing,
cyclic program execution is resumed at the point of interruption.
