Intelligent Function Module Interrupt

This function outputs an interrupt request to the CPU module and starts an interrupt program when a signal is input to an SI
device terminal.
Operation
When an input signal event is detected or a comparison condition is satisfied, a signal is input from the "Output" terminal of a
multi function counter block to an SI device terminal. The interrupt program corresponding to the SI device terminal to which
the signal has been input is executed.
Setting method
To use the intelligent function module interrupt, intelligent function module interrupt pointers and a hardware logic are required
to be set in advance.
■Setting intelligent function module interrupt pointers
Set interrupt factors (SI) and interrupt pointers of the CPU module in the intelligent function module interrupt pointer setting.
