5.4.7.3
Identification of an NCK event in the PLC program
A hardware interrupt OB should be assigned to the event-driven signal exchange from NCK to
PLC that exclusively contains the call of LBP_NCKProcessIRT [FC3].
You will only need to distinguish between the triggering events in the program code of the
hardware interrupt OBs if you did not follow this recommendation and have assigned the same
hardware interrupt OBs to different events.

Remark
An auxiliary function can be defined as an auxiliary
function that is executed event-driven by setting the
corresponding parameter of the LBP_ConfigBP [FC1]:
● T function: IRAuxfuT
● H function: IRAuxfuH
● DL function: IRAuxfuE
M, S, F assignment for MCU link axes
Special type. No function but acknowledgment that AS‐
UP interrupt was executed.
Special type, is not evaluated.
