    I'm sorry. I just realized that your questions was about S4 controller. :oops:
    I only used those interrupts on IRC5 controllers and for that reason my answer might be invalid.

    Hi Torben59


    I would do that with interrupts. Interrupts monitor the state of (your) pre-defined inputs and they are not synchronized to a specific code position. As soon as the monitored digital input is in a certain state (for example HIGH), the program pointer jumps to a so called trap routine.


    So, what to do in the RAPID code?
    1. create (define) an interrupt identity intnum
    VAR intnum error;


    2. Connect this interrupt with your trap routine
    PROC main()
    CONNECT error WITH alarm_trap;


    3. Define input and its state you want to monitor
    ISignalDI di1, high, error;


    4. Write your trap routine -> behavior if the signal (error) occurs
    TRAP alarm_trap
    !do something
    ENDTRAP


    I got most of the information out of ABB's manuals: Technical reference manual - RAPID overview & Technical reference manual - RAPID Instructions, Functions and Data types.
