Figure 199: Input and output states being passed between the main program and interrupt program
If an output is defined as a physical output on base device in the parameters for the
interrupt program, the output will be assigned an identifier of QP01 – QP04 and will act
directly on device output Q1 – Q4.
Zur Verarbeitung des Interrupt-Programmes hat der Funktionsbaustein einen eigenen
Merkerbereich von 32 Merker-Bits.
