gram
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.
The function block has its own 32-marker-bit marker range for processing the inter-
rupt program.
Available functions within an interrupt program
