read and written in the interrupt routine, triggered by the input edge. Reading and writing can be
stopped via the function inputs READ_INPUTS, WRITE_OUTPUTS and ANALOG_INPUTS.
So in the program block all time-critical events can be processed by linking inputs or global variables
and writing outputs. So functions can only be executed if actually called by an input signal.
NOTE
The program block should be skipped in the cycle (except for the initialisation call) so that it is not
cyclically called, too.
The input (CHANNEL) monitored for triggering the interrupt cannot be initialised and further processed
in the interrupt routine.
The inputs must be in the operating mode IN_FAST, otherwise the interrupts cannot be read.
NOTE
The uniqueness of the inputs and outputs in the cycle is affected by the interrupt routine. Therefore only
part of the inputs and outputs is serviced. If initialised in the interrupt program, the following inputs and
outputs will be read or written.
Inputs, digital:
%IX0.0...%IX0.7 (CRnn32)
%IX0.12...%IX0.15, %IX1.4...%IX1.8 (all other ClassicController, ExtendedController, SafetyController)
%IX0.0, %IX0.8 (SmartController)
IN08...IN11 (CabinetController)
IN0...IN3 (PCB controller)
Inputs, analogue:
%IX0.0...%IX0.7 (CRnn32)
All channels (selection bit-coded) (all other controller)
Outputs, digital:
%QX0.0...%QX0.7 (ClassicController, ExtendedController, SafetyController)
%QX0.0, %QX0.8 (SmartController)
OUT00...OUT03 (CabinetController)
OUT0...OUT7 (PCB controller)
Global variants, too, are no longer unique if they are accessed simultaneously in the cycle and by the
interrupt routine. This problem applies in particular to larger data types (e.g. DINT).
All other inputs and outputs are processed once in the cycle, as usual.
