Internal combi I/Os %IX0.0-%IX0.3 and
%QX0.0-%QX0.3
Software
The basic unit hosts a set of some I/Os which can be
assigned both normal and special functions.
� Inputs "read" the signals of switches, push-buttons,
initiators, etc. The generate interrupts and run the
input IRQ modules. The signal state is entered into
the process image.
Run function FLUSH_INPUTS to directly get the
signal states of internal inputs and of the inputs of the
basic module.
� Outputs deliver control signals to relays, contactors,
solenoids, etc. in order to turn them on or off. The
CPU enters the signals into the process image
depending on user program instructions. The output
data in the process image are sent to the outputs
between every two PLC cycles. Run function
FLUSH_OUTPUTS to directly get the signal states of
internal outputs and of the outputs of the basic
module.
If set up accordingly, the internal outputs can also be
used as clock pulse outputs for actuating stepper
motors compliant to a frequency table stored in the
PLC memory. The PLC program selects the correct
values from the table, maintaining a pulse-to-pause
ratio of 1:1 at all times. Whereas outputs do0 and do1
as well as do2 and do3 are actuated by the same
clock pulse, they can still be enabled and disabled
separately.
