Control and Status area
After initialisation of the Unit (RUN LED is ON), the control and status words
are exchanged between the PLC and the Unit during each I/O refresh. The
mapping of the control words and unit status words depends on the Machine
number set by the rotary switch at the front of the Unit.
The first word in the IR area allocated to the Unit will be indicated by IR n,
the last word by IR n+7. The following table gives an overview of the
meaning of these words.
