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.
For allocation in CS1-series PLC's, see Appendix C.
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.
