Control and status area

CS1-series

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+4.
The first two words are control words and are sent to the Unit. The next three
words are status words and are read from the Unit.
The mapping of the slave status words that are read from the Unit is defined
by the Unit settings (see section 5-1-2).
Note During a configuration download or when a fatal error occurs in the unit, the
control words IR n and IR n+1 will not be processed.
For details on the area allocation in CS1-series PLC's, see Appendix C.
