In principle, the CQM1-ARM21 requires no special preparation in the CQM1
PLC system. However, to allow an AS-Interface configuration larger than 23
slaves, the Unit will need to occupy 8 IR words as input area, plus 8 IR words
as output area. With the 16 binary inputs already available in each CQM1
CPU, this would exceed the CPU's maximum of 16 I/O words (256 I/O points).
The full extent of the ARM21's I/O capacity is currently only supported by the
following CPU models:
CQM1-CPU41-EV1-NL
CQM1-CPU42-EV1-NL
CQM1-CPU43-EV1-CE
CQM1-CPU44-EV1-NL
CQM1-CPU45-EV1-NL
Produced after 01-04-1999 at OMRON Manufacturing of the Netherlands.
Lot No. 01 4 9 N
With the above models, support for the CQM1-ARM21's I/O range can be
activated by setting the following code in the CPU's PC Setup area:
DM6604 =
This code will allow the CQM1-ARM21 to access 2 additional IR words, above
the CPU's normal limitation of 16. This means that apart from the built-in
inputs of the CPU and a full-configuration AS-Interface master unit, one
additional I/O unit can be mounted.
