Nomenclature and Unit Settings Section 2-1
Unit No. Setting Switch The unit number setting switch (MACHINE No.) is the switch that sets the MC
Unit’s unit number as a Special I/O Unit.
The unit number setting determines which words in the CPU Unit’s Special I/O
Unit area are allocated to the MC Unit. The CS1W-MC221 occupies 30 words,
and the CS1W-MC421 occupies 50, so the unit numbers that can be set are
as follows:
CS1W-MC221: 0 to 93
CS1W-MC421: 0 to 91
n = 2000 + 10 x unit number
If anything other than the above is set, an error will be generated when the
power is turned ON.
As long as it does not overlap with the unit number of another Special I/O Unit
mounted at the same PLC, any settings can be made within these ranges.
