I/O Word Allocation
Allocation for Group-2
High-density I/O Units
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
Group-2 High-density I/O Units are allocated words between IR 030 and IR 049
according to I/O number settings made on them and do not use the words allo-
cated to the slots in which they are mounted. For 32-point Units, each Unit is allo-
cated two words; for 64-point Units, each Unit is allocated four words. The words
allocated for each I/O number are in the following tables. Any words or part of
words not used for I/O can be used as work words or bits in programming.
32-point Units
I/O number
0 IR 30 to IR 31
1 IR 32 to IR 33
2 IR 34 to IR 35
3 IR 36 to IR 37
4 IR 38 to IR 39
5 IR 40 to IR 41
6 IR 42 to IR 43
7 IR 44 to IR 45
8 IR 46 to IR 47
9 IR 48 to IR 49
When setting I/O numbers on the High-density I/O Units, be sure that the set-
tings will not cause the same words to be allocated to more than one Unit. For
example, if I/O number 0 is allocated to a 64-point Unit, I/O number 1 cannot be
used for any Unit in the system.
Group-2 High-density I/O Units are not considered Special I/O Units and do not
affect the limit to the number of Special I/O Units allowed in the System, regard-
less of the number used.
The words allocated to Group-2 High-density I/O Units correspond to the con-
nectors on the Units as shown in the following table.

Note Group-2 High-density I/O Units cannot be mounted to Slave Racks and cannot
be used with the C200H-CPU01-E, C200H-CPU03-E, and C200H-CPU11-E.
