Exchanging Data with the CPU Unit
Section 4-1
Data Allocation in the User Settings Area
DM Area
The Unit’s various user settings are made in the Special I/O Unit words in the
DM Area. Settings such as the alarm settings and span/zero adjustment val-
ues can be changed while the CPU Unit is operating.
Note
The unit number switch setting on the front panel of the Unit determines which
words in the Special I/O Unit Area and DM Area words are allocated to each
Universal Input Unit.
