5-8 Channel Configuration, Data, and Status
Input Image - Channel Data
Word
The module input image uses 8 data word values in Class 1 and 16
data word values in Class 3. The converted voltage or current input
data values reside in I:e.0 through I:e.7 (Class 1) or I:e.0 through I:e.15
(Class 3) of the module’s input image file. When an input channel is
disabled, its data word is reset to zero.
