Analog Input Data Format
Tab le 21 lists the bit value combinations you can use to select the output data
format for analog data that is sent to the controller for a channel.
You use bi ts
8…10 in words 3, 9, 15, and 21 to make this selection.
Analog Input Type and Operating Range
Tab le 22 lists the bit value combinations you can use to select the input type
and operating range for a channel.
You use bits 0…5 in words 3, 9, 15, 21, 29, and 37
to make the selections.
