Analog Input Data Format
Table 20 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 bits 8…10
in words 3, 9, 15, and 21 to make this selection.
Analog Input Type and Operating Range
Table 21 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.
