Output Channel Enable (configuration bits 0 and 8)

Use this bit to enable or disable a channel. To minimize update times, disable any
unused channels.
When you set the channel enable bit to one, the module reads the configuration
word. Before accepting any new data as valid, verify that the status word
(described in the last subsection of this chapter) reflects the changes you made.
While the channel enable bit is set to zero, the channel data word and status word
are also set to zero. When you reset the channel enable bit to one, the channel
data word remains set to zero until your module updates the channel status word.
Output Range (configuration bits 1–3 and 9–11)
Use this bit field to configure the channel for the type of output device you have
connected to the module.
Data Format (configuration bits 4–6 and 12–14)
Use this bit field to select one of the following formats:
• Engineering units (mV or nA).
• Scaled for PID (works with the SLC PID instruction).
• Proportional counts (two's complement binary).
• 1746-NO4 compatible format (the format used by the 1746-NO4).
• User-defined scale.
