Channel Configuration, Data, and Status
This chapter examines the channel configuration word and the
channel status word bit by bit and explains how the module uses
configuration data and generates status during operation. It gives you
information about how to:
•
configure a channel
•
scale the channel data
•
check a channel’s status
Channel Configuration The channel configuration word is a part of the 1746-NI16 module’s
output image as shown below. The module output image uses 8
words when the module is in Class 1 mode and 32 words when the
module is in Class 3 mode. A description of the output image is
shown below.
