Channel Configuration, Data, and Status
This chapter examines channel configuration and status words, and explains
how you use them. It gives you information about how to:
configure a channel
check a channel's status
Channel configuration words appear in the SLC controller's output image
table as shown below. Words 0-3 correspond to module channels 0-3.
Words 4-7 are not used.
After module installation, you must configure each channel to establish the
way the channel operates (e.g., thermocouple type, temperature units, etc.).
You configure the channel by setting bits in the configuration word using
your programmer. We present bit descriptions next. (For information on
addressing. using your software, and programming, refer to chapters 4, 5
and 7, respectively.)

The configuration word default settings are all zero. Next, we describe
how you set configuration bits of a channel configuration word to set up
the following channel parameters:
type of thermocouple or mV input
data format such as engineering units, counts, or scaled for PID
how the channel should respond to a detected open input circuit
temperature units in
Allen-Bradley
whether the channel is enabled or disabled
