Ambient Temperatures
The analog input modules measure the temperatures of each
terminal block on up to 4 AITBs in tenths of a degree
Fahrenheit.
These give the cold junction compensation temperature in
degrees F for each half of the terminal block. Note that the
channel numbers associated with a given cold junction
reference depend on whether the card is single ended or
differential.

Modules Present
Eight registers are required to describe the features and
capabilities of each module. As many as 12 modules may be
inventoried on start-up, totalling 96 registers. After the
inventory routines run, the registers are updated with the
current configuration. Refer to Table 5.56 and Table 5.57 on
page 212. These settings are read-only.
