Publication 1746-UM007C-EN-P - July 2004
Channel Configuration, Data, and Status 5-15
Status Conditions Input Type Status (Bits 0-3)
The input type bit field indicates what type of input signal you have
configured for the channel. This field reflects the input type defined in
the channel configuration word.
Data Format Type Status (Bits 4 and 5)
The data format bit field indicates the data format you have defined
for the channel. This field reflects the data type selected in bits 4 and
5 of the channel configuration word.
Open Circuit Type Status (Bits 6 and 7)
The open-circuit bit field indicates how you have defined the
configuration word and, therefore, the response of the thermocouple
module to an open-circuit condition. This feature is active for all input
types, including CJC temperature input.
IMPORTANT
If the channel for which you are seeking status is
disabled (bit O:e.x/11 = 0), all bit fields are cleared.
The status word for any disabled channel is always
0000 0000 0000 0000 regardless of any previous
setting that may have been made to the configuration
word.
