Description
Channel Temperature Data
The temperature count mapped from temperature Celsius degree
with one decimal. Please check the section,
Conversion – Data to Degree Celsius (°C) on page 23
, for the
mapping formula.
UKT (Unknown Type)
Bit set to report an unknown sensor type error in configuration.
UKR (Unknown Rate)
Bit set to report an unknown update rate error in configuration.
OR (Overrange)
Bit set to indicate overrange on channel input. The Channel
Temperature Data shows maximum temperature count for
individual type of sensor used and the value does not change
until overrange error is clear.
UR (Underrange)
Bit set to indicate the channel input underrange happens. The
Channel Temperature Data will show minimum temperature
count for individual type of sensor used and the value does not
change until underrange error is clear.
OC (Open Circuit)
Bit set to indicate open-circuit on the channel input sensor.
DI (Data Illegal)
The data in the channel data field is illegal and cannot be used
by user. This bit is set when temperature data is not ready for
use.
CC (Code Calibrated)
Bit set indicates temperature data is calibrated by the system
calibration coefficient.
SOR (System Overrange)
Bit set to indicate system overrange error with environment
temperature over 70 °C.
SUR (System Underrange)
Bit set to indicate system underrange error with environment
temperature under -20 °C.
COC (CJC open-circuit)
Bit set to indicate CJC sensor not connected for thermocouple
module, open circuit. This bit is for thermocouple module only.
CE (Calibration Error)
Bit set indicates that the module is not accurate. This bit is set to
0 by default and should remain as 0. Contact Technical Support
when the value is otherwise.
