Description
Fault
DINT
Binary
Fault - Used for Input Data Validation0 = Valid Data1 = Invalid Data - if the connection to the module has been lost, or if the module has a severe hardware fault, the lower 8 members are set to 1.

Ch1UnderrangeAlarm
Ch2UnderrangeAlarm
Ch3UnderrangeAlarm
Ch4UnderrangeAlarm
Ch5UnderrangeAlarm
Ch6UnderrangeAlarm
Ch7UnderrangeAlarm
Ch0OverrangeAlarm
These bits are set if 1) the input signal is above the input channel’s maximum range or 2) an open detector is detected.

Description
Config1
SINT
Binary
ModuleDataType0
These bits used in combination as follows:
00 = Degrees C (default)
01 = Degrees F
02 = Bipolar counts scaled between -32768 and 32767
03 = Unipolar counts scaled between 0 and 65535
ModuleDataType1
FixFilterEnable
BIT
Measures voltage drop across a precision resistor in the module to compare with the unknown input. This improves module temperature drift characteristics, but reduces module throughput.
NotchFrequency3
These bits are used in combination as follows:
0 0 0 10 Hz (default)
0 0 1 25 Hz
0 1 0 50 Hz
0 1 1 60 Hz
1 0 0 100 Hz
1 0 1 250 Hz
1 1 0 500 Hz
1 1 1 1000 Hz
NotchFrequency4
BIT
NotchFrequency5
BIT
CalibrationConfig
BIT
This bit is set during gain calibration, reset during offset calibration
OutOfRangeLEDEnable
BIT
This bit must be set to 1 to prepare for a calibration cycle; then reset to 0 to initiate calibration
