.ModuleFaults
Below are a collection of all module level fault bits. Bits are defined as
follows:
0 - 7 are unused
8 - CJOverrange
9 - CJUnderrange
10 - unused
11 - CalFault, set if IF8U_Input.ChannelStatus[x].CalFault bit is set
12 - unused
13 - unused
14 - InGroupFault
15 - AnalogGroupFault
Any bit set in the ChannelFaults word sets both the InGroupFault and
AnalogGroupFault bits.
.AnalogGroupFault
Indicates if a channel fault has occurred on any channel.
.InGroupFault
Indicates if a channel fault has occurred on any channel.
.CalFault
Status bit indicating if any channel has a bad calibration means that the last
attempt to auto calibrate the channel failed with an error and was aborted.
.CJ0Underrange
Status bit to indicate if the Cold junction sensor CJC0 reading is currently
beneath the lowest detectable temperature of 0.0 degrees Celsius or open
wire.
.CJ0Overrange
Status bit to indicate if the Cold junction sensor CJC0 reading is currently
above the highest detectable temperature of 90.0 degrees Celsius or short
circuit.
.CJ1Underrange
Status bit to indicate if the Cold junction sensor CJC1 reading is currently
beneath the lowest detectable temperature of 0.0 degrees Celsius or open
wire.
.CJ1Overrange
Status bit to indicate if the Cold junction sensor CJC1 reading is currently
above the highest detectable temperature of 90.0 degrees Celsius or short
circuit.
.CJCCalFault
Status bit to indicate if the Cold junction sensor CJC1 or CJC2 calibration
failed.
