Appendix B Module Tag Definitions
CJChxx.FieldPower BOOL Field power is present at the cold junction. • 0 = Field Power is present
• 1 = Field Power is not present
CJChxx.Underrange BOOL The cold junction at the channel is below the minimum of its operating
range.
• 0 = Channel data is not beneath
the absolute minimum
• 1 = Channel data is beneath the
absolute minimum
CJChxx.Overrange BOOL The cold junction at the channel is above the maximum of its operating
range.
• 0 = Channel data is not above
the absolute minimum
• 1 = Channel data is above the
absolute minimum
CJChxx.Temperature REAL Current temperature of the cold junction in degrees C.
This tag must use Celsius.
Any
Chxx.Fault BOOL Indicates that channel data is inaccurate and cannot be trusted for use in
the application.
If the tag is set to 1, you must troubleshoot the module to correct the cause
of the inaccuracy.
IMPORTANT: Once the condition that causes the tag to change to 1 is
removed, the tag automatically resets to 0.
• 0 = Good
• 1 = Bad, causing fault
The typical causes of uncertain
data are the following:
– Channel is disabled
– Open Wire condition
– Underrange/Overrange
condition
– Short Circuit condition
We recommend that you first
troubleshoot the module to see if
the typical causes exist.
Chxx.Uncertain BOOL Indicates that the channel data can be inaccurate but the degree of
inaccuracy is not known.
If the tag is set to 1, you must troubleshoot the module to correct the cause
of the inaccuracy.
IMPORTANT: Once the condition that causes the tag to change to 1 is
removed, the tag automatically resets to 0.
• 0 = Good data
• 1 = Uncertain data
The typical causes of uncertain
data are the following:
– Data signal slightly outside
the channel operating range
– The channel is slightly over
temperature.
– Invalid sensor offset value
– Calibration fault on the
channel
– Calibration is in process on
the channel
We recommend that you first
troubleshoot the module to see if
the typical causes exist.
Chxx.OpenWire BOOL The signal wire is disconnected from the channel or the RTB is removed from
the module.
• 0 = Open Wire condition does
not exist
• 1 = Open Wire condition exists.
That is, a signal wire is
disconnected from the channel
or the RTB is removed from the
module.
Chxx.OverTemperature BOOL Module is higher temperature than its operating limits.
• If this tag is set to 1 but a fault does not exist on the channel, this tag is
only an indication of operating conditions but the channel is functioning.
• If this tag is set to 1 and a fault exists on the channel, the channel is not
functioning.
• 0 = Module temperature is not
over the operating limits
• 1 = Module temperature is over
the operating limits
