Module Tag Definitions Appendix B
Input Tags
Table 31 describes the 5069-IY4 module input tags.
Table 34 - 5069-IY4 Module - Input Tags
Name Size Definition Valid Values
RunMode BOOL Channel’s operating state • 0 = Idle
• 1 = Run
ConnectionFaulted BOOL Indicates if a connection is running.
The module sets this tag to 0 when connected. If the module is not
connected, it changes the tag to 1.
• 0 = Connection running
• 1 = Connection not running
DiagnosticActive BOOL Indicates if any diagnostics are active or if the prognostics threshold is
reached.
• 0 = No diagnostics active
• 1 = One or more diagnostics are
active or the prognostics
threshold is reached
DiagnosticSequenceCount SINT Increments for each time a distinct diagnostic condition is detected, and
when a distinct diagnostic condition transitions from detected to not
detected.
Set to zero by product reset or power cycle. Wraps from 255 (-1) to 1
skipping zero.
-127…128
The value of 0 is skipped except
during module power-up.
CJChxx.Fault BOOL Indicates that the cold junction 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.
CJChxx.Uncertain BOOL Indicates that the cold junction 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.
CJChxx.OpenWire BOOL The cold junction wire is disconnected from the channel or the RTB is
removed from the module.
If this condition exists, confirm that you are using one of the following RTBs:
• 5069-RTB14CJC-SPRING
• 5069-RTB14CJC-SCREW
• 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.
