Appendix B Module Tag Definitions
Input Tags
Table 37 describes the 5069-OF4, 5069-OF8 module input tags.
Table 37 - 5069-OF4, 5069-OF8 Modules - 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. -128…127
The value of 0 is skipped except
during module power-up.
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
– No Load 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.NoLoad BOOL The signal wire is disconnected from the channel or the RTB is removed from
the module.
This condition is detected only when the channel is used in current mode.
• 0 = No Load condition does not
exist
• 1 = No Load condition exists.
That is, a signal wire is
disconnected from the channel
or the RTB is removed from the
module.
