Chxx.Fault
Size Definition
REAL The High High alarm trigger point. Causes the ChxxHHAlarm to trigger when
the input signal moves above the configured trigger point. In terms of
engineering units.
REAL The Rate alarm trigger point. Causes the ChxxRateAlarm to trigger when the
input signal changes at a rate faster than the configured rate alarm.
Configured in Engineering Units per second.
REAL Allows a process alarm to remain set, despite the alarm condition
disappearing, as long as the input data remains within the deadband of the
process alarm.
The deadband value is subtracted from the High and High High Alarm Limits
to calculate the deadband thresholds for these alarms. The deadband value
is added to the Low and Low Low Alarm Limits to calculate the deadband
thresholds for these alarms.
Table 31 describes the 5069-IF8 module input tags.
Size Definition
BOOL Channel's operating state
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.
BOOL Indicates if any diagnostics are active or if the prognostics threshold is
reached.
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.
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.

Module Tag Definitions Appendix B
Valid Values
100.0 = default
0 = Rate Alarm is not used
Any value greater than zero = Trigger point
Any non-negative value
0 = default
Valid Values
• 0 = Idle
• 1 = Run
• 0 = Connection running
• 1 = Connection not running
• 0 = No diagnostics active
• 1 = One or more diagnostics are
active or the prognostics
threshold is reached
-128...127
The value of 0 is skipped except
during module power-up.
• 0 = Good
• 1 = Bad, causing fault
The typical causes of uncertain
data are the following:
– Channel is disabled
– Open Wire (input modules)
or No Load (output
modules) condition
– Underrange/Overrange
condition
– Short Circuit condition
We recommend that you first
troubleshoot the module to see if
the typical causes exist.
