Fault and Status Reporting
The analog input module sends fault and status data with channel data to the
owner-controller and listening controllers. The data is returned via module tags that
you can monitor in your Studio 5000 Logix Designer application.
With some exceptions, the analog input module provides the fault and data status in a
channel-centric format. The tag names in the following table that include Chxx represent
channel-centric data. The xx represents channel number.
Data Type | Tag Name | Description |
|---|---|---|
Fault | ConnectionFaulted | 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. |
Chxx.Fault | 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.
| |
CJChxx.Fault | 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.
| |
Status | RunMode | Channel’s operating state. |
DiagnosticActive | Indicates if any diagnostics are active or if the prognostics
threshold is reached. | |
DiagnosticSequenceCount | Increments for each time a distinct diagnostic condition is
detected, and when a distinct diagnostic condition transitions from
detected to not detected. | |
Chxx.Uncertain | 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.
| |
CJChxx.Uncertain | The cold junction data can be inaccurate but it is not known to
what degree of inaccuracy.
IMPORTANT:
Once the condition
that causes the tag to change to 1 is removed, the tag
automatically resets to 0.
