Module Tag Definitions Appendix B
Output Tags
Tab le 54 describes the 5094-OB8 module output tags.
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
powerup.
Ptxx.Data/PtxxData BOOL Indicates the current digital input value. • 0 = Off
•1 = On
Ptxx.Fault/PtxxFault BOOL Indicates that point data is inaccurate and cannot be trusted
for use in the application.
For more information, see Module Data Quality Reporting
on
page 47.
• 0 = Good
• 1 = Bad, causing fault
The typical causes of uncertain data are the
following:
– Field Power Loss condition
– No Load condition
– Short Circuit condition
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.
Ptxx.Uncertain BOOL Indicates that the point data can be inaccurate but the
degree of inaccuracy is not known.
For more information, see Module Data Quality Reporting
on
page 47.
• 0 = Good data
• 1 = Uncertain data
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.
Ptxx.NoLoad BOOL Indicates that the signal wire has been disconnected from
one of its terminals or the RTB has been removed. Used with
Output points.
•0 = No fault
•1 = Fault
Ptxx.ShortCircuit BOOL Indicates an output short circuit or overcurrent. • 0 = No short circuit
• 1 = Short circuit or overcurrent
