Appendix B Module Tag Definitions
Test Output Tags
Safety Output Tags
Tabl e 34 describes the 5094-IB16S module safety output tags.
Table 33 - 5094-IB16S Module Test Output Tags
Name Data Type Definition Valid Values
Testxx.Readback BOOL Indicates that a 24V DC power source is present at the
test output.
• 0 = 24V DC power is not present
• 1 = 24V DC power is present
Testxx.Fault BOOL • Indicates that channel data is inaccurate and
cannot
be trusted for use in the application.
For more information, see Module Data Quality
Reporting on page 47.
• The channel is set to Not Used.
• 0 = Good data
• 1 = Bad data (faulted) or set to Not Used
– 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, you must complete
the steps described in Safety Input Fault Reset
on
page 76 to reset this tag to 0.
– If the tag is 1 because the channel is set to Not
Used, no action is required.
Testxx.Uncertain BOOL Indicates that the channel 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
This tag is set to 1 when the module has reached a
critical operating temperature or is higher the
acceptable operating temperature.
IMPORTANT: Once the condition that causes the tag
to change to 1 is removed, the tag automatically
resets to 0.
Testxx.ShortCircuit BOOL Indicates an output short circuit • 0 = No short circuit
•1 = Short circuit
Testxx.FieldPowerOff BOOL Indicates that a field power loss condition exists on the
channel.
• 0 = No field power off condition
• 1 = Field power off condition
Testxx.Status BOOL Indicates the channel status. • 0 = Fault
•1 = Good
Table 34 - 5094-IB16S Module Safety Output Tags
Name Data Type Definition Valid Values
Pt00.ResetFault BOOL When ‘Latch Fault until reset via output tag’ mode is Enabled, the IO
channel will hold safety input fault indications until it checks that the
fault is removed. If the fault is removed, it will clear
only the fault
status upon detecting that the ResetFault bit in its channel sees a rising
edge.
Rising edge: the fault status is released if
the fault has been removed.
