Output Tags
Tab le 64 describes the 5094-OW4IS modules output tags.
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.
• Indicates OverTemperature and CriticalTemperature
situation in 5094-OW4IS module.
• Indicates Shock & Vibration reaching operation limits.
• 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.FieldPowerOff BOOL Indicates that a field power loss condition exists on the
channel.
• 0 = No field power off condition
• 1 = Field power off condition
Ptxx.Status BOOL Indicates the status of the channel. • 0 = Bad, causing a fault
• 1 = Good

Ptxx.Data BOOL Indicates the current digital output value. • 0 = Off
•1 = On
Ptxx.ResetFault BOOL When ‘Latch Fault until reset via output tag’ mode is
Enabled, the I/O channel will hold safety output 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.
