Appendix B Module Tag Definitions
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.Chatter BOOL Indicates if the input is chattering per the ChatterTime and
ChatterCount settings.
• 0 = Normal
•1 = Input is chattering
Ptxx.TimestampOverflowOffOn BOOL Indicates an Off to On time stamp was lost in a discrete
product. If TimestampLatchEn is set then a new time
stamp was not recorded because one is already latched. If
TimestampLatchEn is clear a timestamp was overwritten.
0 or 1
Ptxx.TimestampOverflowOnOff BOOL Indicates an On to Off time stamp was lost in a discrete
product. If TimestampLatchEn is set then a new time
stamp was not recorded because one is already latched. If
TimestampLatchEn is clear a timestamp was overwritten.
0 or 1
Ptxx.CIPSyncValid BOOL Indicates whether the module is synced with a 1588
master.
• 0 = CIP Sync is not available
•1 = CIP Sync is available
Ptxx.CIPSyncTimeout BOOL Indicates that the module was once synced with a 1588
master, but is not now due to a timeout.
• 0 = A valid time master has not timed out.
• 1 = A valid time master was detected on the
backplane, but the time master has timed out.
The module is using its local clock and can be
drifting away from the last known time
master.
Ptxx.TimestampOffOnNumber INT An Off to On timestamp identifier for the currently
produced timestamp.
All values.
Ptxx.TimestampOnOffNumber INT An On to Off timestamp identifier for the currently
produced timestamp.
All values.
Ptxx.TimestampOffOn LINT 64 bit Timestamp corresponding to when a change of
state Off to On was recorded at the input.
All values.
Ptxx.TimestampOnOff LINT 64 bit Timestamp corresponding to when a change of
state On to Off was recorded at the input.
All values.
