Module Tags Appendix B
I.EventOverflow SINT Per point Set for an input when the module either:
·
Does not timestamp a transition on the input – The module has
Timestamp Latch enabled and a similar transition has already been
timestamped on this input but has not been cleared via the O.EventAck
and O.NewDataAck output tags (
see page 76 ).
or
·
Overwrites previously-recorded timestamp data for the input – The
module has Timestamp Latch disabled and multiple transitions occur on
the input. In this case, timestamp data from new transitions are
recorded before previously-recorded transitions were cleared from the
input via the O.EventAck and O.NewDataAck output tags (see
page 76 ).
This value is cleared if the module is reset.
I.LocalClockOffset DINT[2] Modulewide The offset from the local clock to the system time. This value is useful for detecting
steps in time.
This value updates when a PTP update is received.
I.OffsetTimeStamp DINT[2] Modulewide The time when the PTP message was received to cause the Local Clock Offset to
update.
This value is initially zero. The first timestamp occurs when the module synchronizes
with the Grandmaster clock.
I.GrandMasterClockID DINT[2] Modulewide The ID number of the Grandmaster clock that the module is synchronized to.
I.Timestamp[8].OffOn DINT[2] Per point Timestamp value with an input’s OFF to ON transition. This tag is a 8 x 1 32-bit array.
This value is cleared after the data has been acknowledged via the O.EventAck and
O.NewData tags. For more information on clearing timestamp data, see
page 76 .
I.Timestamp[8].OnOff[2] DINT[2] Per point Timestamp value with an input ON to OFF transition. This tag is a 8 x 1 32-bit array.
This value is cleared after the data has been acknowledged via the O.EventAck and
O.NewData tags. For more information on clearing timestamp data, see
page 76 .
I.EventNumber.x DINT Modulewide Running count of the timestamped transitions; this tag increments by one with each
new transition that the module timestamps and rolls over to 1, not 0.
This value is cleared if the module is reset.
I.SyncToMaster BOOL Modulewide Indicates if the module is synchronized with a master clock.
1 = Synchronized
0 = Not synchronized
(1) With the Per point tags, there is one bit per input. For example, bit 0 represents input 0, bit 7 represents input 7 and so on.
