Using Module Tags D-5
I.ReturningUCTTime
Modulewide
Indicates if timestamps are in UCT format rather than CST.
0 = CST format
1 = UCT format
For more information on UCT format, see Appendix B.
I.EventNumber.x
Modulewide
Running count of the timestamped transitions; this tag increments by one with each
new transition that the module timestamps. In CST Per Point mode, this tag has lesser
importance than in FIFO mode.
This value is cleared if the module is reset.
I.Timestamp[16].OffOn[2]
Per point
Timestamp value (in CST or UCT format) with an input’s OFF to ON transition. This tag is
a 16 x 2 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 6-12.
I.Timestamp[16].OnOff[2]
Per point
Timestamp value (in CST or UCT format) with an input’s ON to OFF transition. This tag is
a 16 x 2 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 6-12.
