D-10 Using Module Tags

I.CSTTimestamp[2] Per event 64-bit CST timestamp in CST format for the event.

This value is cleared after the data has been acknowledged via the O.EventAck tag. For

more information on clearing timestamp data, see page 7-17.

I.UCTTimestamp[2] Per event 64-bit UCT timestamp in Universal Coordinated Time format for the event. UCT is

expressed as microseconds elapsed since 1 January 1972. Typically, UCT format is only

used in applications that also use the 1756HP-GPS module. For more information on the

1756HP-GPS module, see Appendix B.

This value is cleared after the data has been acknowledged via the O.EventAck tag. For

more information on clearing timestamp data, see page 7-17.

I.EventPoint Per event Input that recorded the event. Values are 0 - 15, where 0 = Input 0, 1 = Input 1, etc.

I.EventData Per event Indicates if input transitioned OFF or ON.

0 = input transitioned OFF

1 = input transitioned ON

I.ReturningUCTTime Modulewide Indicates if timestamps are in UCT format rather than CST. Typically, UCT format is only

used in applications that also use the 1756HP-GPS module. For more information on the

1756HP-GPS module, see Appendix B.

0 = CST format

1 = UCT format

For more information on UCT format, see Appendix B.

I.EventsQueuedCount Modulewide Number of events currently stored in the module’s buffer that have not been read.

(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.
