Per Point Mode of Operation

The Per Point mode of operation provides a single On and Off timestamp for
each input point on the module. The 1732E-IB8M8SOER module employs
employs CIP Sync Per Point.

Per Point operation begins with the selection of the appropriate Timestamp
Format in RSLogix 5000 software.

Choosing the Per Point Timestamp Format results in an input tag structure with
a single On and Off timestamp value per input point, as well as some additional
general-purpose CIP Sync status tags. It results in the creation of two additional
input tags to assist in timestamp corrections in a CIP Sync architecture:
I:LocalClockOffset and I:OffsetTimestamp.

Events Module User Manual, publication

.

The Latch checkbox latches CIP Sync timestamp so that recorded events are not
discarded until you acknowledge them. As a result, if latching is selected and new
events occur, they will be ignored until the existing event is acknowledged.
