if there are too many events exceeding the regeneration buffer, then the number
of events regenerated is limited to the capacity of the buffer. This can impact
recording the events in last 20 seconds.
The regenerated events have a timestamp of the actual event and therefore, you can see
duplicate events after the event regeneration has occurred.

EVTOPT and DIMODE dependency
The following occurs to the EVPTOPT with regards to the DISOE.
If
Then
EVTOPT = None (Default Value)
The DIGITAL INPUT SEQUENCE OF
EVENTS IOM is Normal (DIGITAL
INPUT 24VDCV mode) or the Low
Latency mode.
Digital Input channels of DIGITAL INPUT
SEQUENCE OF EVENTS IOM operating
in Sequence of Events mode do not
report Sequence of Events events and
vice versa.
If you change the EVTOPT value to
Sequence of Events when the DIMODE
parameter has either Normal or Low
Latency.
The following error is reported:
"EVTOPT incompatible with module's
DIMODE"
