64 Configuration Parameters
Relay Number Sets the relay that triggers the trend to be collected. None means that the trend can only be
triggered manually or by a trigger
event (for example, XM-440).
Relay Number 1 is the on-board relay.
Numbers 2 through 5 are either relays
on the Expansion Relay module when
it’s connected to the module or virtual
relays.
Note: The relay must be enabled.
Refer to Relay Parameters on page 58.
Record Interval The amount of time between consecutive trend
records.
Note: If you enter a Record Interval, the Trend Span
is automatically updated.
1 to 3600 seconds
Trend Span The total amount of time that can be covered by the
trend data (Number of Records x Record
Interval).
Note: If you edit the Trend Span, the Record
Interval is automatically updated.
Seconds
Post Trigger The percentage of records to be collected once the
trigger occurs. For example, if you set Post Trigger to
20%, then 80% of the records in the trend are before
the trigger occurs, and 20% of the records in the
trend are after the trigger occurs.
This allows you to evaluate what happened after the
trigger occurred.
0 to 100 Percent
Status Shows the status of the trend data. Possible status values:
•
Not collected - No trend data is
currently collected.
•
Collecting - A trigger has occurred
and data (including post-trigger
data) is being collected.
•
Collected - A trend has been saved
to the buffer and is available to view
and upload.
View Trend Data Displays a plot of the collected trend data.
Reset Trigger Resets the trigger if Latch enabled is selected. This
allows the module to overwrite the previous trend
data when the next trigger occurs.
Manual Trigger Triggers the module to collect the trend data without
relay activation.
