Configuration Parameters 55
trend records, the interval between trend records, and which relay triggers
(activates) the collection of the trend data.

Triggered Trend Parameters
Parameter Name Description Values/Comments
Enable Triggered Trend
Measurements Enables/disables the triggered trend measurements.
Select to configure the triggered trend
measurements. Check to enable.
Clear to disable.
Select Measurements Sets the measurements to be collected and stored in
the module. More than one measurement can be
selected.
Number of Records The maximum number of measurement sets that can
be collected in the trend buffer. The measurement
sets make up the trend data. The Number of Records is
automatically calculated based upon
the number of Trended
Measurements selected.
Latch Enable Determines whether the trigger trend is latched or
unlatched.
Latched means that subsequent triggers are ignored
after the initial trigger. This prevents the trend data
from being overwritten with new data until the
trigger is manually reset (click Reset Trigger button).
Unlatched means that the trend data is overwritten
with new data every time a trigger occurs.
Check means latched
Clear means unlatched
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 Numbers 1 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 49.
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
