Trend
Mode This parameter specifies the sampling method used to
record the selected datapoint. The time between
successive samples for an individual trend is one
second regardless of the Trend Rate (TRR - B355,
etc.) value. The recorded value is a representation of
all the samples within the specified recorded rate time
interval. The available representations are as follows:
0 - INST.
1 - AVG.
2 - MAX.
3 - MIN.
0 = Instantaneous value. (If TRR = 5, then samples at
every 5th second are recorded in the trend.)
1 = Average value. (If TRR = 5, then 5 samples are
accumulated for 5 seconds and averaged. The
average value is recorded in the trend.)
2 = Maximum value. (If TRR = 5, then each sample is
tested to be
greater than every second for 5 seconds
and the result will be the largest value, which is
recorded in the trend.)
3 = Minimum value. (If TRR = 5, then each sample is
tested to be
less than every second for 5 seconds and
the result will be the lowest value, which is recorded in
the trend.)

Trend
Height This parameter specifies the displayed height assigned
to a full scale sampled value, which determines
resolution and size of the trend display. When
controlled by a CON module, this value is fixed at
50.
TRH

B357 B360 B363 B366 B369 B372 B375 B378 47
Trend
Zero These two parameters set the upper and lower trend
display values in engineering units. The lowest value
is displayed as
0 and the highest value corresponds to
the height of the trend display.
