5.12 TREND MODULES
There are eight configurable Trend Modules that can be configured separately. Each Trend Module provides storage of the last 80 sam-
ples of the specified input (the last 40 samples are displayed on the point trend line). The first four Trend Modules are attached to the
CON Modules if the Trend Rate datapoint in the CON Module is non-zero. If the trend is attached to a CON Module, then height, rate,
mode, span, zero, and designator parameters are overwritten with values from the CON Module.

Trend
Rate This parameter defines the recording rate in seconds
of the selected datapoint. Valid inputs are 1, 2, 3, 4, 5,
6, 10, 12, 15, 20, 30, and 60 seconds. A value of 0
turns off the trending. TRR

Span Samples outside this range are recorded at the limits.
When controlled by the CON module, values for these
datapoints come from the Controller Span and
Controller Lower Range. TRS

Desig-
nator This parameter designates the datapoint to be
recorded. It can contain any L, B, C, or H datapoint
specifier. When controlled by the CON module, this
parameter is set to the PV (specified datapoint) of the
associated CON module. TRP
