Programming and Parameters
558
Trend State
Value indicates the state of the Data Trend function.
• Value 0 - Wait Enable indicates the trend function is ready and waiting to begin data collection. Setting bit
0 “Enbl Collect” of
[Trend Control] will cause data collection to begin. In this state,
[TrendBuffPointer] and the Trend Output Parameters are active.
• Value 1 - First Scan indicates the Trend function is executing the first pass through the trend sample buffer.
This takes 512 ms. (0.5 ms x 1024 samples). When it enters this state, the Trend function clears bit 1
“Triggered” and 2 “Complete” bits of
[Trend Status]. While in this state, the Trend function
refreshes the data. Also while in this state, the function forces the Trend Output parameters to zero. When
done, it enters the Pre-trigger state.
• Value 2 - Pre-trigger indicates the Trend function is sampling the trend inputs and storing them in
memory, at a rate determined by
[Trend Rate]. Sampling continues until either the trend trigger
event occurs or bit 0 “Enbl Collect” of
[Trend Control] is cleared. While in this state, the Trend
function forces the Trend Output parameters to zero. If the trigger event occurs, the function sets bit 1
“Triggered” of
[Trend Status] and enters the Post-trigger state. If bit 0 “Enbl Collect” of Parameter
556 [Trend Control] is cleared, the function sets bit 2 “Complete” of Par 557 [Trend Status] and returns to
the Wait Enable state.
• Value 3 - Post-trigger indicates the Trend function is continuing to sample and save the trend inputs until
the buffer is full. While in this state, the function forces the Trend Output parameters to zero value. When
the buffer is full, the function sets bit 2 “Complete” of
[Trend Status] and enters the Wait Disable
state.
• Value 4 - Wait Disable indicates the Trend function is complete and waiting for bit 0 “Enbl Collect” of
[Trend Control] to be cleared. When this is done, the trend function returns to the Wait Enable state.
While in the Wait Disable state,
[TrendBuffPointer] and the Trend Output Parameters are active.

Trend TrigA DInt
Provides the integer input for the A trigger function. This integer is converted to a real number and summed
with
[Trend TrigA Real]. The result is compared with the Trigger B sum. If the A sum exceeds the B sum,
then a trend trigger will occur.

TrendBuffPointer
Selects the trend buffer element to be displayed in the Trend Output Parameters when the trend function is
inactive (not collecting data samples). A zero value points to the element that corresponds to the trigger event.
Negative values point to pre-trigger data. Positive values point to post-trigger data. When the Auto Output
function is running, this parameter will automatically sequence through it's full range, at a rate set by
[Trend Rate].
