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
Par 556 [Trend Control] will cause data
collection to begin. In this state, Par 569 [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
Par 557 [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
Par 559 [Trend Rate]. Sampling continues until
either the trend trigger event occurs or bit 0 “Enbl Collect” of Par 556 [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
Par 557 [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
Par 557 [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
Par 556 [Trend Control] to be cleared. When this is done, the trend function
returns to the Wait Enable state. While in the Wait Disable state, Par 569
[TrendBuffPointer] and the Trend Output Parameters are active.

560 Trend TrigA DInt
Provides the integer input for the A trigger function. This integer is converted to a real
number and summed with
Par 561 [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.

561 Trend TrigA Real
Provides the real input for the A trigger function. This real number is summed with Par 560
[Trend TrigA Int]. The result is compared with the Trigger B sum. If the A sum exceeds the B
sum, then a trend trigger will occur.

562 Trend TrigB DInt
Provides the integer input for the B trigger function. This integer is converted to a real

Par 563 [Trend TrigB Real]. The result is compared with the
Trigger A sum. If the A sum exceeds the B sum, then a trend trigger will occur.

564 Trend Trig Data
This is the logic input for the Trend Trigger Function. A trigger will occur on the rise of the

565 Trend Trig Bit
Specifies the bit in Par 564 [Trend Trig Data] that will cause a Trend Trigger to occur.
Positive numbers specify rising edges and negative numbers specify falling edges.

RW 16-bit
Integer
566 Trend PreSamples
Specifies the number pre-trigger samples in the trend buffer. Pre-trigger samples are the
samples that occur before the trigger and remain in the buffer. The remainder of the trend
buffer will contain post-trigger samples.

569 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
Par 559 [Trend Rate].
