1251 Trend Status
Bits indicate the status of the Data Trend function:
• Bit 1 [Triggered] indicates a Trend Trigger event has been detected. This bit will clear in response to the rise of Par 1250 [Trend Control], bit 0 [Enbl Collect].
• Bit 2 [Complete] indicates all the post trigger data samples have been gathered and the trend buffers are full. It will also be set if the Par 1250 [Trend Control], bit 0
[Enbl Collect] is cleared before the trigger occurs. The trend data outputs will be updated from the contents of the trend buffer data when this bit is set. Par 1250
[Trend Control], bit 0 [Enbl Collect] can be cleared after this bit is set without affecting the trend data buffer contents. This bit will clear in response to the rise of Par
1250 [Trend Control], bit 0 [Enbl Collect]. The trend outputs will be forced to zero while this bit is clear.
1252 Trend State
Value indicates the state of the Data Trend function.
• 0 “Wait Enable” - indicates the trend function is ready and waiting to begin data
collection. Setting bit 0 [Enbl Collect] of Par1250 [Trend Control] will cause data
collection to begin. In this state, Par 1283 [TrendBuffPointer] and the Trend Output
parameters are active.
• 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 bit 2 [Complete] of Par 1251 [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.
• 2 “Pre-trigger” - indicates the Trend function is sampling the trend inputs and storing
them in memory, at a rate determined by parameter 1253 [Trend Rate]. Sampling
continues until either the trend trigger event occurs or bit 0 [Enbl Collect] of Par 1250
[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 1251 [Trend Status] and enters the Post-trigger state. If bit 0 [Enbl Collect] of Par
1250 [Trend Control] is cleared, the function sets bit 2 [Complete] of Par 1251 [Trend
Status] and returns to the Wait Enable state.
• 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. When the buffer is full, the function sets bit 2 [Complete] of Par
1251 [Trend Status] and enters the Wait Disable state.
• 4 “Wait Disable” - indicates the Trend function is complete and waiting for bit 0 [Enbl
Collect] of Par 1250 [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 1283
[TrendBuffPointer] and the Trend Output Parameters are active.

1254 Trend TrigA Int
Provides the integer input for the A trigger function. This integer is converted to a real
number and summed with Par 1255 [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.

1260 Trend PreSamples
Specifies the number of 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.
