Data Acquisition Process Descriptions
Use data acquisition processes to acquire sensor data from the physical specimen
during testing.
You must sequence this process in parallel with command processes. Meaningful
data cannot be acquired unless the command process is performing an action that
can be measured.
Data Acquisition Process Types
I CON P ROCESS N AME D ESCRIPTION
Peak/Valley Acquisition
Process Records the peak/valley data for each cycle execution.
Timed Acquisition Process Records data at user-specified time intervals.
Max/Min Acquisition Process Records data at the highest peak and lowest valley during the life
of the process.
Level Crossing Acquisition
Process Records data each time the selected signal changes by a specified
amount.
High Speed Timed
Acquisition Process Records bursts of data at a high rate.
Cyclic Acquisition Process Records timed, level crossing, interleaved timed and level
crossing, or peak/valley data from cyclic feedback.
Fatigue Process Accumulates cycles in a histogram, then calculates damage based
on the data on that histogram. The damage number is also sent to
the Fatigue Monitoring application.
Time History Input Process Acquires and digitizes multiple channels of analog test response
data in the RPC III file format.
Trend Process Calculates statistical values on time series data. The values are then
stored to disk. It is also sent to the Trend Monitoring application.
