Data-Logging with Real-Time pre-processing of Data
ADwinreal-time systems are ideal for intelligent data acquisition and control applications. By utilizing the
programmability of the ADwin’slocal CPU, users can run real-time logging and/or control programs with
execution speeds in the kHz to MHz range.
The new ADlog data logging software for the ADwinsystems opens new fields for intelligent data-logging
applications when combined with the capabilities of the ADwinhardware and real-time software.
- Take advantage of intelligent data acquisition with real-time, on-line analysis along with complex triggering, performed at every sampling step
- Perform online mathematical calculations, including statistics such as RMS, min/max, mean, integral, derivative, correlation, digital filters, FFT, signal analysis, etc., in the ADwinsystem
- Execute sampling based on timer, angular encoder, internal or external trigger, etc.
- Run other functions in addition to data acquisition on the same system including open- and closed-loop control functions, and signal and waveform generation
ADlog Data Logging Software
- Visualize current data of the ADwinsystem on the PC
- Store results in selectable file formats on the PC or on a Server
- Ready to use measurement routines for all ADwinsystems
- Supports many different types of input modules including analog/digital inputs, counter, encoder inputs, CAN bus interface, serial interface, SPI, etc.
- Can be integrated into any ADwinapplication for data acquisition or control
ADlog enables new advanced functionality for data logging applications
Overview of ADlog
ADlog consists of two parts: a data collection routine that runs on the ADwinsystem; and a display
and storage application that runs on the PC. By default, the ADwinportion of ADlog is configured as Process
9 and it uses 2 arrays (Data_180 and Data_181) to transfer data and manage the transfer; however these
settings can be modified by the user. Over two dozen sample routines are provided for data collection from
different types and input configurations of the ADwinsystem.
The PC application reads the data from the ADwin, graphs it, and logs it to one or more files. Up to 8
graph windows can be displayed and data can be plotted vs. data index, or time. Facilities are provided to
scale the data and apply different mathematical functions, such as a low-pass filter, before the data is
plotted. The data can be saved as ASCII, binary, or DIAdem format. It can also be saved in a single file or
multiple time-stamped files. Recording can be started manually or triggered based on data from the ADwin. The software also allows for recording pre-trigger data and limiting the length of the recording interval.
