Description

Real-time DAQ

The ADwin-Gold is a powerful Real-Time data acquisition system in a very compact and robust design. It includes many functions in a small package at a reasonable price. The ADwin-Gold is housed in a rugged, metal enclosure that includes a fast, local Real-Time CPU and memory, analog and digital inputs and outputs; as well as a USB or Ethernet interface for the communication with a PC. The local CPU enables input and output response times of 1 μs or less.

Analog Inputs

The analog inputs are connected via two 8-channel MUX and two PGA to 2×16-bit and 2×14-bit ADCs. Signal acquisition is controlled by the ADwin’s CPU, and possible to acquire two channels simultaneously without any phase-shift, critical for correlated signals. The ADwin-Gold has 2- or 8-analog outputs with an output range is ±10V.

Digital Inputs

The ADwin-Gold provides 32 programmable digital input and output channels at 5V-TTL/CMOS level, plus an Event input. The channels can be software selected in blocks of 8 as inputs or outputs. Optional configurations allow additional features such as counters, quadrature encoder interfaces, RS-232/485, automotive CANbus and SSI interfaces.

Software

ADwin operation with the PC

 

Multiple PCs can communicate with one ADwin system concurrently. This may be useful during the program implementation and setup. On the other hand, one PC can also access multiple ADwin systems e.g. in a network for a centralized monitoring of various applications.

While working with ADwin, the first step is always to download the real-time operating system to the ADwin system via the Ethernet or USB interface. Then, the ADbasic real-time processes can be loaded and started or stopped as required. Single values or whole data sets (arrays), e.g. measured or set-point values can be exchanged bi-directionally. The deterministic (exact and predictable in time) execution of the real-time processes is not affected by the communcation between ADwin and the PC.

Real-time development with ADbasic and ADtools

With ADbasic, you define the processing sequences that are executed on the ADwin hardware. ADbasic optimizes and compiles the program code on a mouse-click. After being loaded on the ADwin system by ADbasic or a graphical PC user interface, the real-time processes execute independently. ADbasic contains the functions to access all inputs and outputs as well as functions for floating-point operations, process control and communication with the PC. A library is provided which contains standard functions e.g. for filtering, various examples for counter use, closed-loop controllers, function generators etc. which leads to a faster program implementation.

With the easily configurable ADtools you are able to display your real-time data graphically or numerically, to visualize process sequencing or to set input values via potentiometers, sliders or push buttons. Additionally, ADtools always provide you with the current status of your ADwin system resources.
