The ADwin-X-A20 is a real-time data acquisition and control system that offers high performance and numerous interfaces in a compact, robust metal housing, suitable for installation in a control cabinet or as a portable device.
A high performance, 666 MHz dual-core XILINX ZYNQ™ processor, similar to the ADwin-Pro II, provides extensive real-time computing power for programs developed with ADbasic or from a Simulink model (ADsim). A GB Ethernet interface allows high-speed communication between the local processor and an external PC or workstation.
The ADwin-X-A20 can also be customized to serve as the basis for your OEM applications. By choosing the standard version customized with a range of additional options, the ADwin-X-A20 can be quickly integrated into low or large volume data acquisition and control projects.
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 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 communication 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 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.
