Scensys Ltd announces, PowerDNA - which refers to Distributed, Networked Automation and control - a system that sets a new industry standard for hard realtime I/O using conventional Ethernet cabling. Developed by United Electronic Industries, the modular system is optimised for realtime control applications requiring both large numbers of analogue and digital I/O points in distributed locations as well as extremely fast response. Thanks to the patent-pending DaqBIOS protocol, a PowerDNA system consisting of a PCI/PXI-based controller and multiple distributed nodes with more than 800 mixed analogue and digital I/O points, can guarantee a response time in less than imsec. In addition, when control situations arise, the latest algorithms allow as many as 64 PID loops to be operated. Under PC control or using PXI/Compact PCI (as shown above), and communicating through conventional Ethernet cabling, the PowerDNA system can poll up to 800 mixed I/O points in less than I msec. Users can configure the remote I/O Cubes with a variety of analog and digital I/O options. At the highest level, PowerDNA consists of a Central Controller card that fits into a host PC or PXI/CompactPCl system. To each of its two Ethernet ports users can attach as many as 64 I/O Cubes. Each I/O Cube in turn consists of a metal enclosure typically 4" x 4" x 4" that contains a Communications layer, a CPU layer with an embedded realtime kernel, and positions for either three or six I/O layers. Customers select the desired functionality from a range of I/O layers, which are factory installed, configured and calibrated. When configuring an I/O Cube, users can select from several I/O Layers: * analog input (16 or 32 channels, 16-bit resolution, sampling rate to 160 kHz) * direct temperature-sensor inputs (25 channels, 24-bit resolution, sampling to 500 Hz) * analog output (8 channels, 12- or 16-bit resolution, update rate to 160 kHz samples/sec) * digital I/O (with 16 inputs, 16 outputs, or 48 mixed I/O) * serial communication (eight RS232/485 ports) Users program their applications in C using a straightforward API that provides access to all hardware functionality. After compiling an application on the host PC, engineers can download it to an I/O Cube in several ways: over the Ethernet, over a serial link or over a USB port. The application can run under host control or as a standalone task. "We have listened to the voice of the customer and have developed PowerDNA, which will easily meet the needs for distributed hard realtime I/O for the next decade, "comments Shaun Miller, president of UEI. "For several years engineers could purchase Ethernet-based I/O but with insufficient realtime response to address future system requirements. However, our extensive investment in developing the DaqBIOS protocol has solved this problem." __________________________________________________ For more details of this product... email our HelpDesk quoting Ref. shown below Ref: Scensys017 January 2003
