Add affordable Web browser technology to integrate Smart Devices with LonTalk and Ethernet using LNS Server. May 7, 2003 - San Ramon, California Broadwin Technology Inc. announces the release of the LNS communication driver for use with devices using LonWorks based communications from Echelon and other smart device manufacturers. WebAccess HMI & SCADA automation software communicates directly to an LNS server. The protocol underlying LonWorks networks and the signaling technology used by Echelons power line and free topology transceivers have been adopted as standards by the American National Standards Institute (ANSI). LonWorks (commonly called LON) is found in the Building Automation and Facilities Automation industries. LonWorks enabled processors have been shipped for use in homes, buildings, factories, trains, and other systems worldwide. Broadwin WebAccess is the first fully Web browser-based software package for industrial and building automation front-ends, Human Machine Interfaces (HMI) and Supervisory Control and Data Acquisition (SCADA). Using a standard Web-Browser, users can view and control automation equipment used in manufacturing facilities, industrial process plants and building automation systems. "Organizations with multiple locations find it a major challenge to integrate the various communications types used in Building Automation. A single user interface to devices using LON, BacNet, and other protocols is required to predict energy costs, ensure security, and increase operational efficiency," said Tom Carter, Broadwins WebAccess Product Manager. "As Facilities Engineers and Managers try to monitor dozens of locations, it becomes clear that WebAccess SCADA is paramount to success – one that meets the need for a scalable, open infrastructure capable of integrating all the networking pieces together through one single enterprise system. We are looking closely at Echelons LONtalk and LNS Server is another platform integrated into Broadwins WebAccess to help meet that need." Key Features of WebAccess HMI & SCADA include: Web browser for User access to LNS systems using full animation. Integrate mixed communications protocols (LonWorks, BACNet, Modbus, and more) into a single user interface. Built-in Alarming. Email Notification of Alarms. Integrated Video. Scheduler. Trending, Data Logging, and Scheduled Reports. Multi-Layer Security. Fully Scaleable Web application with Management Tools. Object Oriented Vector-based Graphics. Fastest Display and Communications performance. Robust, Redundant SCADA Nodes and Communication Ports.

Full Animation Client WebAccess uses Active-X technology to provide real-time data, trends and full-animation graphics. The WebAccess Client is available for desktop computers and laptops running Microsoft 32-bit operating system including Windows 98, ME, NT 4.0, 2000, XP Home and XP Professional. Thin Client The Web Access thin client interface is compatible with on all 32-bit Microsoft Operating systems including Microsoft Windows CE, 95, 98, ME, NT 4.0, 2000, XP Home and XP Professional. SCADA Node WebAccess SCADA node software communicates in real-time with automation equipment via Serial, Ethernet or proprietary communications. WebAccess communications drivers are the fastest available and provide communications with a wide range of Programmable Logic Controllers (PLCs), Single Loop Controllers, Direct Digital Control Systems (DDC), Distributed Control Systems (DCS) and IO (input / Output) systems. The WebAccess SCADA Node software is available for desktop computers and laptops running Microsoft 32-bit operating system including Windows NT 4.0 Workstation, NT 4.0 Server, 2000 Professional, 2000 Server, XP Professional and XP Embedded. Project Node The WebAccess Project Node is an ordinary Web Server using Microsoft IIS (Internet Information Server), a standard option in Windows 2000 Professional, 2000 Server, XP Professional and XP Embedded.
