Measurement and Automation: Distributed I/O - ADLINK TECHNOLOGY - #1

Text version of the page

7-1 www.adlinktech.com High Speed Link (HSL) is an innovative distributed I/O technology based on the RS-485 open standard (supporting full/half-duplex, multi-drop serial transmission and designed for automation applications. An HSL system is a real-time I/O control system based on master/slave network architecture. Every slave module occupies 1-2 indexes. The HSL master card scans all slave indexes by polling. Scanning every slave index is time deterministic (the fastest response time is 15.1 ìs). The network employs CRC-12 for error correction and standard CAT-5 cables for point-to-point connections between major components. ADLINK's HSL master board has up to two HSL network ports and can connect up to 126 slave indexes. The slave modules can also be placed near monitored or controlled I/O points, reducing wiring and minimizing potential noise and signal loss. As a result, HSL systems provide excellent solutions where a single board can control over 2,000 I/O points or over 60 axes for motion control despite IPC resource limitations. Deterministic scanning time also provides an easy and stable way to build up the entire system. Distributed Real-time I/O Control System High Speed Link Bus An HSL solution is the best choice for optimal high-speed and easily distributed I/O systems, such as precision machine tools, industrial equipment (including instrumentation and control systems), automation equipment, research facilities, building administration systems, and conveyor systems.
