Measurement and Automation: Distributed I/O0 pages

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.
