  • Page 7 How to use This Manual This manual is written to help you to use the HSLink series products. It describes the versatile functions and the operation theorem of the HSLink. This manual is divided into 4 chapters: Chapter 1 “HSLink Introduction” gives an overview of the HSLink system regarding system features, applications, and specifications.

  • Page 9: Chapter 1 Hslink Introduction

    HSLink Introduction What Is HSLink System HSLink is an innovative distributed I/O technology which allows thousands of I/O points to be scanned in mini-second-level real time by using 1 to N mater-slave architecture. The HSLink master is a PCI-bus card plugged into CPU Unit of PCC, and by using commercial Ethernet cable with RJ45 connector user may easily settle the HSLink slaves as close as possible to sensor devices.

  • Page 10: Features Of Hslink System

    1.1.2 Features of HSLink System Ø High speed It takes just 30.1μs for a HSLink master to scan all the I/O points in a slave module. Take HSL-DI16DO16-DB-NN as an example, This slave I/O module supports 16DI and 16DO, and these 32 I/O points could be scanned (or updated) in 30.1μs.

  • Page 11: Application Of Hslink

    Ø Modular design of slave I/O All kinds of slave I/O module are mechanically of the same size and follow the identical connecting PIN assignment. To fit into various wiring situations to keep flexibility, the HSLink Terminal Base is introduced. HSLink TB acts as an carrier of salve I/O module with wiring function.

    HSLink Technical Information 1.4.1 HSLink Technology Brief HSLink is a 1 -master-n-slave command-response communication system. The one and only one master sends commands to slave I/O modules for setting output values and requesting input information. Every slave responses when receiving commands with slave number of its. The response is either to set output according received values or to reply requested input information to master.
