14 • HSLink IntroductionSlave Number: A complete HSLink system must be composed of onemaster and 1~63 slaves. In the following graph, a layout example of HSLinksystem is presented.Figure 1.12: HSLink system layout example-serial wiringEach circuit from master could equip at most 32 slaves. However, themaximum number of slaves is 63, not 64. This is because the slaveaddress is decided by a 6 -bit DIP-switch on I/O module’s termination board,and the value ‘0’ is reserved. All slave I/O modules at the same HSLink setmust be configured different slave addresses. These addresses aren’tnecessary to be continuous from 1. However, continuous addressing will bemore efficient. Actually, if some user set up a HSLink system with only 2slave modules addressed 1 & 63, the I/O refreshing rate is exactly the sameas a 63-slave, addressed from 1 to 63, HSLink system.Please refer to chapter 3 “HSLink-Slave I/O Module” for completeddescriptions regarding how to set addresses of slave I/O modules.1.4.4 WiringThe HSLink network follows RS422 electrical spec, but not exactly the same.ÿ Wiring:The wire cables of HSLink system are carefully chosen to satisfy botheasiness and standardization requirement without sacrificingcommunication quality. A 100BaseTX cable with RJ45 connectors isselected for HSLink system.16DO16SE16DI8R16DI 16DI16DI
