This topology consists of fieldbus devices connected to a multidrop bus segment through a length of cable called a spur. A spur can vary in length from 1 m to 120 m (Figure 13.6). WebDevices are usually connected in a trunk-and-spur topology. System Manager head-end software and gateways are connected to the (Ethernet or RS-485) trunk network. Gateways then typically connect to RS-485 spur devices on each floor. Gateways manage traffic from the spur networks to the trunk network.
