Page 9: Topologies
Installation GEREM104.CDR Figure 1.4 - Fieldbus Network Topologies Almost any topology is possible. It is mainly a matter of where the terminator is connected. • Bus • Tree (Chicken-foot) • Daisy-chain • Point-to-point As far as fieldbus is concerned that are all alike, what matters is the placement of the terminator. -
Page 10: Bus Topology
Foundation Fieldbus Series 302 – Installation, Operation and Maintenance Manual Bus Topology Devices are distributed along the trunk connected through spurs. A spur may be up to 120 m long. GEREM105.CDR Figure 1.5 - Bus Topology Tree topology A main trunk runs from the control room into the field where it branches out to the individual devices. -
Page 11: Daisy Chain Topology
Installation Daisy Chain Topology Cable is chained from device to device. It is important to ensure that a device may be disconnected without other devices also being disconnected. Therefore make sure to use same conduit for ”in” and “out” wires in order to enable removal of device without interrupting bus. -
Page 12: Point-To-Point Topology
Foundation Fieldbus Series 302 – Installation, Operation and Maintenance Manual Point-to-Point Topology Only two devices connected to each other. This topology does not take advantage of the multidrop capability of fieldbus. Typically used only on workbench with device and notebook computer. -
Page 13: Device Quantity
Installation Device Quantity Rules of thumb: 32 separately powered or 12 bus-powered plus an interface. 4 per safety barrier in hazardous area (one fieldbus network may have many barriers). More or less devices may be possible depending on wire size and length, power consumption and barrier rating. -
Page 14: Terminator Placement
Foundation Fieldbus Series 302 – Installation, Operation and Maintenance Manual Terminator Placement The terminator should be placed at each end of the trunk. The power supply impedance PSI302 has one of the terminators built in. In bus topology the end of the trunk is easy to see. In tree topology the end of the trunk is where the spurs branch out. -
Page 15: Redundant Power
Installation Redundant Power Automatic bumpless switchover between redundant power supplies. Only one PSI302 should have the terminator connected, or a separate power supply-end terminator is used.
