Advant Fieldbus 100 (AF 100) is a high performance fieldbus, which is used for: • Communication between Advant Controllers • Communication between Advant Controllers and S800 I/O Stations, AC 800M controllers, AC 100 OPC Server, and the equipments developed and sold by other ABB companies. In an AF 100 bus, it is possible to reach up to 80 stations within a total physical distance of up to 13300 meters (43300 feet). Advant Fieldbus supports three transmission media: • Twisted pair (Twp) • Coaxial (RG59 and RG11) • Optical media. An AF 100 bus can be built up with all the three media, where a part of one kind of media is a specific segment.

The following rules apply to the segments: 

• To each twisted pair segment, 32 stations can be connected, and the maximum segment length is 750 meters (2500 feet) • The coaxial segment can be: – 300 meters (1000 feet) with cable RG59 or – 700 meters (2300 feet) with cable RG11. • The optical media is only used in point-to-point communication, and it allows the total length of a bus segment to be up to 1700 meters (5500 feet). • If back-to-back coupled optical segments are used, it is possible to reach up to a physical length of 13300 meters (43300 feet).

Advant Fieldbus 100 Redundancy Concept 

The Advant Fieldbus 100 redundancy concept contains: • Media redundancy • Communication interface redundancy • S800 I/O Field Communication Interface redundancy. When redundant media is used, redundancy must be maintained through the whole bus (this comprises of the bus lines as well as connections of the stations to the bus).An Advant Fieldbus 100 may be installed with one or two physical bus lines (single or redundant media). Two bus lines are chosen when increased availability is required. The redundant bus line does not enhance the bus bandwidth when both the bus cables are operating.

Media Redundancy

 The Media redundancy includes redundant cable and redundant modems. A media redundant AF 100 is configured and connected as in Figure 1. The maximum difference in cable length between the redundant cables must be less than 1200 meters between any two stations throughout the whole bus.
