personnel.

The reader is assumed to be familiar with the Advant Controller 70,

Advant Controller 110, Advant Controller 400 Series, AC 800M controller,

S800 I/O Stations and/or AC 100 OPC Server, the relevant data base elements, and

the Advant Station 140 Engineering Station. For further information, see Table 2.

Document Conventions

In this document, the AF 100 units are generally named without suffix Vx or A

unless it is necessary for the functionally described. CI810 is the general term for

CI810/CI810V1/CI810V2/CI810A.

For example, if media redundancy is described, and the description for S800 Field

Communication Interface (FCI) states that the unit to use is

CI810V1/CI810V2/CI810A or CI810V1, it implicitly includes CI810V2/CI810A.

For verification, refer to Table 6.

Microsoft Windows conventions are normally used for the standard presentation of

material when entering text, key sequences, prompts, messages, menu items, screen

elements, etc.

Overview

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).

Communication Interface Redundancy

Communication interface redundancy is achieved by using a pair of CI522s, CI630s,

CI631s, CI869s or CI820s, connected to a media redundant bus. Communication

interface redundancy is available for Advant Controller 400 Series, Advant

Controller 160, AC 800M controller, and S800 I/O stations.

Two communication interfaces (CIs) can operate as a pair, where one is Primary and

the other is Backup in the controller configuration.

Functions of Primary CI

In a redundant configuration, the address of the primary CI is the configured station

address on the bus.

The primary CI:

•Sends all output CDPs.

•Receives all input CDPs.

•Sends the time synchronization message if the station is configured as time synchronization master.

•Handles the normal Service Data communication for the station.

•Supervises that the backup can send on the bus. This is done at a low frequency using the service data protocol.

•Must be configured as bus master if the module is CI522/CI630 or CI631, so that the bus master responsibilities are performed
