Advant Fieldbus 100 Redundancy Concept The Advant Fieldbus 100 redundancy concept comprehends: • 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 bus lines as well as connections of stations to the bus. 1.8.1.1 Media Redundancy Media redundancy includes redundant cable and redundant modems. A media redundant AF 100 is built up as in Figure 1-1. The maximal difference in cable length between the redundant cables must be less than 1200 meters between any two stations throughout the whole bus.If the Advant Fieldbus 100 contains one or more of CI520, CI526, CI626, CI810 or PM810 (without the suffix Vx1 or y1) it is only possible use redundant coaxial media with a maximal difference, in cable length, of four meters between any two stations on the bus. You can not use redundant Twisted Pair or Optical media.

Communication Interface Redundancy

 Communication interface redundancy is achieved by using two CI522s connected to a media redundant bus. Communication interface redundancy is available for Advant Controller 400 Series. For connection of redundant communication interfaces, CI522s, to a twisted pair bus two TC516 modems are used, see Figure 1-2 (or four TC512). At connection to a coaxial cable bus four TC625 modems are required. The TC516 modem has two connections one for each redundant CI522 and a connection to one twisted pair bus cable. TC516 can be used for two redundant CI522s as well as for one single CI520V1/CI522/CI526V1.Redundancy in the S800 I/O Stations is achieved with redundant Field Communication Interfaces (FCIs) connected to a media redundant Advant Fieldbus 100. In the S800 I/O station redundancy is performed with redundant S800 communication interfaces sharing the same I/O modules. The redundancy is performed according to the same principles as communication interface redundancy in the Advant Controller 400 Series.
