Communication Section 2 Product Description
30 3BSE015969-600 A
Advant Fieldbus 100 with redundancy
Redundancy on Advant Fieldbus 100 includes redundant cable, redundant modems
and redundant CI820/CI820V1 FCI together with the interconnecting unit TB815.
Communication
S800 I/O uses Advant Fieldbus 100 or PROFIBUS as an external communication
interface and ModuleBus as an internal communication link between clusters and
their I/O modules.
Advant Fieldbus 100
S800 I/O is connected to Advant Fieldbus 100 via twisted pair segment. When
connected to Advant Fieldbus 100, the communication interface module and its
S800 I/O modules are called as S800 I/O station.
An S800 I/O station works as a slave
for one parent controller. If several S800 I/O
stations are connected to the same Advant Fieldbus 100 together with more than one
controller, each S800 I/O station needs its own dedicated parent controller. 
