The CI810 Fieldbus Communications Interface (FCI) is an
intelligent communication interface between a controller
via the Advant Fieldbus 100 fieldbus and the S800 I/O
modules via the ModuleBus.
CI810 has four basic parts: Module termination board,
power supply board, processor board and the fiber optic
ModuleBus module (see block diagram).
The power supply board has an isolated power converter
that generates a short circuit proof +5V supply for the
CI810 and I/O modules. It also contains opto-isolated
RS232 drivers/receivers for the service port.
The Processor board contains the CPU, RAM, Flash
PROM, ModuleBus interfaces, Advant Fieldbus 100
protocol chip, LED indicators and two rotary switches for the units AF100 station address.
The termination board is a unit where most of the connections to the outside takes place. It is
grounded to the DIN-rail through a metallic spring connector. The board carries screw terminals for
