Description

The CI830 Fieldbus Communications
Interface (FCI) is an intelligent
communication interface between a
Controller via the PROFIBUS-DP fieldbus
and the S800 I/O modules via the
ModuleBus.
CI830 has four basic parts: Module
termination board, power supply board,
processor board and the optical port (see
block diagram).
The power supply board has an isolated
power converter that generates a short circuit
proof +5 V supply for the CI830 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,
PROFIBUS-DP protocol chip, LED indicators and two rotary switches for the units
PROFIBUS 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 power supply and redundant power supply monitoring,
