Description

The CI840 Fieldbus Communications Interface
(FCI) is an intelligent communication interface
between a Controller via the PROFIBUS-
DPV1 fieldbus and the S800 I/O modules via
the ModuleBus.
CI840 is designed to be used in redundant
applications.
CI840 contains one PROFIBUS-DPV1
interface, two electrical ModuleBus interfaces,
LED indicators and a opto-isolated RS232
service port.
CI840 has isolated power converters that generates internal power for CI840 and
current limited +5 V supply for two electrical ModuleBuses.
Besides +5 V CI840 also distribute a current limited 24 V for the two ModuleBuses.
CI840 must be mounted on a Module Termination Unit TU846 or TU847. With
CI840 mounted on a TU847, only one electrical ModuleBus is connected. When
mounted on a TU846, two electrical ModuleBuses are connected.
