CI840A
Compact Product Suite hardware selector
S800 I/O is a comprehensive, distributed and modular process I/O
system that communicates with parent controllers and PLCs over
industry-standard field buses. The CI840 Fieldbus Communication
Interface (FCI) module is a configurable communication interface
that performs operations such as signal processing, gathering of
various supervision information, OSP handling, Hot Configuration
In Run, HART pass-through and configuration of I/O modules.
CI840 is designed for redundant applications. The FCI connects to
the controller by way of the PROFIBUS-DPV1 fieldbus. Module
termination units to use, TU846 with redundant I/O and TU847 with
non-redundant I/O.
