The ABB CI840 is a Fieldbus Communication Interface (FCI) module in the S800 I/O system, a modular and distributed process I/O solution. It communicates with parent controllers and PLCs using industry-standard fieldbuses, specifically PROFIBUS DP-V1.
This module is fully configurable and supports advanced functions such as:
-
Signal processing
-
Supervision information gathering
-
OSP (Output Signal Processing) handling
-
Hot Configuration In Run (HCIR)
-
HART pass-through
-
I/O module configuration
It is specifically designed for redundant applications and is connected to the control system via the PROFIBUS DP-V1 network.
Module Termination Units (MTUs):
-
TU846: For redundant I/O configurations
-
TU847: For non-redundant I/O configurations
