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 CI801 Fieldbus Communication Interface (FCI) module is a configurable communication interface that performs operations such as signal processing, gathering of supervision information, OSP handling, Hot Configuration InRun, HART pass-trough and configuration of I/O modules. The FCI connects to the controller through of the PROFIBUS-DPV1 fieldbus.

Features and benefits

• PROFIBUS DP PROFIBUS-DPV1 fieldbus interface.

• Supervisory functions of I/O ModuleBus

• Isolated power supply to I/O modules

• OSP handling and configuration

• Input power fused

• Hot Configuration In Run

• HART pass-through
