Technical Specifications Back‑plane controller bus interface, PROFIBUS‑DP communication port. Auxiliary power 24 V DC, typical power consumption 4.7 W. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Supports standard PROFIBUS‑DP protocol.
Functional Features Works as PROFIBUS‑DP master station to communicate with multiple slave devices. Exchanges process data with 800xA controller via back‑plane bus. Uploads slave device status, measurement values and fault alarm data. Sends control commands and configuration parameters to field slave equipment. Front‑panel LED displays PROFIBUS‑DP bus link and module fault status. Built‑in hardware self‑diagnosis detects bus communication abnormality and internal hardware faults.
Application Scenarios PROFIBUS‑DP communication spare part for ABB 800xA DCS system. Applied in industrial sites requiring interconnection with PROFIBUS‑DP third‑party instruments and drives.
Performance Parameters High‑speed PROFIBUS‑DP bus data transmission. Supports multi‑slave device access. Accurate protocol parsing and data mapping performance.
Material Composition Flame‑retardant plastic module housing. Multilayer glass‑fiber epoxy printed circuit board. PROFIBUS‑DP protocol processing and signal isolation assemblies. Back‑plane plug‑in connector and PROFIBUS‑DP port.
Structural Characteristics Standard controller rack plug‑in module. Front side fitted with PROFIBUS‑DP port and status LED indicators. Rear side equipped with back‑plane bus connector. Weight approximately 0.44 kilogram.
Working Principle After power‑on, module loads slave configuration and completes PROFIBUS‑DP bus initialization. It cyclically exchanges input and output data with all field slave devices. Process data is transmitted to controller through back‑plane bus.
Installation Requirements Insert CI854A 3BSE030220R1 into corresponding rack slot and lock fixing latch. Connect PROFIBUS‑DP shielded bus cable to front‑end port. Ensure back‑plane connector is fully engaged. Restore power supply, import slave device configuration and verify cyclic data interaction.
Usage Notes Set correct bus address and baud rate matching field devices.Hot‑plug under powered state is strictly prohibited. Verify all slave device data status after module replacement.
