Product Details

The CI541V1 3BSE014666R1 is a Profibus‑DP Interface Sub‑Card for ABB Advant OCS controller series, it belongs to compact Fieldbus Expansion Sub‑Module, which is inserted into the sub‑slot of main CPU board to expand Profibus‑DP fieldbus capability for the controller.

It adopts RS‑485 physical layer and supports Profibus‑DP protocol, which can be set as master or slave mode according to site requirements. It establishes deterministic real‑time data links between Advant controller and remote I/O stations, medium‑voltage drives, smart transmitters and third‑party PLC devices. The galvanic isolation design effectively eliminates ground‑loop interference and improves communication stability under heavy‑industrial noise environment.

LED indicators on front panel display bus activity, link status and communication fault information. Built‑in bus diagnosis function can detect short‑circuit, signal attenuation and frame error, and upload fault alarm to main controller via backplane bus. Engineers can complete bus parameter configuration through Advant programming tool to realize transparent data interaction between host system and Profibus‑DP peripheral equipment.

Sub‑module plug‑in structure saves independent rack slot resources. Widely used in thermal power, petrochemical, pulp‑paper and water‑treatment legacy Advant automation projects. It is practical communication hardware for Profibus‑DP device access, fieldbus network expansion and aging communication sub‑card replacement of old Advant OCS control systems.
