CI854BK01 3BSE069449R1

1. PROFIBUS DP/DP-V1 dual-mode master station
Class1 Loop Data: Periodically read and write real-time process data from DI/DO/AI/AO to meet the real-time requirements of closed-loop control
Class2 non cyclic data: online reading and writing of device parameters, fault diagnosis, calibration and debugging, without the need for shutdown
Compatible with all brands of Profibus slave stations: Siemens ET200 IO, ABB ACS frequency converter, various intelligent valve positioners, analyzers

2. Dual port bus line redundancy (core advantage)
Two Profibus channels can be connected to the same bus simultaneously, forming line redundancy; When a single cable is broken/short circuited, it switches without disturbance in milliseconds, without interrupting the control circuit, and is suitable for high safety working conditions in continuous production of thermal power and chemical industry.

3. Redundancy of the main station of the whole machine
Supporting paired configuration of two CI854BK01 modules, achieving overall redundancy of the Profibus master station, automatically switching to a backup card in case of main card failure, further enhancing system availability.

4. Full link fault diagnosis
Real time monitoring of bus short circuits, disconnections, missing terminal resistors, offline slave stations, and communication timeouts; Upload the fault code to the controller, use Control Builder M software to visually locate the fault point, and support online analysis of bus messages.

5. Online hot swappable maintenance
No need to shut down the entire controller, the module can be plugged and replaced separately without affecting other communication channels and control logic.

6. Multi module expansion
A single AC800M controller CEX backplane can mount up to 12 CI854BK01, expand multiple independent Profibus buses, and adapt to large-scale distributed measurement point scenarios.
