Description

The ABB UFC911B106(manufacturer part number:3BHE037864R0106)is a central processing unit(CPU)module from ABB’s AC 800M programmable logic controller(PLC)family—a core component of the ABB Ability™System 800xA distributed control system(DCS).Designed for mission-critical industrial automation,this controller delivers high-speed deterministic control,robust communication,and seamless integration across process,power,and discrete applications.

Based on the PM511 processor platform,the UFC911B106 features 106 MB of application memory,enabling complex control strategies,data logging,and integration with higher-level systems.It supports IEC 61131-3 programming languages(LD,FBD,ST,SFC)via ABB Control Builder M,and includes built-in Ethernet(for 800xA connectivity),RS-232 service port,and optional Profibus DP master/slave capability via integrated or add-on modules.

The unit is suitable for non-redundant or redundant configurations(when paired with a second CPU and synchronization link),making it ideal for applications requiring high availability—such as boiler control,water treatment,conveyor systems,and substation automation.It is certified for use in SIL 2 safety applications per IEC 61508 when implemented with appropriate safety libraries and architecture.

Application Scenarios

At a municipal wastewater plant in Germany,two ABB UFC911B106 controllers manage aeration basins and sludge dewatering in a hot-standby redundant setup.During a lightning strike that disrupted one controller,the backup took over in<50 ms—preventing overflow and regulatory violations.The integrated Ethernet allowed operators to monitor the failover event in real time via System 800xA,while historical data from the 106 MB memory aided root-cause analysis.

Technical Principles and Innovative Values

Innovation Point 1:Unified Architecture–Bridges process automation and power control within a single 800xA environment.

Innovation Point 2:Deterministic Real-Time Performance–Sub-millisecond response for fast interlocks and motor sequencing.

Innovation Point 3:Seamless Redundancy–Automatic state transfer ensures zero logic loss during failover.

Innovation Point 4:Open Connectivity–Native support for Modbus TCP/RTU,Profibus,and OPC UA simplifies integration with third-party devices.

Application Cases and Industry Value

In a Chilean copper mine,UFC911B106 controllers automate conveyor belt networks spanning 12 km.The fast scan cycle enables precise anti-jam logic,reducing unplanned downtime by 35%.In parallel,the same controllers interface with ABB variable speed drives via Modbus TCP—optimizing energy use.

Similarly,a U.S.hospital uses this CPU in its emergency power system to sequence generator start-up,load shedding,and retransfer—ensuring NFPA 110 compliance during grid outages.
