Product Overview

Hey everyone,today we’re discussing the ABB 3BHE021887R0101,officially known as the UBCC717BE101.It’s the core controller module in ABB’s Symphony®Plus and 800xA distributed control systems(DCS).Simply put,it’s the”CPU”of the entire control station,responsible for executing control logic,processing I/O data,and communicating with the host computer.In short,the stability of the system depends entirely on its durability.

This isn’t some small-time PLC;it’s a full-fledged,large-scale DCS controller designed for non-stop operations like power plants,chemical plants,and oil and gas platforms.Imagine a 600MW thermal power unit,where the boiler,steam turbine,and auxiliary equipment all rely on coordinated control.If one fails,the entire unit will be shut down,resulting in losses of millions per day.Therefore,the design of the 3BHE021887R0101 is simply this:stable!It supports controller redundancy,meaning two modules—one active and one standby—synchronize data in real time.If the active module fails,the standby module takes over within 0.05 seconds,potentially pre-empting the operator before the system has fully switched over.

Furthermore,it uses a high-performance 32-bit processor with ample memory and flash memory,allowing it to run complex control algorithms(such as coordinated control and advanced process control(APC))without any lag.It also offers a full range of communication interfaces,including Profinet for connecting to field devices,Modbus for interfacing with third-party systems,and Ethernet for connecting engineering and operator stations,providing a highly flexible network architecture.

Key Features and Advantages

The 3BHE021887R0101 module’s greatest strengths are its high reliability and availability.It supports hot standby.Two modules,installed in the same rack,synchronize programs and data in real time via a dedicated redundant bus.If the primary controller fails,the backup controller instantly takes over in less than 50 milliseconds,ensuring smooth operation without I/O output fluctuations and protecting field equipment.This level of redundancy is unattainable with standard PLCs.

Secondly,it boasts powerful processing capabilities.Its 512MB of memory is more than sufficient for running control programs,while its 1GB of flash memory can store extensive historical data and event logs.It easily handles complex computations,such as power plant coordinated control systems(CCS)or three-impulse drum water level control,with fast response times and high control accuracy.

Furthermore,it offers robust communication capabilities.Two Profinet ports can form a ring network,improving network reliability.The RS-485 port supports Modbus RTU,making it easy to connect to legacy equipment or third-party instruments.The Ethernet port supports standard industrial protocols,facilitating integration with operator stations,historians,and asset management systems,enabling plant-wide information integration.

Finally,it offers excellent compatibility and easy maintenance.As a standard controller for the ABB 800xA platform,configuration,downloading,and diagnostics are all performed using Control Builder M software,making it easy for engineers to get started.LED indicators on the module’s front panel clearly indicate power,operation,and redundancy status,eliminating the need for fuss or fuss.ABB’s global service network is also robust,ensuring 24/7 availability of spare parts and technical support.

In summary,the ABB 3BHE021887R0101 UBCC717BE101 is a mission-critical controller module engineered for the most demanding industrial environments.As a core component of the ABB Symphony®Plus and 800xA DCS platforms,it delivers exceptional reliability,high-speed processing,and seamless system integration.Its support for hot-standby redundancy ensures uninterrupted operation,minimizing downtime risk in power generation,oil&gas,and heavy industry applications.With robust communication capabilities including Profinet,Modbus,and Ethernet/IP,it enables efficient data exchange across the automation pyramid.Built to industrial-grade standards with comprehensive diagnostics and long-term support,the 3BHE021887R0101 is not just a control module—it’s a cornerstone of operational excellence and asset protection.

Application areas

The main battlefield of this 3BHE021887R0101 module is large-scale industrial automation systems.A typical example is a thermal power plant,where it coordinates everything from boiler combustion control,turbine DEH,feedwater deaeration,to the electrical system.A single 600MW unit might require several pairs of 3BHE021887R0101 modules for redundant control,ensuring complete safety.

Chemical plants also employ complex processes and numerous interlocking control systems for reactors and distillation towers,placing extremely high demands on the controller’s real-time performance and reliability.The 3BHE021887R0101 is ideal for this purpose.It is also commonly used in atmospheric and vacuum distillation units and catalytic cracking units in petroleum refining.

In the metallurgical industry,for example,automation systems for large blast furnaces and converters operate in harsh environments with high electromagnetic interference,where the module’s anti-interference capabilities and wide operating temperature range come in handy.The 3BHE021887R0101 is equally suited for applications requiring high-reliability DCS control,such as large pumping stations in water treatment plants and flue gas treatment systems in waste incineration power plants.
