System Overview
The ABB INFI90 is a legendary name in the world of industrial automation.It is not a single product but a full-fledged Distributed Control System(DCS)platform,designed and engineered by ABB to manage large,complex,and continuous industrial processes.As a seasoned expert,I can tell you that the INFI90 system was a technological marvel of its time,providing a scalable and highly reliable architecture that has stood the test of time.It consists of a suite of interconnected hardware modules,communication networks,and software,all working together to provide a robust control solution.
The core philosophy of the ABB INFI90 is distribution.Control functions,which might be centralized in a traditional PLC,are distributed across multiple controllers and I/O modules.This decentralized approach enhances system reliability and simplifies troubleshooting.For industries that have relied on the stability and performance of the INFI90 platform for decades,maintaining this infrastructure is a critical part of their operational strategy.A deep understanding of its architecture is essential for ensuring a plant’s long-term performance and protecting a significant capital investment.
System Architecture and Components
The ABB INFI90 system is built on a modular,distributed architecture.Here are its primary components:
Process Control Units(PCUs):These are the intelligent controllers that execute the control logic.Modules like the IMMFP12 and INNPM22 act as the brains of the system,handling algorithms and data processing.
I/O Modules:These are the eyes and ears of the system.Modules such as the IMDSI14(Analog Input)and IMDSO14(Analog Output)interface with field devices like sensors,transmitters,valves,and actuators.
Communication Network:The INFI90 system uses a high-speed network for communication between PCUs,I/O modules,and the operator station.This network,often based on the INFO-X protocol,ensures real-time data exchange and a cohesive system.
Operator Interface:This includes the human-machine interface(HMI)workstations where operators can monitor process variables,view alarms,and interact with the system.
This modular design makes the ABB INFI90 highly scalable,allowing a system to be tailored to a wide range of applications,from a small unit to an entire plant.
Main Features and Advantages
The ABB INFI90 DCS platform offers a number of key advantages that contributed to its long-standing success:
High Availability and Reliability:Designed for mission-critical applications,the INFI90 system is known for its incredible robustness.Its modular design and redundancy options for key components(like controllers and power supplies)ensure that a single point of failure will not lead to a system-wide shutdown.
Scalability and Flexibility:The modular nature of the INFI90 allows it to be easily scaled up or down.Users can add new I/O modules or controllers to expand a system without having to replace the entire infrastructure.This flexibility makes it a cost-effective solution for both new installations and retrofits.
Proven Technology:With decades of successful operation in the field,the INFI90 has a well-established reputation.Its performance in demanding environments has been validated time and again,providing a sense of confidence and security to plant operators.
Seamless Integration:The INFI90 platform was designed to work as a cohesive whole,with each module integrating seamlessly into the system architecture.This plug-and-play capability simplifies installation and commissioning,making it a favorite among engineers.
Application Field
