Powerful Yet Simple Technology 

The Foxboro® Programmable Automation Controller (PAC) System is a high-performance automation controller and I/O subsystem integrated with easy-to-use Wonderware® software. Foxboro PAC hardware marries high performance, reliability and high I/O density with cost-effective redundancy options. The process modules and I/O system form the basis of a complete distributed control and recording environment capable of continuous analog, logic and sequential control combined with secure data recording at point of measurement; all designed to maximize return on investment (ROI). Because it is engineered with some of the most advanced, yet proven technologies available, the Foxboro PAC system is very powerful, yet so simple to use. 

Among its many capabilities, it offers stunning visualization and seamless integration between the hardware and software, alongside Eycon intelligent local display and control. In a nutshell, the Foxboro PAC System fully encapsulates the vast control, recording expertise and reputation that Invensys has built over the last 100 years. In addition, the Foxboro PAC System is an integral component of the InFusion™ Enterprise Control System. This allows for new possibilities of open integration and efficiency that spans production operations and business. 

The Foxboro PAC System is comprised of four primary components:

1. Foxboro PAC Hardware (T2750/T2550 Controllers and 2500 I/O, Eycon Intelligent Local Display and Control) 

2. ArchestrA System Platform (Historian, Information Server, Application Server and Device Integration)

3. Wonderware InTouch HMI Software 

4. Foxboro PAC Software (Integration software for Foxboro PAC Hardware, ArchestrA System Platform and Wonderware InTouch HMI Software)

Foxboro Helps Hydro Increase Aluminium Cold Melting Capacity and Reduce Waste & Emissions Goals:

• The company required a solution that would enable it to achieve increased melting capacity and reduce waste 

• The technology needed to not only increase production efficiency but also reduce production costs and increase energy savings Challenges: 

• The aluminium manufacturer needed to accurately control combustion operations and enable the smooth transition of various metallurgical processes 

• Optimizing energy output during the aluminium melting cycle was vital to achieving overall production efficiency 

• To maintain profitability, the technology needed to provide both cost savings in production as well as assist in minimizing the company's environmental impact Foxboro Solution: 

• Foxboro PAC System Results:

• By utilizing the key features of the Foxboro PAC system, Linde Gas has enabled Hydro to increase its aluminium cold metal melting capacity by more than 50 percent 

• The company was able to reduce dross to less than 2% and fuel consumption by 50% 

• A significant reduction in carbon dioxide and nitrogen oxide emissions was also achieved to maintain the company's commitment to reducing its impact on the environment 

• The Linde Gas Low Temperature Oxyfuel technology, using the Foxboro PAC System, now enables the continuous production of 125,000 tons of foundry alloys annually

Foxboro Helps RK Powergen Pvt. Ltd. Provide Clean, Reliable Electricity in India 

Goals:

• Support a biomass power plant that would generate clean power in an area that previously had limited and unreliable electricity 

• Automate plant operations to maximize efficiency and productivity while reducing downtime 

• Facilitate accurate control and monitoring of plant equipment to ensure consistent output and safety and security 

• Provide a solution that can be easily expanded as energy demands increase 

Challenges: 

• The plant had to meet strict requirements for sustainability, environmental monitoring and safety while conserving operating costs 

• The solution had to integrate various processes into one control solution that would encompass the entire plant 

• Operators needed real-time data to accurately control power generation, steam production and chilled water distribution 

Foxboro Solution: • Foxboro PAC System 

Results: 

• The plant provides electricity to local area residents and has improved local agricultural and industrial opportunities 

• Sustainability goals such as decreased air pollution, water conservation and optimized fuel consumption are being met through the solution's monitoring and control capabilities 

• Operators can now view plant-wide processes in real time, so they can react immediately and make changes to maintain power output and plan for maintenance
