INDUSTRIAL AUTOMATION
Celebrating 50 Years of Honeywell DCS Innovation
Fifty years ago, Honeywell transformed industrial automation with the world’s first Distributed Control System. Across five decades, Honeywell’s DCS has led in industry firsts—shaping the future of automation.
The first Distributed Control System (DCS) was developed by Honeywell in 1975, with their TDC 2000 system. This system introduced a new approach to industrial control, moving away from centralized control and toward a distributed architecture. Honeywell filed the patent on Feb 3, 1975 and it was granted in January 1977.
- Shift from Centralized Control:
Traditional control systems relied on a single, large computer to manage all aspects of a process. This approach had limitations in terms reliability, scalability, and flexibility.
- Honeywell's TDC 2000:
The TDC 2000, released by Honeywell, was a groundbreaking system that distributed control functions across multiple modules, each handling a specific part of the process. This decentralized approach improved reliability, as a failure in one module wouldn't necessarily halt the entire system.
Key Features of the TDC 2000:
- Reduced Vulnerability: By distributing control, the TDC 2000 reduced the risk associated with a single point of failure in a centralized system.
- Improved Scalability: The modular design allowed for easier expansion and adaptation to changing process requirements.
- Enhanced Flexibility: The distributed architecture provided more flexibility in terms of process control strategies.
While Honeywell was first to market, other companies released DCS systems in 1975 as well.
These early systems laid the foundation for the modern DCS technology used in various industries today.
Here’s to 50 years of innovation; and to the next 50 led by Honeywell.
Because the future doesn’t just happen. The future is what we make it.
