The Honeywell TDC 2000 and TDC 3000 are Distributed Control Systems (DCS) that use a communication network called the Universal Control Network (UCN) to connect various system components.
The UCN is a high-speed, token-passing bus network that allows for the exchange of data between processors, I/O devices, and operator consoles. It provides a reliable and efficient way to monitor and control industrial processes.
Here are some of the key features of the Honeywell UCN:
- High speed: The UCN can transmit data at speeds of up to 5 megabits per second.
- Reliability: The token-passing bus architecture ensures that all devices on the network have a fair chance to transmit data.
- Expandability: The UCN can be easily expanded to accommodate additional devices.
- Security: The UCN supports security features such as password protection and data encryption.
Honeywell's TDC 2000 and TDC 3000 DCS are legacy systems that are no longer in production. However, they are still in use in many industrial facilities around the world. Honeywell offers upgrade paths to migrate from TDC 2000/3000 to their current process automation system, Experion.
