Distributed Control Systems
A Distributed Control System (DCS) is a control system for a process where the individual control elements are not localized. The system is made up of several control elements organized into a hierarchy which are all connected to a central communication system for monitoring and control. When building a DCS system, it is important to consider all aspects of the system, from the I/O to the PLC and the supervisory HMI. DCS systems often use a central PLC connected by network cables to nodes which contain I/O devices such as: fieldbus couplers, I/O slices (usually input/output, or digital/analog), and terminal blocks.
A Fieldbus is an industrial computer network system used for real-time distributed control of industrial machines. Programmable Fieldbus Controllers are typically used to connect multiple devices within a manufacturing plant. The four basic fieldbus networks are: sensor bus networks, device bus networks, control bus networks and enterprise bus networks. Fieldbus networks allow for daisy-chain, star, ring, branch, and tree network topologies.
Wago Distributed Control System Products:
Electromate supplies a full family of Fieldbus Programmable Controllers, I/O Systems, Interface Electronics, and Electrical Interconnect Products from WAGO. WAGO Fieldbus DCS products offer security, dependability, high quality performance and versatility. They can be used in a variety of applications and industries. Production lines are a common application since fieldbus DCS products can connect a variety of input and output devices. Instead of hardwiring each individual device in a production line to one machine, a fieldbus DCS connects all of the product line devices together by running one connection the length of the entire machine.
Fieldbus DCS products are used in many industries, including, but not limited to:
- Trains and Rail Infrastructure
- Pharmaceutical and Medical
- Building Automation
- Food & Beverage and More
