distributed control system (DCS)

A type of automated control system that is distributed throughout a machine to provide instructions to different parts of the machine.

Instead of having a centrally located device controlling all machines, each section of a machine has its own computer that controls the operation.

For instance, there may be one machine with a section that controls dry elements of cake frosting and another section controlling the liquid elements, but each section is individually managed by a DCS.

A DCS is commonly used in manufacturing equipment and utilizes input and output protocols to control the machine.
