Fiber Optic Network
A networking technology in which data is transmitted through fiber optic cables as pulses of light.
Fieldbus
a general term for an industrial process network and protocols used to connect sensors, actuators and controllers together using simple cabling systems.
Hierarchical
arranged in layers, with higher layers being more sophisticated and performing more supervisory functions than lower ones.
Protocol
a set of rules for communication between two devices. using a common protocol allows communication between two devices. even if they are made by different manufacturers.
Server

TCP/IP
Transmission Control Protocol / Internet Protocol
tcp/ip
a family of communications protocols used to connect many different types of networked computers together. It is the protocol basis of the global internet.
What is the key to success in a process control?
Control
Five major components of DCS
Sensor and Actuators Conrollers Fieldbus Networks Building Networks Servers, work stations, and operator work stations
A modern DCS provides control over a large process through the the use of what?
lots of connected components
