In an automated process the control system must communicate with every controlled component and every transmitter.

Examples of the types of signals between the control system and the process which it controls are:

    • output (command) signals which actuate components in the process;
  • input (feedback) signals from valves and motors which inform the control system that the component in question has been actuated;

These signals are processed by the logic unit of the control system.
