This standard contains graphic symbols for representing logic functions or physical devices capable of carrying out logic functions. Descriptions of logic functions, the graphic representation of these functions, and examples of their applications are given. The symbols are represented in the context of electrical applications, but most may also be applied to nonelectrical systems (for example, pneumatic, hydraulic, or mechanical).
