Abstract
This chapter presents the syntax and semantics of the basic, common language elements of all programming languages of IEC 61131-3.
The syntax describes the language elements IEC 61131-3 makes available for its programming languages and how they may be used and combined with each other; their meaning is governed by the semantics.
The first section deals with the “simple language elements” which represent the basic elements of the languages.
“Data type definition” and “variable declaration” are then explained at length.
