A pragma is a text in the source code of the application that is enclosed in curly brackets. Pragmas are used to insert special statements in the code, which the compiler can evaluate. This allows a pragma to influence the properties of one or more variables with respect to precompilation or compilation (code generation). Pragmas that the compiler does not recognize are passed over as a comment.

The statement string of a pragma can also extend over multiple lines.

For more details about the syntax, see the descriptions of the individual CODESYS pragmas.

There are different pragmas for different purposes (example: initialization of a variable, monitoring of a variable, adding a variable to the symbol configuration, forcing the display of messages during the compilation process, and behavior of a variable under certain conditions).

NOTICE

Uppercase and lowercase characters have to be respected.
