Variable editor

Variables are declared in the Dictionary of the KAS IDE"Integrated development environment" An integrated development environment is a type of computer software that assists computer programmers in developing software. IDEs normally consist of a source code editor, a compiler and/or interpreter, build-automation tools, and a debugger main window.

The variable editor is a table that enables you to declare all variables of the application. Variables in the editor are sorted by groups:

global variables
"retain" non-volatile global variables
I/O variables (each I/O device is a group)
variables local to a program (including in and out parameters in case of a UDFB"User Defined Function Block" UDFB can be used as a sub-function block in another program of the application. It is described using FBD, LD, ST or IL language. Input / output parameters of a UDFB (as well as private variables) are declared in the variable editor as local variables of the UDFB).

Please refer to the description of variables in the language reference for a more detailed overview.

Each group is marked with a gray header in the variable list. The "-" or "+" icon on the left of the group header can be used to expand or collapse the group:
