Local variables are declared between the keywords ‎VAR‎ and ‎END_VAR‎ in the declaration part of programming objects. You have read-only access to local variables (externally via the instance path).

The variable can be extended with an attribute keyword (‎CONSTANT‎, ‎RETAIN‎, or ‎PERSISTENT‎).

Example 

VAR
    iVar1 : INT;
END_VAR
