Requirement: A programming object (POU or GVL) of a project is open.

  1. Click “Edit  Auto Declare”.

    The “Declare Variable” dialog opens.

  2. Select the desired scope for the variable from the list box “Scope”.

  3. Specify a variable name in the input field “Name”.

  4. Select the desired data type from the “Data type” list box.

  5. If the initialization value deviates from the standard initialization value, enter an initialization value for the variable.

  6. Click “OK” to confirm your input.

    CODESYS lists the recently declared variable in the declaration part of your programming object.

With the help of pragmas in the declaration part you can affect the processing of the declaration by the compiler.
