7.2.18 Declaration editor in online mode

In online mode, the declaration editor is a monitor window.

Every line contains a variable followed by an equal sign (=) and the variable value.

• Three question marks (???) will appear if the variable has not been defined yet.

Multi-element variables

Multi-element variables are identified with a plus sign.

• Press <Enter> or double-click the variable to open it and to list all components. The variable

will then be identified with a minus sign.

• Double-click or press <Enter> again to hide the components and to return the plus sign.

Single-element variables

Press <Enter> or double-click a single-element variable to open the dialog box for writing a variable.

The current variable value can be changed by entering a new value. In the case of Boolean variables,

the value will be toggled without dialog box display.

The new value (now represented in a different colour) will not be written to the control immediately.

• Thus any number of variables can be modified and then written to the control in one go

(cycle-consistent).

7.2.19 Comment

User comments must start and end with the special character sequences (* and *).

Comments are allowed in all text editors and there at any location, such as declarations, IL and ST

and user-defined data types.

In SFC, comments for the step can be entered under

Edit step attributes

Tip!

Positioning the mouse pointer briefly over a variable in online mode will display a tool tip with the

variable’s type and any comments.

Only the variable type is displayed in offline mode.
