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.
Use Project
WOptions Category Build options to activate or deactivate nested comments.
FBD, LD and CFC allow comments to be entered for every network.
•
Find the network to be commented and select the command Insert ➞ ➞ ➞ ➞Comment.
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.
