'Extras' 'Properties...' in CFC
Constant input parameters (VAR_INPUT CONSTANT) from functions and function
blocks are not shown directly in the continuous function chart editor. These can be
shown and their value can be changed when one selects the trunk of the block in
question and then selects the command ‚Extras' ‚Properties' or simply double clicks on
the trunk. The „Edit parameters" dialog opens:
Properties dialog
The values of the constant input parameter (VAR_INPUT CONSTANT) can be changed.
Here it is necessary to mark the parameter value in the column Value. Another mouse
click or pressing on the space bar allows this to be edited. Confirmation of the change
to the value is made by pressing the <Enter> key or pressing <Escape> rejects the
changes. The button OK stores all of the changes which were made.
Note!
This functionality and the associated declaration of variables with keyword
"VAR_INPUT CONSTANT" is only of impact for the CFC editor. In the FBD editor
always all INPUT variables will be displayed at a box, no matter whether declared as
VAR_INPUT or VAR_INPUT CONSTANT. Also for text editors this does not make any
difference.
Selecting elements in CFC
One clicks on the trunk of the element to select it.
To mark more elements one presses the <Shift> key and clicks in the elements
required, one after the other, or one drags the mouse with the left hand mousekey
depressed over the elements to be marked.
The command 'Extras' 'Select all' marks all elements at once.
