Delete Variables from the Variable Selector

Deleting variables from the Variable
Selector
also removes these variables from the dictionary instance for the program, controller, or device.

IMPORTANT: The preferred method to create variables is from dictionary instances to avoid potential mistakes like inserting a variable in an unintended scope.

To delete a variable

Access the Variable
Selector
by doing one of the following:

For graphical POUs (FBD or LD), drag an element requiring the selection of a variable, like a variable, coil, or contact. The Variable
Selector
displays (when the Automatically
invoke
the
Variable/Block
Selector
option is set to True). Also double-click an element in the language container to invoke the Variable
Selector
.

For textual POUs (ST), right-click in the language container, and then click Variable
Selector
(Ctrl+I).

When mapping variables for communication protocols, click Add
Variable
or vrs_vrs2

In the variables grid, right-click the variable to delete, and then click Delete
.
