Delete a variable

Delete variables from Dictionary instances to no longer use them in program organization units (POUs). Deleting a variable also deletes its instance in existing POUs.
TIP: Update each instance of a function or function block after adding, removing, renaming, changing data type, or changing direction of parameters in all POUs using the instance. Identify these POUs with the
Cross Reference Browser
, then open each POU and reselect the modified instance using the
Block Selector
.
To delete a variable
  1. From the
    Application View
    , access the Dictionary instance for the device or program organization unit (POU).
  2. Right-click the variable and click
    Delete
    .
