Declarations

Use the declaration editor for:

• assigning a program to a task

• creating (DUTs)

• declaring global variables

• declaring local variables

• declaring arrays

• creating function block instances

Variables can also be declared very comfortably in the POU body (using LD/FBD, ST/IL or SFC) or in the Variables pane.

Checking your declarations frequently with Object > Check will help you to find errors at an early stage.
