10.2.3 Structure of the Variable Declaration Window
The variable declaration window consists of the overview of variables and of the variable detail
view.
After you have generated and opened a new code block, a default variable table is displayed. It
lists only the declaration types (in, out, in_out, stat, temp) permitted for the selected block, namely
in the prescribed order. You can edit the default variable declaration that is displayed after you
have generated a new OB.
Permitted data types of local data for the various block types are found under Assigning the Data
Typs To Local Data Of Code Blocks.
