Opening a Data List

Double-click the respective node in the PLANT and open the Data List in the editors area.
The first example shows the resource-global Data List of the controller ('IEC 61131-3' node).

The second example shows how to open the Data List of a program instance. This is only possible if the respective POU instance contains instance-related located variables. Such variables result from program-global variables or local FB variables which are declared with a set data direction (variable property 'I/Q') in the POU type.
