  • Selected: The variables in the Dictionary are filtered to display only those that are relevant to the PLC item currently selected in the project tree. Along with the Global, retains and variables related to the selected program or UDFB, structure definitions will be displayed. The dictionary content will change accordingly if another PLC program is selected in the project tree.
