Status bar[edit]

The status bar displays: the controller for which the current function diagram is designed, the status of communication with the controller, the presence of system software and function diagram in the connected controller. In the simulator mode the status bar displays information about controller resources used by the user diagram.

Function blocks in this panel are grouped by their purpose and, depending on display setting, may be presented as either icons or a list. Scroll the function block panel by using the vertical scroll bar or your mouse wheel.
