The Main Window
4 Components of WAGO-I/O-PRO 32
4.1 The Main Window
The following elements are found in the main window of WAGO-I/O-PRO 32 (from top to bottom):
The Menu bar
The Tool bar (optional); with buttons for faster selection of menu commands.
The Object Organizer with register cards for POUs, Data types, Visualizations, and Resources
A vertical screen divider between the Object Organizer and the Work space of WAGO-I/O-PRO 32
The Work space in which the editor windows are located
The Message window (optional)
The Status bar (optional); with information about the current status of the project
4.1.1Menu bar
The menu bar is located at the upper edge of the main window. It contains all menu commands.

4.1.2 Tool bar
By clicking with the mouse on a symbol you can select a menu command more quickly. The choice of the available symbols automatically adapts itself to the active window.
The command is only carried out when the mouse button is pressed on the symbol and then released.
If you hold the mouse pointer for a short time on a symbol in the tool bar, then the name of the symbol is shown in a Tooltip.
In order to see a description of each symbol on the tool bar, select in Help the editor about which you want information and click on the tool bar symbol in which you are interested.
The display of the tool bar is optional (see 'Project' 'Options' category
Desktop).
4.1.3 Object Organizer
The Object Organizer is always located on the left side of WAGO-I/O-PRO 32. At the bottom there are four register cards with symbols for the four types
of objects
POUs, Data types,
Visualizations and
Resources. In order to change between the respective object types click with the mouse on the corresponding register card or use the left or right arrow key.
You will learn in chapter Managing Objects in a Project how to work with the objects in the Object Organizer.

The Main Window
4.1.4 Screen divider
The screen divider is the border between two non-overlapping windows. In WAGO-I/O-PRO 32 there are screen dividers between the Object Organizer and the Work space of the main window, between the interface (declaration part) and the implementation (instruction part) of POUs and between the Work space and the message window.
You can move the screen divider with the mouse pointer. You do this by moving the mouse with the left mouse button pressed.
Make sure the screen divider always remains at its absolute position, even when the window size has been changed. If it seems that the screen divider is no longer present, then simply enlarge your window.
4.1.5 Work space
The Work space is located on the right side of the main window in WAGO- I/O-PRO 32. All editors for objects and the library manager are opened in this area. The current object name appears in the title bar; in the case of POUs an abbreviation for the POU type and the programming language currently in use appears in brackets after it.
You find the description of the editors in the chapter The Editors
Under the menu item 'Window' you find all commands for window management.
4.1.6 Message window
The message window is separated by a screen divider underneath the work space in the main window.
It contains all messages from the previous compilations, checks or comparisons. Search results and the cross-reference list can also be output here.
If you doubleclick with the mouse in the message window on a message or press <Enter>, the editor opens with the object. The relevant line of the object is selected. With the commands 'Edit' 'Next error' and 'Edit' 'Previous error' you can can quickly jump between the error messages.
The display of the message window is optional (see 'Window' 'Messages').
4.1.7 Status bar
The status bar at the bottom of the window frame of the main window in WAGO-I/O-PRO 32 gives you information about the current project and about menu commands.
