3-6 SINUMERIK 840C, OEM Version for Windows (BA)
3.3 Operations with windows
When you work with different applications, you will often have several
windows open simultaneously on the screen. The window in which you are
currently working and where you can enter data is known as the active window.
You can switch between different windows (= applications) in the following
way.
Fig. 3-3 The Task Manager of the SINUMERIK 840C
Applications in MS-Windows are normally started from the Program
Manager. On the SINUMERIK 840C, the Area Switchover performs this
task. However, when the Area Switchover is used to select an application that
is already running in the background, it simply brings that application into the
foreground instead of starting a second instance. This procedure only applies to
standard Siemens applications, not to general MS-Windows applications.
Hidden applications, i.e. applications running in the background, can be
brought into the foreground using the Task Manager. In MS-Windows it is
activated by simultaneously pressing the <ALT> and <TAB> keys on the MF2
keyboard. By holding down the <ALT> key and repeatedly pressing the
<TAB> key you can select the individual applications and bring them into the
foreground.
