When you have connected to the CPU, STEP 7 turns the headers of
the work areas orange.
The project tree displays a comparison of the offline project and the
online CPU. A green circle means that the CPU and the project are
synchronized, meaning that both have the same configuration and
user program.
Tag tables show the tags. Watch tables can also show the tags, as
well as direct addresses.
To monitor the execution of the user program and to display the values of the tags,
click the "Monitor all" button in the toolbar.
The "Monitor value" field shows the value for each tag.

open editors without having to open or close the editors.
In the toolbar of the program editor, click the "Monitoring on/off" button to display the status
of your user program.
