2 Operation
NOTE!
Variables that are stored via power off (retain variables) are not supported by all device types.
Variables and constants can be displayed and observed during debugging in the "Monitoring" tab. To do
so, they must be copied from the edit window or the "Variables" tab by dragging and dropping and pasted
into the "Monitoring" tab.
Pasting and removing is only possible if the program is not running. Different functions are then also
available via the context menu (right mouse button). With the function "New..." a new variable can be
added by entering a variable name (variable declaration may be required).
The user can assign alias names to system variables.

Debugging
The following variants are available with the Debug > Start debugging (menu bar) function:
• Cold start: A program that is already running on the device is terminated and the current program
from the ST editor is loaded onto the device. All variables (retain and non-retain variables) are reset
to their default values.
• Warm start: The retain variables are not reset.
• Service start: The program currently running on the device is used in the ST editor and can be ana-
lyzed. No variables are reset here. A prerequisite for the service start is that the code compiled in the
ST editor corresponds to the code on the device.
End ST editor
When ending the ST editor with Editor > Save and end (finish) (menu bar), there are the following options
(if debugging mode was active):
