Virtual unplugging of devices from the configuration
STEP 7 provides a storage area for "u
n-
plugged" modules. You can drag a module
from the rack to save the configuration of
that module.
These unplugged modules
are saved with your project, allowing you
to reinsert the module in the future without
having to reconfigure the parameters.
One use of this feature is for temporary
maintenance. Consider a scenario where
you might be waiting for a replacement
module and plan to temporarily use a di
f-
ferent module as a short
-term replace-
ment.
You could drag the configured
module from the rack to the "Unplugged
modules" and then insert the temporary
module.
