A Charge Point and the connected Wallboxes can have three different operating modes:

Only Basic Signalling
Only Basic Signalling is supported. Since electric vehicles using ISO 15118 can fall back to Basic Signal-
ling, they can charge, but without having the advantages of ISO 15118 communication.

Only ISO 15118
Only electric vehicles supporting ISO 15118 can charge.

Combined Mode
Both, Basic Signalling and ISO 15118 is supported. When a car is plugged into a Wallbox, the Charge
Point tries to establish an ISO
15118 communication. If this doesn't work, “Basic Signalling” will be used
for the communication after 30 seconds.
If the Operating mode of a Charge Point is "Only Basic Signalling" or "Only ISO 15118", all Wallboxes must
have the Operating mode "Only Basic Signalling" or "Only ISO 15118" respectively. If the Operating mode of
a Charge Point is "Combined mode", Wallboxes can have any Operating mode.
The ISO 15118 version used by Daimler's Smart III Electric Drive requires a security key (Network Member-
ship Key, NMK) to establish a communication link between the Wallbox and the electric vehicle. The Smart
III actually supports two NMKs, a public key for communication for example at a repair shop or for a public
Charging Station and a private key that can be stored inside the electric vehicle. A KeContact M10 has to be
configured to use either the public or the private NMK.
The following workflows are relevant for managing the Operating mode of a Charge Point:

Change the Operating Mode of a Charge Point
A KeContact M10 ships with "Combined mode" as the default operating mode. This operating mode can
be changed using the web user interface.

Change the Operating Mode of a Wallbox
If a wallbox is installed at a Charge Point, its operating mode will be initialized with the operating mode of
the Charge Point.
If the operator is not logged into the KeContact M10 or doesn't have the necessary access rights, the Login
screen will appear.
The Operating mode of the Charge Point can also be configured at the Installation screen.
