6.11.3 Activate the interface (Modbus TCP server)
for energy management systems
The tasks described in this section may only
be carried out by a qualified electrician.
As of ECU firmware 5.12.x, it is possible for the char-
ging station to be controlled by an energy manage-
ment system.
Information on compatible energy manage-
ment systems and the description of the
Modbus TCP interface (Modbus TCP Re-
gister Table) can be found on our website:

u Navigate to the menu "Load Management" >
"Modbus" and set the following parameters:

If each charging station is to be controlled separ-
ately by an energy management system, the inter-
face must be activated in the web interface of each
charging station.
If the entire charging point network is to be con-
trolled by an energy management system, the inter-
face only needs to be activated in the web interface
of the DLM Master.
6.11.4 Activating the interface (EEBus) for energy
management systems
The tasks described in this section may only
be carried out by a qualified electrician.
As of ECU firmware 5.22, it is possible for the char-
ging station to be controlled by an energy manage-
ment system via EEBus.
