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:
