System overview
The KeContact M20 enables control of multiple charging stations. The con-
nection is established over the IT network (switch/router). This makes charg-
ing with an intelligent load management possible. In combination with an up-
stream electricity meter, the entire charging network can be controlled dy-
namically (Modbus TCP).
Only one connection to backend systems is necessary (via OCPP). The
master (KeContact M20) is equipped with different network interfaces for
these functions.
