4.3 OCPP backend
The charging station offers the option of being connected to a central man-
agement system via the Open Charge Point Protocol (OCPP). OCPP, as an
open application protocol, makes it possible to connect any central manage-
ment system to the charging station regardless of the manufacturer or sup-
plier.
When connecting to an OCPP backend, note the following:
● It is recommended that the master charging station on the network be
assigned a static IP address based on the MAC address of the device.
● Since the OCPP backend is usually not in the same network, the charg-
ing station must be assigned a "public IP address" which is routed to the
internal IP address (NAT).
● The firewall must be configured so that a communication between the
charging station and the OCPP backend is possible.
● For a connection via VPN, the IP address of the VPN must be specified
in the configuration for the downlink.
● In the case of a GSM connection, it may be necessary for the required
ports to be activated by the cellular service provider.
Ports for communication via OCPP
For communication with an OCPP backend, the following ports must be en-
abled in the network:
Port Protocol Definition Description

may only be located in the
range from 1025 to 65535.
● The selected port must be
configured on the charging
station.
