In the case of a local charging network without a higher-level OCPP back-
end, all RFID cards must be taught in at the master charging station and the
authorization function activated via its web interface. Up to 1024 RFID cards
can be stored. After teaching in, the permitted RFID cards are stored at the
master charging station and are enabled by the latter throughout the entire
charging network. It is not possible to teach in RFID cards at a slave charg-
ing station.
When connecting to an external OCPP backend, all RFID cards must be
taught in at the OCPP backend and the authorization function must be acti-
vated. Any number of RFID cards can be stored. It is not possible to teach in
the RFID card directly at a charging station.
Behavior in the event of connection failures
In order to be able to temporarily authorize charging sessions in case of con-
nection failures, the following behavior has been implemented:
The first 1024 RFID cards are relayed from the OCPP backend to the master
charging station where they are stored locally. If the connection to the
higher-level OCPP backend terminates, the master charging station autho-
rizes these stored RFID cards throughout the network until the connection is
reestablished.
In addition, the first taught-in 20 RFID cards are relayed from the master
charging station to each slave charging station. If the connection to the mas-
ter charging station is terminated, these stored RFID cards are authorized by
the individual slave charging stations until the connection is restored.
4.2.1 Displays and signals
During RFID authorization, the charging station can display different light
patterns on the LED bar and emit acoustic signals.
