Information
If no OCPP backend is used, the "FirstLocal" authorization mode must be set for authorization to be
active.
*) The first 1000 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 fails, the master charging
station authorizes these stored RFID cards throughout the network until the connection is
reestablished.
4.2.2.
Displays and signals
During RFID authorization, the charging station can display different light patterns on the LED bar and
emit acoustic signals.
