Functions
session to be started if an identification takes place by means of an RFID
card. The authorization function is enabled and disabled in the web interface
of the master charging station.
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. Up to
1000 RFID cards can be stored. After teaching in, the permitted RFID cards
are stored at the master charging station and are managed by the latter in
the charging network. It is not possible to teach in RFID cards at a slave
charging station.
When connecting to an external OCPP backend, all RFID cards must be
taught in at the OCPP backend. Any number of RFID cards can be stored. It
is not possible to teach in the RFID cards directly at a charging station.
The first 1000 RFID cards are relayed from the OCPP backend to the master
charging station where they are stored locally. This enables charging ses-
sions to be authorized even if the connection fails temporarily. In case of a
connection failure, authorization requests, depending on the authorization
mode, are compared to the locally stored RFID cards.
5.2.1 Authorization modes
The authorization modes described below are available in the web interface
if the authorization function has been activated.
Online Authorization Mode
This defines which storage location an authorization request is to be com-
pared to.

higher-level OCPP backend fails.

Mode
The authorization request is first compared to the locally stored
RFID cards stored at the charging station. If the RFID card is
not stored locally and an OCPP backend is used, a comparison
takes place with the RFID cards stored at the OCPP backend.
If no OCPP backend is used, this setting must be used for an
authorization to be active.
The authorization request is always compared to the RFID
cards stored on the OCPP backend. There is no comparison to
the locally stored RFID cards stored at the charging station.
Mode
All RFID cards are accepted, even if they are not stored locally
at the charging station. Only those RFID cards that are stored
locally at the charging station and have a status other than "AC-
CEPTED" are rejected.
Only RFID cards stored locally at the charging station with the
status of "ACCEPTED" are accepted.
