Pluggable safety key
The safety key must be inserted upon activation of the MOVISAFE
®
CS..A safety card
and may not be removed when the safety card is activated.
The parameterization data of the MOVISAFE
®
CS..A safety card is divided into appli-
cation-related data and the key data set. The key data set ensures the data integrity.
The application-related data is stored in the device. The application-related data is re-
leased with the aid of the key data set on the pluggable safety key. The safety card
becomes operational only if the key data set on the pluggable safety key matches the
parameterization.
The pluggable safety key is also used to establish a location reference in the system.
Since the application-related data set is released only with the matching key data set
on the pluggable safety key, the location reference can be established in this way. It is
the user’s responsibility to secure the location reference of the pluggable safety key in
the system. The data for safe communication is also stored on the pluggable safety
key, because this data has the same location reference. This ensures that, in the
event of a device replacement, the application-related data and the communication
data are available again immediately.
3.4
Identification and authentication
In the "Assist CS.." parameterization tool, unique identification of the device and an
authentication of the user is necessary for the steps "Parameterize", "Create report"
and "Confirm validation". To identify the device, enter the ID of the pluggable safety
key in the login dialog of the parameterization tool. The safety key ID is printed on the
safety key. As an alternative, the safety key ID can be read by the "Assist CS.." para-
meterization tool. To do this, the user must perform an identity verification using the
LED display of the device. This mechanism with the safety key ID ensures that the pa-
rameterization tool Assist CS.. is connected to the correct device. The user is authen-
ticated via the entry of a password.
3.5
Report and safety check
The acceptance report can be created once the parameters are downloaded. The ac-
ceptance of the safety card within the system can be carried out (see chapter "Re-
quirements for startup") with this acceptance report. Following acceptance, this must
be confirmed in the safety card. The confirmation is not a replacement for the test that
must be carried out. The "Checksum of the report" of the safety card is announced as
confirmation of the acceptance in the "Assist CS.." parameterization tool.

The MOVISAFE
®
CS..A safety card is an integrated, safe electronic assembly that
can be operated with or without a safe communication. PROFIsafe, FSoE, and
ISOFAST
®
are available for safe communication. MOVISAFE
®
CS..A is equipped
with safe inputs and outputs (F-DI, F-DO) and is available in the following designs.
