Identification and authentication
In the "Assist CS.." parameterization tool, unique identification of the decentralized ba-
sic device and an authentication of the user are necessary for the steps "Parameter-
ize", "Create report" and "Confirm validation". To identify the decentralized basic
device, enter the ID of the memory module in the login dialog of the "Assist CS.." para-
meterization tool. The ID is printed on the memory module. As an alternative, the ID
can be read directly from the "Assist CS.." parameterization tool. To do so, the user
must perform an identify verification using the LED display of the decentralized basic
device.
These two identification procedures ensure that the "Assist CS.." parameterization tool
is connected to the correct decentralized basic device. The user is authenticated via
the entry of a password.
3.5
Report and safety check
The acceptance report can be created once the parameters are downloaded. The re-
port supports the safety-relevant acceptance required for the system (see chapter
"Startup requirements"). If the parameterization of the safety functions is changed, the
acceptance of the safety option must be confirmed. The confirmation is not a replace-
ment for the test that must be carried out. The "Checksum of the report" of the safety
option is announced as confirmation of the acceptance in the "Assist CS.." parameteri-
zation tool.

•
The MOVISAFE
®
CSB51A safety option is a safe electronic assembly integrated in
the basic device, which is operated with safe communication connection.
•
The MOVISAFE
®
CSB51A safety option can release or safely deactivate the out-
put stage of the basic device. The internal diagnostics functions at the F‑DO_STO
output require a stable state (stable "1" or "stable "0") for at least 2 seconds
(2.5 seconds with activated extended diagnostics) within 60 seconds.
•
The safety concept of the MOVISAFE
®
CSB51A safety option is based on a safe
state existing for all safe process values. With the MOVISAFE
®
CSB51A, this is
the value "0" for F-DO_STO.
•
The MOVISAFE
®
CSB51A safety option was designed pursuant to IEC 61508 for
SIL 3 and according to EN ISO 13849-1 for Performance Level e.
