2. Click on ‘New project ...’
🡆
The iCube Engineer user interface is opens.
3. At ‘Components’ select the corresponding safety CPU and drag&drop it onto the
‘Plant’‘Project’ .
🡆
To access the safety-related area, you must now assign a safety password.
■
Use strong passwords consisting of upper/lower case, numbers and special
characters.
■
The use of a password generator or manager is recommended.
■
The password in the templates of iCube Engineer is "safety".
Once the password is assigned, the CPU is added to your project.
4. Save your project via ‘File
🠂
Save as’ . Assign a meaningful name for your project
and close the dialog with [Save].
5.4.4 Parametrization of the safety parameters
NOTICE
There is a memory area on the CPU for safety variable assignments. Please
take the following limitations into account:
−
Each safety variable assignment, which is mapped into the process data,
occupies 16 bytes.
−
Each variable assignment, which is mapped into the process data, occu-
pies 8 bytes.
−
The total of all variable assignments, which are mapped into the process
data, must not exceed 19980 bytes.
NOTICE
Please note that the
‘FSoE device address’ or ‘F address’ of the local and
Ethernet-connected safety modules is unique and may only be assigned
once!
NOTICE
The parametrization of the safe parameters is protected by a safety password,
which you specified when creating the project. Ensure that the safety pass-
word is appropriately protected and only pass on the safety password to
authorised personnel!
NOTICE
Please note that the safety CPU generally supports 2-channel safety func-
tions. When designing the safety functions, take into account how far the
connected safety components provide 2-channel safety functions. There is no
information about this in the safety CPU. More information can be found in the
corresponding manufacturer documentation of the safety component.
2-channel capability is required to achieve SIL3/Cat.4/PLe. For SIL2/
Cat.3/PLd, 1 channel is sufficient. Please consider the specifications for
the test rate and request rate. Further information can be found in the
corresponding manufacturer documentation for the safety component.
