4.15 Programming in accordance with IEC 61131-3 –
Safety-related example program
Once you have created the non-safety-related part of the example project, you can start cre-
ating the safety-related part.
4.15.1 Assigning/checking the PROFIsafe address (F-Address) of
PROFIsafe devices
The PROFIsafe address (F-Address) is a unique ID for each F-Device in the network. The
F-Host is assigned an F_Source_Address (F_Source_Add), while each F-Device is
assigned its own F_Destination_Address (F_Dest_Add).
You must set the PROFIsafe address via the DIP switches directly on the F-Device prior to
installation. Check the set F-Address in the project in PLCnext Engineer and adapt the set-
tings there, if necessary.
F_Source_Address
(F_Source_Add)
• Double-click on the controller node in the “PLANT” area.
The controller editor group opens.
• Select the “Safety Parameters” editor.
Figure 4-41 F-Address of the F-Host: F_Source_Add (F_Source_Address)
• In the “PROFIsafe addressing” view, check the setting for the F_Source_Add F-
Address. In the example, set F_Source_Add to “1024”. If necessary, adapt the value of
F_Source_Add to your application.
An adjustable range of “1 … 65535
dec
”, maximum, is permitted.
Unique F-Address assignment – Avoid addresses overlapping
Assign a unique F-Address to each F-Device that is used. In the example, the
AXL F PSDI8/4 1F is assigned F-Address “1” and the AXL F PSDO8/3 1F is assigned F-
Address “2”. Each F-Address assigned within a network must be unique and must not
overlap with other addresses.
For more detailed information on setting the PROFIsafe F-Addresses, please refer to
“Device identification/ number of safe devices” on page 27 and the device-specific user
documentation.
If you are not currently logged into the safety-related area, you will now be prompted to
enter the password in the “PROJECT AUTHENTICATION” dialog that opens (see “Project
login required” on page 103).
