Assignment of the PROFIsafe address
PROFIsafe address
Every fail-safe module has an own PROFIsafe address. Before installing fail-safe modules,
you must set the PROFIsafe address on each F-module.
PROFIsafe Address Assignment
The PROFIsafe addresses (F_source_address, F_destination_address) are assigned
automatically when you configure the fail-safe modules in
STEP 7.
You can view the F_destination_address in binary format in
HW Config in the Object
properties of the fail-safe modules in the "DIP switch setting" parameter. You read the
PROFIsafe address from the parameter assignment dialog box and set it on the fail-safe
module using the address switch.
You can edit the configured F_destination_address in
HW Config. To prevent addressing
errors, however, we recommend that you use the automatically assigned
F_destination_address.
Address Switch for Setting PROFIsafe Addresses
The address switch (10-pin DIP switch) is located on the left-hand side of every fail-safe
module. Use this address switch to set the PROFIsafe address (F_destination_address) of
the F-module.
Note
Fail-safe modules in ET 200S can only be operated in safety mode.
Setting the Address Switch
Before installing the F-module, ensure that the address switch is set correctly.
Valid range of the PROFIsafe addresses: 1 to 1022. The figure below shows an example of
an address switch setting.
