5.12  Setting the PROFIsafe address 
The PROFIsafe protocol is used to send safety message frames between the HMI device 
and the F-CPU. This means each station in the PROFIsafe communication must be 
assigned a unique PROFIsafe address. When the project is started, the HMI device is 
automatically logged on to the safety program. 
 
Unique PROFIsafe address required 
If more than one device is assigned the same PROFIsafe address, an emergency stop is 
triggered and the plant switches to the defined safe state. 
Assign a PROFIsafe address to the HMI device that is unique within the corresponding 
local network segment. 
 
Note 
PROFIsafe addresses must match 
For PROFIsafe communication to work, the PROFIsafe address of the HMI device must 
match the PROFIsafe address in STEP
 7. The PROFIsafe address 65535 is the default 
address for the HMI device 
in the delivery state.
