5.2.2

Example: Interface to the S7 safety program

When you configure the hardware in STEP 7, you assign the control word and status word in
the PROFIsafe profile of the inverter to specific output and input addresses of the SIMATIC
controller. In section Configuring PROFIBUS communication with telegram 30 via GSD
(Page 78), start address 14, for example, was assigned. This results in the following
assignments between the I/O addresses and inverter signals for this example:
80
①
F_Dest_Add
Note the value of this address. You require this value when commissioning the safety
functions.
②
F_WD_Time
Set a value which is greater than the cycle time of your safety program.
If your safety program is called every 150 ms, for example, in OB35, set the value of
F_WD_Time to 200.
