Machine data Value to be entered Property in the TIA Por‐
tal
MD10389[0..47] Outputs of the F-DO modules
$MN_PROFISAFE_OUT_ASSIGN.
For
example, enter "1004" when OUTSE/OUTSEP 1 to
4 is used.
-
MD10098 Factor for PROFIsafe cycle
$MN_PROFISAFE_IPO_TIME_RATIO
The PROFIsafe cycle is displayed in MD10099 and is
constructed as follows:
MD10098 (factor for PROFIsafe clock cycle) x
MD10071 (IPO clock cycle)
The value should lie between 16 ms and 24 ms.
-
The sequence and the index entered for the PROFIsafe addresses is irrelevant.
3.
Restart the NCK.
4. Check the enabled input bytes in DBB 138 "Profisafe input bytes". One bit must be set for
each byte.
5. Check the enabled output bytes in DBB 140 "Profisafe output bytes". One bit must be set for
each byte.

10.7.8 Parameterizing PROFIsafe telegrams
The modules and submodules to be configured must be selected individually in order to make
the desired settings in the "Properties" inspector window. You can select the modules and
submodules in the device view or device overview (in the case of GSD-based devices, only in
the device overview).
You can set the I/O addresses in the properties of the telegrams. These I/O addresses must lie
within the process image of the PLC. (Default setting: 1024 bytes; can be configured under
"Cycle" in the PLC properties.)
You can select telegrams in the device view or device overview of the rack.
