Simotion D435-2 PN -> 7 axes on Profisafe with STO function?

[onkel1]

Hey,
my problem is :
is there a possibility to establish profisafe connection between S7-315f-PN and Simotion D435-2-PN while using 7 drives/axes. All I need is STO function.

According to siemens documentation:
only 6 axes overall, while maximum 4 drives in 1 drive-cliq line to assure STO in deafult time. What if I will change the time, the max. number of drives will rise? Is there possibility to bypass this problem? Please help.
