cannot run the free function blocks

Hello there,

I tried to use a free function block in sinamics s110 but i couldn't succeed.

in my work i assigned two digital inputs (X130.1 - X131.4) to OR 0 logic gate but i couldn't read the logic 1 value at the output even i hit the buttons.

Under the I/O list i can see that my signal is received to the CU305 but output were not turned into logic 1.

i set the run-time group to the run-time group[0] also. is that about the run sequence or run-time group assignment?

you can see the signals and the assignments in the attachments.

what can i do to be able to run it.

thanks in advance.

Activating the run-time group? 

I was reading the manual but i haven't see that. Can you please tell me how can i activate that.

edit: And is it possible to give me a short information about how blocks are depend on the sampling time. 

Thank you for the warning.

i set the p20000[0]= 4*r20002 which means T=1ms

and it worked.

still, further information about the sampling times and hardware/software basis samoling times would be great for me.

thank you so much again.
