Siemens S7 v 5.5 configure fanuc profinet cp1616

Hi Guys 

I have some issues with profinet configuration 

Siemens step 7 v5.5 
Fanuc robot profinet card cp1616 

I have 8 byte safety 
16 byte DI
16 byte DO

I setup DI and DO. No error.
But I have  safety comm error 1.1 

I put Cp1616 at slot 0
safety at slot 1
DI at slot 2 
DO at slot 3

So far slot 2, 3 are ok, (no mismatch ) 

But safety are no ok, 
F number is matching between robot and plc side 

Is there’s anyone can help me on this, I don’t know what I miss. It’s the first time I am configure profisafe for robot 

Thanks
