Manipulating KUKA KRC4 safety values with PLC through El6695-1001

I'm trying to manipulate the reserved safety bits in Kuka KRC4 with Omron NX PLC with Kuka el6695-1001 as bridge.

Kuka KRC4 is connected to the primary, and the PLC to the secondary side of the EtherCAT bridge.
In the third image of the SmartPad, we can see that the communication is working, but the reserved bits does not update/match
The DTM file for Kuka should be correct

Thanks in advance!
