After setting F_Dest_Add, enable security configuration in WoV and also in smartPad.
On SmartPad you can find it here: Configuration-->Security Configuration -->Robot Initial Startup -->Activate
If you are using a Siemens PLC, you must use a function block called ACK-GL in the TIA Portal. You can only give it a variable starting with I.
If this doesn't work then, you need to take the variable ACK_REI from the security database and set it to True.
Then you need to link the remaining errors you see on the smartPad in the PLC program and WoV on a field bus.
Thanks for your support! Yes i'm using a siemens PLC, I will code that too.
