Twincat 3 O2T register error

I have a UR5e Robot communicating over PROFINET. I can access the device in Twincat 3 and the PROFINET LED in the Fieldbus menu is also Green on the Robot. However, in Twincat 3 under the Profinet API all my 02T Output registers are in a BYTE format. This makes me unable to communicate with the robot. I am aware that you have a UDT file that reformats these registers and turns them into BOOL, INT, FLOAT registers in a Siemens environment.
How can I achieve the same in Twincat 3 with a Beckhoff IPC ?
