OPC Client DA/UA with all bit

Hello,

Thank you for this video.
But I still have a probleme with the OPC Client DA/UA.
When I select FestoDidactic.EzOPC.1 as server.
I have only the representation of the bytes and not each bit (print screen in attachement).

How can I configurate the OPC Client DA/UA to have each bit visible in order to assign the sensors and actuators?
