How do I select a bit value from a (status) byte?

Hello
is there also a way to adress bits of a integer directly like it is described here:
bit adressing codesys

I need to do a datatype conversion from single bits [switch] to 16 bit integer [number] because the modbus binding does not support datatypes <16 bit and I do not want to waste memory. See here:
Datatype Modbus TCP Binding

Thank you in advance.
