The present disclosure relates to a function connection unit for connecting functional modules. The functional connection unit includes a plurality of functional module terminals configured to connect to the functional modules and to communicate according to a first communication protocol, and a parameter memory that includes parameter data for device specific parameterization of at least one functional module. The parameter memory is configured to connect to a functional module terminal of the plurality of functional module terminals. The function connection unit is configured to read the parameter data from the parameter memory. The function connection unit is also configured to parameterize at least one functional module in a device-specific fashion based at least in part on the read parameter data.
