Meter unit and control system with meter unit

A meter unit, comprising at least one meter module, a bus interface module, and an evaluation and assignment module connected to the bus interface module and to the meter module;

• wherein the meter unit is implemented in hardware;
• and
• wherein the bus interface module enables:
• the meter unit to be coupled to a bus system so that:
• input data for the meter module is received from the bus system, with the evaluation and assignment module being adapted to mask, to extract, and to evaluate the input data for the meter module from a data stream transferred on the bus system, and to assign and forward them to the meter module, and
• result data from the meter module is output onto the bus system.
