Abstract: A system for automated treatment of fluids having interchangeable process modules (39, 40, 41, 42, 43), which are arranged next to each other, and which are respectively provided with a control unit and a fluid unit. The fluid unit is controlled by the control unit in order to carry out a module-specific process function during the treatment of the fluids. The control units are interconnected via a data bus (48), which is common to the process modules (39, 40, 41, 42, 43), and the fluid units are interconnected by a fluid bus (49) that has several channels. A fluid bus section is provided for at least one part of the channels inside each process module (e.g., 42). This section has fluid bus interfaces (52) at the ends thereof. A connection unit (51) is configured to be mounted between the respectively adjacent fluid bus interfaces (52) of two successive process modules (e.g., 41, 42) in at least two different mounting positions.
