System for automated treatment of fluids having successive and interchangeable process modules

A system for automatically treating fluids, comprising:

• a plurality of interchangeable, successive process modules, each process module comprising:
• a control unit;
• and
• a fluid unit controlled by the control unit, wherein the fluid unit is configured to carry out a module-specific process function in the course of automatically treating the fluids;
• a data bus, which is common to the process modules and which interconnects the respective control units of each process module;
• a fluid bus comprising a plurality of channels, which interconnects the respective fluid units of each process module, wherein a predefined number of the channels comprises respective fluid bus sections within the process modules, and wherein the respective fluid bus sections have fluid bus interfaces at the ends of the respective fluid bus sections;
• and
• a connection unit mounted between adjacent ones of the fluid bus interfaces of two successive ones of the process modules, wherein the connection unit is configured to be mounted in at least two different mounting positions, in accordance with which the connection unit is configured to connect channel sections terminating at the adjacent ones of the fluid bus interfaces in respective, differing connection patterns.
