Abstract
The invention relates to the field of modular analytical systems. The invention enables the topology of a modular analytical system to be determined without requiring additional complicated measures such as a system reset. The method/system is also adapted to industry standards such that CAN-busses can be used.

17. A method for determining the topology of modules in a modular analytical system comprising:
-
a) contacting several modules which store data in a memory with a central unit, wherein at least two modules are connected in series, b) transmitting the stored data of the modules that are directly or indirectly contacted with the central unit to the central unit, c) interrupting a contact of a module to the central unit, d) transmitting the stored data of the modules to the central unit, e) restoring the interrupted contact, and f) comparing the data that were transmitted before the contact was interrupted with the data that were transmitted after interruption of the contact and determining the topology of the modular analytical system on the basis of the comparison, wherein the method steps c to e are repeated with at least one other module until sufficient information is available from the comparison to calculate the topology. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

25. A modular analytical system comprising:
-
a central unit which is contacted with several modules, wherein at least two of the modules are connected in series and the modules each comprise a memory to store data, a switch which can be controlled by a computer unit in such a manner that the contact of a module to the central unit can be interrupted and restored again, wherein the computer unit comprises a control unit to control the switch, a memory to register the data of the modules, and a computing unit to calculate the topology of the analytical system on the basis of a comparison of data that were registered before interrupting a contact between the central unit and a module with data that were registered after interruption of the contact. - View Dependent Claims (26, 27, 28, 29, 30, 31)
