If, for example, measuring devices with different communication modes are used, corresponding evaluation devices with different communication modes must also be used in order to be able to provide communication between these devices. However, this necessity increases the costs and also reduces the flexible use of the various devices in a system. These disadvantages are avoided or at least reduced by the present invention.
