Abstract

In a method for testing the ground contact of parts of a networked system in which data are sent and received via at least one line, at least one line at each part is connected via a resistance arrangement to a common potential of the parts and is connectable via a controllable switch to a further potential. The voltage across the resistance arrangement is compared with a predetermined potential when the line is at one potential in a steady state, and the state of the ground contact of the part is deduced from a comparison of the voltage across the resistance arrangement with the predetermined potential.
