Abstract
A method for checking an installation location of a component in a failsafe automation system, wherein the components are connected to one another in series and uniquely defined addresses are continuously assigned from a first component to successor components, wherein, after the assignment of addresses to the components, a switching device is operated in the components such that a signal transit time measurement is performed incrementally with a test signal for each successor component, and wherein the test signal is emitted and re-received and the installation location of the successor component is check based on the time difference.

A method for checking an installation location of a component in a failsafe automation system, comprising the steps of:
- connecting a plurality of components to one another in series;
- assigning, continuously, uniquely defined addresses from a first component of the plurality of components to successor components of the plurality of components;
- and
- operating a switching device of each of the successor components after the assignment of the addresses to the successor components such that a signal transit time measurement is performed incrementally with a test signal for each successor component, the test signal being emitted and re-received and an installation location of each of the successor components being checked based on the time difference.
An automation component configured to operate in a safety-oriented automation system, and further configured to check an installation location in a failsafe automation system, and configured to connect to further components in series, the automation component comprising:
- a transit time delay element;
- a microprocessor;
- and
- a switching device which connects the transit time delay element into a signal path between a predecessor component and a successor component for a signal transit time measurement, such that a test signal is emitted via the microprocessor and is re-received;
- wherein the microprocessor is configured to check the installation location based on a time difference between emission and reception of the test signal.
