1. A method for determining proximity relationships between an actuator and sensors which interact with the actuator in an installation for controlling a technical process and which communicate with the actuator, the actuator influencing the process and the sensors capturing measured values of process variables, the method comprising:
influencing, by the actuator, the technical process in accordance with a predefined test pattern;
searching, by the actuator, for the predefined test pattern in sequences of measured values received from the sensors as responses to the test pattern; and
identifying, by the actuator, a sensor whose response best satisfies a predefined quality criterion in terms of response quality and response time as the sensor with a greatest operative proximity to the actuator;
wherein the response quality contains a degree of a correlation between the test pattern and the response.
