Abstract
In a device and a method for the automated detection of an interface between a position-measuring device and sequential electronics that are interconnected via a data-transmission channel, the position-measuring device includes an interface unit and a position-measuring unit. The interface unit is connected first of all to the data-transmission channel, and secondly to the position-measuring unit for the purpose of an internal data exchange. The interface to the sequential electronics is selectable in the interface unit from at least two interfaces. Also disposed in the position-measuring device is an interface-detection unit, which is supplied with at least one input signal that arrives from the sequential electronics via the data-transmission channel, and which includes a device for determining the time sequence of signal edges of the at least one input signal in conjunction with the signal status, as well as an evaluation unit in which the interface used to the sequential electronics is detectable by evaluating the time sequence determined, and is selectable in the interface unit.
