DEVICE AND METHOD FOR THE DATA TRANSFER BETWEEN A POSITION MEASUREMENT DEVICE AND SUBSEQUENT ELECTRONICS

摘要

In a device and a method for transmitting data between a position-measuring device and sequential electronics via a data-transmission channel, the position-measuring device includes an interface unit and a processing unit, the interface unit being connected first of all to the data-transmission channel, and secondly, to the processing unit for the purpose of an internal data exchange with the aid of a request channel and a response channel. The interface unit includes a command interpreter by which, using conversion rules, commands which arrive via the data-transmission channel are convertible into internal requests and are able to be fed via the request channel to the processing unit, and response data which arrives from the processing unit via the response channel is convertible into output data. The interface unit further includes a rules memory for storing the conversion rules, which is at least partially modifiable.
