Device and Method for Transmitting Data Between a Position-Measuring Device and Sequential Electronics

A system, comprising:

• a position-measuring device;
• sequential electronics;
• and
• a data-transmission channel;
• wherein the position-measuring device includes an interface unit and a processing unit, the interface unit connected to the data-transmission channel and to the processing unit for an internal data exchange by a request channel and a response channel, the interface unit including a command interpreter adapted to convert, in accordance with conversion rules, commands that arrive via the data-transmission channel into internal requests and to feed via the request channel to the processing unit, the interface unit adapted to convert response data that arrives from the processing unit via the response channel into output data, the interface unit including a rules memory adapted to store the conversion rules, the rules memory being at least partially modifiable.

A method for transmitting data between a position-measuring device and sequential electronics via a data-transmission channel, the position-measuring device including an interface unit and a processing unit, the interface unit connected to the data-transmission channel and to the processing unit for internal data exchange by a request channel and a response channel, comprising:

• storing conversional rules in a rules memory of the interface unit, the rule memory being at least partially modifiable;
• converting, by a command interpreter of the interface unit, in accordance with conversion rules, commands that arrive via the data-transmission channel into internal requests;
• feeding the internal requests via the request channel to the processing unit;
• converting response data that arrives from the processing unit via the response channel into output data;
• and
• transmitting the output data to the sequential electronics.
