Serial data transmission method for position measuring system has actual position measuring data transmitted ahead of further non-time critical data

摘要

The serial data transmission method has position data and further data provided by the position measuring system (10) transmitted to a processing unit (20) in serial format as digital data words, with transmission of actual position measuring data (POSDAT,POSDAT') by the position measuring system in response to a position request command (POSRQ,POSRQ') from the processing unit, before transmission of further data (DAT,DAT') which is not time critical. An independent claim for a serial data transmission device for a position measuring system is also included.
