Patent number: 9869547Abstract: A position-measuring device includes a position-sensing unit, a processing unit, an interface unit, a clock generator and a time measurement unit position-sensing unit configured to generate digital position values. The processing unit processes instructions from subsequent electronics. The interface unit communicates with the subsequent electronics, according to rules of an interface protocol, via at least one interface line that transmits interface signals having a temporal behavior that is determined by the interface protocol so as to transmit the instructions from the subsequent electronics to the processing unit. The clock generator generates a clock signal that serves as a time base for functions of the position-sensing unit and the processing unit. The time measurement unit uses the clock signal as a time base, receives at least one interface signal and measures a time interval between a start event and a stop event of the at least one interface signal.Type: GrantFiled: September 22, 2014Date of Patent: January 16, 2018Assignee: DR.

Patent number: 9823646Abstract: A method generates an asynchronous trigger signal in a position-measuring device having a position-sensing unit, a processing unit and an interface unit. The position-measuring device is connectable via the interface unit and a bidirectional data channel to subsequent electronics for communication purposes. A synchronous data stream is generated from an asynchronous data stream arriving at the position-measuring device from a direction of the subsequent electronics by sampling the asynchronous data stream in a time pattern of a clock signal. A gate signal is generated upon an enable condition for outputting the trigger signal being detected by evaluating the synchronous data stream. The asynchronous trigger signal is generated upon the gate signal being present and a signal edge of the asynchronous data stream occurring.Type: GrantFiled: June 15, 2015Date of Patent: November 21, 2017Assignee: DR.

Patent number: 9614663Abstract: A method for serial data transmission between a position-measuring device and subsequent electronics over a bidirectional data channel includes transmitting data in data frames and in encoded form in accordance with a data transmission code. The data transmission in each case is initiated by an interface unit at a transmitter end with a start sequence having an encoding scheme that at least partially differs from an encoding scheme of a remainder of the data frames. After a reversal of data direction, an interface unit at a receiver end detects a beginning of the data transmission in each case by detection of the start sequence.Type: GrantFiled: September 17, 2015Date of Patent: April 4, 2017Assignee: DR.

Patent number: 9213499Abstract: A method for transferring data between a position-measuring device and an associated processing unit includes transferring first data having a first priority in successive cycles from the position-measuring device to the processing unit. The successive cycles are in each case initiated by a request command by the processing unit requesting the first data from the position-measuring device. Second data having a second, lower priority is transferred from the position-measuring device to the processing unit in at least a portion of the successive cycles with the first data. Types of the second data being transferred in a respective one of the successive cycles are variable. At least one particular type, of the types of the second data to be transferred, is assigned to individual cycles of the successive cycles using information stored in the position-measuring device without involvement of the processing unit.Type: GrantFiled: May 13, 2014Date of Patent: December 15, 2015Assignee: DR.
