Method for transferring data between a position-measuring device and an associated processing unit and position-measuring device therefor

摘要

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.

1. A method for transferring data between a position-measuring device and an associated processing unit, the method comprising:
transferring first data having a first priority in successive cycles from the position-measuring device to the processing unit, the successive cycles being in each case initiated by a request command by the processing unit requesting the first data from the position-measuring device; transferring second data having a second, lower priority from the position-measuring device to the processing unit in at least a portion of the successive cycles with the first data, wherein types of the second data being transferred in a respective one of the successive cycles are variable; assigning at least one particular type, of the types of the second data to be transferred, to individual cycles of the successive cycles using information stored in the position-measuring device without involvement of the processing unit; and defining sequences of the second data, for use in the assigning, in an order defined by at least one transmission list stored in a memory of the position-measuring device.
