Method for data communication

In a method for data communication between a control unit and a drive system, the control unit and the drive system are connected to one another, preferably via a bus, in such a manner that data is transmitted by a telegram. The telegram includes an instruction which can be configured for recording and includes an identifier. At least one actual value, preferably a plurality of actual values, and/or of an actual value sequence, preferably a plurality of actual value sequences, of the drive system, are recorded through the instruction for recording, and at least one defined actual value from a plurality of actual values and/or recording at least one defined actual value sequence from a plurality of actual value sequences can be recorded through the identifier.
