METHOD FOR CREATING AN ASSIGNMENT FILE OF A COMMUNICATION PROTOCOL

摘要

In order to be able to determine an assignment file for a communication protocol of a data bus of a machine in a simple manner, provision is made for a predefined sequence of actions to be carried out on the machine (2), which sequence of actions generates at least one sought data signal (DS) in a bus message (N) on the data bus (1), and for the bus messages (N) transmitted via the data bus (1) during the sequence of actions to be recorded, wherein at least some of the data fields (D) of the recorded bus messages (N) are evaluated by means of a heuristic method which establishes a relationship between the sequence of actions and the data signal (DS), from which a possible bus message (N) containing a message identifier (ID) and a possible bit position (P) and length (L) of the data signal (DS) in the bus message (N) are determined for the sought data signal (DS), and for the message identifier (ID) of the bus message (N) and the bit position (P) and length (L) of the data signal (DS) in the bus message (N) to be entered in the assignment file (5).
