Claim:
1. An automation device, for connection to a second automation device via a single communication line, the automation device comprising: a data sink, a data source, a microcontroller with a least one associated clock generator and a memory unit, the microcontroller having a first associated program for conversion of a first data byte stream, which is received from the data source, to a sequence of sample values of a first frequency-modulated line signal, which is subsequently transmitted to the second automation device via the communication line, and the first program is stored in the memory unit, the microcontroller further having a second associated program for identification of a second frequency modulated line signal, which is received from the second automation device via the communication line, and for its sequential conversion to a second data byte stream, which is subsequently transmitted to the data sink, and the second program is stored in the memory unit, and the first and the second programs are run alternately.
