Abstract

The invention relates to an automation device, in which a plurality of spatially distributed functional units communicate with one another by means of a common transmission protocol. The device has a microcontroller (110) which has at least one associated clock generator (120) and a memory unit (150) and which is connected at least to a data source (140), which is designed to output a data byte stream to be transmitted. A first program for conversion of a data byte stream to be transmitted to a sequence of sample values of an adequate frequency-modulated line signal, and a second program for identification of a frequency-modulated line signal and for its sequential conversion to a received data byte stream are stored in the memory unit (150), with these programs being associated with the microcontroller (110). The first and the second program can be run alternately.
