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 () which has at least one associated clock generator () and a memory unit () and which is connected at least to a data source (), 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 (), with these programs being associated with the microcontroller (). The first and the second program can be run alternately.

An automation device is disclosed, in which a multiplicity of physically distributed functional units communicate with each other by means of a common transmission protocol. The device has a microcontroller (), which has a group of associated input/output connections which are connected to a resistor network. The resistances of the resistors follow a sequence, the resistance respectively being doubled from the less significant to the next most significant bit. Each input/output connection is actively switched to the associated logic level in order to output a first logic state and is connected as a high-impedance input in order to output the inverse, second logic state.
