Abstract

The invention relates to an automation device, with which a multiplicity of physically distributed functional units communicate with each other by means of a common transmission protocol. The device has a microcontroller (110), which is assigned at least one clock generator (120) and one memory unit (150), and which is connected at least to one data source (140), which is designed to output a data bit-stream to be transmitted.

Claims

1. An automation device, with which a multiplicity of physically distributed functional units communicate with each other by means of a common transmission protocol, the automation device comprising:

a microcontroller, which is assigned at least one clock generator and one memory unit, and which is connected at least to one data source, which is designed to output a data bit-stream to be transmitted, wherein a first table includes a sequential sequence of equidistant samples having a first frequency and a second table includes a sequential sequence of equidistant samples at a second frequency, said first and said second tables being stored in the memory unit (150), such that said first table or said second table can be called up, in such a manner that, depending on the data bit-stream, the samples can be alternately output from the first table (151) to output a logic one or from the second table (152) to output a logic zero, using the same said at least one clock generator; and

wherein each table (151, 152) is divided into n areas, the respective first samples each being phase-shifted through 2*π

/n.

2. The automation device of claim 1, wherein the microcontroller is connected to a data source and a data sink.

3. The automation device of claim 2, wherein the data source comprises a configurable sensor for converting a physical variable into an electrical variable, and wherein the data sink comprises a configuration of the sensor.

4. The automation device of claim 2, wherein the data sink comprises an actuator for converting an electrical variable into a physical variable whose properties can be diagnosed, and wherein the data source comprises a diagnostic device for diagnosing the physical variable.
