Abstract:
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.
