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, having a microcontroller, which is assigned at least one clock generator and one memory unit, and which is connected at least to one data sink, which is designed to accept a received data bit-stream,

characterized in that

to reconstruct the received data bit-stream, provision is made of a cascade circuit comprising a monoflop (181), a sampling device (182), a low-pass filter (183) and a comparator (184).
