Abstract

A method for reading a serial data stream in a piece of automation technology equipment includes encoding the data stream to include at least two symbols which are distinguishable by a time interval between two successive signal edges. The data stream is delivered to a read unit including a symbol recognition unit which associates a time sequence of the signal edges with a respective one of the symbols taking into account a period of time including a current symbol duration of one of the symbols to be currently associated and at least one old symbol duration of a preceding one of the symbols.
