ABSTRACT:
A method for data communication of bus users of an open automation system such that any bus user with an individual and interactive communication may be connected provides for a communication controller (KC) made up of at least one freely-programmable communication-ALU (RPA, TPA, PEA), with several commands being encoded on a command code for the communication-ALU optimized for particular communication functions, and logic function blocks (FI, Z, V, CRC) are arranged in parallel in the communication ALU (RPA, TPA), which carry out particular communication functions, the communication functions not being definitively defined but rather being formed on the basis of the freely-programmable and communication function optimized communication ALUs (RPA, TPA, PEA), wherein several commands are carried out in a system cycle and transitions between various networks can be carried out.
