摘要：

In this paper is presented a communication protocol designed to the data transfer among the automation systems which include programmable controllers. By introducing an additional bit to identify an address or data byte, reduce the volume of data to be processed by the MCUs slave. Decreasing the slave station interrogation cycle period, for faster update of parameters, is realized by minimizing the number of transmitted characters depending on the data type. To eliminate errors due to distortions each character is sent asynchronously.
