Abstract

The invention discloses a data communication method based on a single-side point table. The method comprises the following steps: S1, constructing a communication point table of a slave station at the slave station; s2, after communication connection is established between the master station and the slave station, calling the content of the communication point table of the slave station to the master station; s3, after the master station receives the content of the communication point table of the slave station, a communication point table, consistent with the communication point table of the slave station, of the master station is established after checking; according to the method, the problem of errors caused by inconsistency of point tables defined by two communication parties respectively is solved.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a data communication method based on a one-sided point table. Background technique [0002] The IEC101 / 104 protocol is a communication protocol mainly used in the control and information collection of power systems, urban rail transit and other industries, formulated by the International Electrotechnical Commission. The IEC101 / 104 protocol uses an application service data unit (ASDU) for data transmission, and the application service data unit (ASDU) includes an address field, which is used to indicate which information data is transmitted. The data type of the address field is an integer value type. Before data exchange, both parties of data communication need to load the pre-defined communication point table respectively. The communication point table contains an ordered set of data points that need to be interacted with. Each data point is assigned a unique information addre...
