Read-write operation implementation method and device based on dynamic protocol point table

Abstract

The invention discloses a read-write operation implementation method and device based on a dynamic protocol point table. The method comprises the steps of analyzing a to-be-processed protocol under the condition that the to-be-processed protocol is received, and obtaining a point location address and a read-write demand type of the to-be-processed protocol; receiving a configuration file issued by an upper computer; point location information matched with the point location address is inquired according to the configuration file, so that a point location mapping table for processing the protocol to be processed is obtained, and the point location mapping table is a mapping table obtained by combining the point location address and the point location information matched with the point location address; and executing read / write operation according to the point location mapping table according to the read / write demand type. According to the method and the device, the technical problems that in related technologies, the Modbus protocol point table is generally fixed, so that resource and time waste is easily caused, a program is generally required to be modified when the Modbus protocol point table is changed, the process is complex, and the cost is relatively high are solved.
