Dynamic analysis method, device, server and storage medium based on modbus protocol

Abstract

The invention discloses a dynamic parsing method, equipment, server and storage medium based on the modbus protocol. The method includes: acquiring original modbus data uploaded by the equipment; searching for a protocol mapping table corresponding to the equipment according to the original modbus data; Obtaining the function code in the original modbus data, and adopting the function code instruction corresponding to the function code to parse the original modbus data; performing the modbus address obtained by parsing with the pre-configured modbus address in the protocol mapping table Matching; when there is a pre-configured modbus address corresponding to the modbus address obtained by parsing in the protocol mapping table, assign the address value obtained by parsing to the code corresponding to the pre-configured modbus address for the upper layer The value is obtained through the encoding. Based on the invention, the flexible analysis of the protocol at the server end can be realized, and the development workload is reduced.

Description

technical field [0001] The invention relates to the modbus field, in particular to a dynamic analysis method, device, server and storage medium based on the modbus protocol. Background technique [0002] Modbus is the world's first real bus protocol for industrial field formulated by Modicon (now a brand of Schneider Electric Company) in 1979. The modbus protocol has now become a common industrial standard, which is widely used in the communication interconnection between controllers. When communicating on a modbus network, each controller needs to know the device addresses of all controllers communicating with it in the network, identify the messages sent by the addresses, and decide what action to take. If a response is required, the controller will generate a feedback message and send it using the modbus protocol. [0003] As the pace of the intelligent era accelerates, it becomes necessary to connect traditional modbus devices to the cloud. Although modbus is a standa...

Problems solved by technology

Although modbus is a standard protocol, due to its good scalability, each product of each manufacturer may have different content in the protocol. Therefore, when analyzing in the cloud, it is necessary to analyze multiple sets of protocols according to different contents. , each new product requires a certain amount of development tasks, which increases the difficulty and cost of development
