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

Abstract

The present invention discloses a dynamic analysis method and device based on a modbus protocol, a server and a storage medium. The method comprises the steps of: obtaining original modbus data uploaded by a device; searching a protocol mapping table corresponding to the device according to the original modbus data; obtaining function codes in the original modbus data, and employing a function code command corresponding to the function codes to analyze the original modbus data; matching the modbus address obtained through analysis with a pre-configured modbus address in the protocol mapping table; and when the protocol mapping table has the pre-configured modbus address corresponding to the modbus address obtained through analysis, assigning the address value obtained through analysis to the codes corresponding to the pre-configured modbus address to allow an upper-layer terminal to perform value obtaining through the codes. Based on the invention, the dynamic analysis method and device based on the modbus protocol, the server and the storage medium can achieve flexible analysis for the protocol at the server to reduce the development workload.

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
