Problems solved by technology

Since only function codes 01, 02, 03, 04, 05, and 06 can be tested in the relevant technical solutions, other function codes that are different from the six types of function codes cannot perform test interaction, and because the software The server ModSim lacks restrictions on the value range, so it cannot receive response m

Abstract

The invention provides a testing method and device. The testing method comprises the steps of sending a first detection message for a safety protection function based on a Modbus protocol; and reconstructing and sending a second detection message according to the response condition of the response message corresponding to the first detection message and the attribute information of the first detection message. According to the technical scheme, the packet sending strategy can be automatically adjusted, and the manual operation link in the test process is simplified.

Description

technical field [0001] The present application relates to the field of network technology, in particular to a testing method and device. Background technique [0002] With the development of network technology, data interaction and communication based on the Internet protocol makes the equipment in the field of industrial control more and more close. Among them, the Modbus / TCP protocol is the application layer message of the seventh layer of the OSI model. Transmission protocols, which can be applied to different types of buses and networks, have been widely used in industrial communication scenarios. Since the Modbus protocol itself has no security mechanism, there are often risks caused by human misoperation or attack message intrusion in the actual use process. [0003] In order to realize the monitoring of the Modbus protocol safety protection function on the basis of controlling the test cost, in the prior art about the testing process of the Modbus protection function...
