Embodiment Construction

[0073] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0074] The invention provides an automatic generation method of a Modbus slave station simulator system to solve the problem that a computer RS232 interface cooperates with a simulation software to simulate a Modbus slave station device to communicate with a Modbus master station. The communication method when not using the Modbus simulator system is as follows: figure 1 As shown, the Modbus master communicates with the Modbus slave device through the RS232 interface or the RS485 interface. The communication method after using the Modbus simulator system is as follows: figure 2 As shown, the Modbus master station communicates with the Modbus slave station simulator system composed of computer software and the RS232 interface of the computer.

[0075] The task of the present invention is to provide an automatic generation method of a Modbus slave station si...

Abstract

The invention provides an automatic generation method for a Modbus slave-station simulator system. The slave-station simulator system is customized from the aspects including external behavior description, Modbus slave-station information description and external characteristic description. The slave-station simulator system possess excellent equipment similarity, which can substitute equipment for consistency and interoperability tests before and after production. The method can not only customize operation program of the slave-station simulator system but also generate source codes, wherein the source codes can be directly applied to development of a protocol device. The automatic generation method of the invention can reduce the complexity of protocol engineering, and has great significance in automation of the protocol engineering.

Description

technical field [0001] The invention belongs to the technical field of communication protocol automation, in particular to an automatic generation method of a Modbus slave station simulator system. Background technique [0002] Modbus protocol is a general protocol applied to electronic controllers. Modbus can support a variety of electrical interfaces, such as RS232, RS485, etc., and can also be transmitted on various media, such as twisted pair, optical fiber, wireless, etc.; the frame format of Modbus is simple, compact, easy to understand, easy for users to use, manufacturers Simple to develop, it has become a popular industry standard among users. [0003] With the development of industrial automation technology, the number of industrial communication devices (referred to as devices) that meet the Modbus protocol is increasing. In order to enable various communication devices to realize interconnection and interoperability, higher requirements are put forward for prot...
