基于Modbus仪表的通用测试软件的设计

The Design of Test Sofeware for the Modbus-based Intelligent Instrument

为了方便基于Modbus的多功能智能仪表的测试功作，提高测试效率，研究了应用简单的图形界面，自动组织报文、发送报文、解释报文的功能。根据通用的Modbus通信标准，提出更为高效的测试软件设计方法，再应用c#软件进行具体实现，使测试软件可以通过界面点击实现智能仪表的测控，并自动通过后台发送测试报文实时更新显示所需的各台智能仪表的数据量。通过实验显示所提的测试软件具有简单友好的用户界面，且功能完善，能高效实现测试任务。

To simplify the Modbus-based multi-functional intelligent instrument testing, improve test efficiency, the graphical interface and a series of Function is designed, like automatically organizing messages, sending messages and explaining the function of the message. According to Modbus standard, more efficient test software design methods is proposed, and then c # is used for programming the soft- ware. Clicking graphical interface, it can test the corresponding intelligent instruments, automatically send test packets, real-time update and display some of the intelligent instrument data. Experiments show that the software proposed has a simple user-friendly interface, is functional and can efficiently achieve the test tasks.
