本课程名为“如何读取Modbus RS485温度传感器的**数据”，旨在帮助学生掌握从Modbus RS485设备读取数据的完整流程。 课程内容基于学生**的实际需求，以一个具体的温湿度传感器为例，**示了如何将一个Modbus RS485设备“开箱即用”地连接到Modbus网络，并读取和显示其数据**。 **主要步骤包括：** 1. **设备分析**：深入分析温湿度传感器的相关文档，**确其Modbus通信参数。 2. **网络连接**：通过USB-to-RS485转换器将设备连接到**电脑。 3. **软件配置**：使用Modbus主控测试软件，根据设备文档**确寄存器地址。 4. **HMI应用开发**：利用Winlog Lite这款免费软件，创建用户友好的**人机界面（HMI）应用程序。 5. **数据读取与显示**：通过HMI应用程序读取Modbus设备的数据，并以直观的方式展示。 课程强调**实践性，以系统、逻辑**的方式指导学生完成每一步。**课程提供的所有软件工具均为免费试用版，学生可以下载并进行实践。
This course as created as a result of requests of students who wanted to have a single example of a Modbus-enabled RS485 device being taken "out of the box" and the steps taken to connect the device onto a Modbus RS485 network where it's data values could be read and displayed.The course uses a Temperature / Humidity sensor that has Modbus RS485 capability, as the device to be connected to the Modbus network. The documentation associated with the device is analyzed and is then used to configure Modbus master test software, where register addresses are confirmed.The device is connected to a PC via a USB-to-RS485 converter. After verification of data register addresses, a Human Machine Interface (HMI) application is created using an application called Winlog Lite. The HMI application is then used to read the data values from the Modbus device and display those values in a user-friendly format.The course is extremely practical and steps he student through the complete process in a very systematic and logical manner. As the software tools are all free trials, the student will be able to download the applications and practice further.
