Demo演示(C、C++):
ModbusRTU模式使用示例 1. 项目介绍
本项目演示如何配置RS485端口为ModbusRTU模式,并通过接口与连接的外设进行读写操作,示例操作流程如下:
完成配置通讯端口ModbusRTU模式、写单圈数据、读单圈数据、写单个寄存器、读保存寄存器、关闭通讯端口 Modbus RTU 模式。
项目基于Cmake构建,使用了睿尔曼提供的机械臂C语言开发包。

4. 环境配置
在Windows和Linux环境下运行时需要的环境和依赖项:
项目 | Linux | Windows |
---|---|---|
系统架构 | x86架构 | - |
编译器 | GCC 7.5或更高版本 | MSVC2015或更高版本 64bit |
CMake版本 | 3.10或更高版本 | 3.10或更高版本 |
特定依赖 | RMAPI Linux版本库(位于Robotic_Arm/lib 目录) | RMAPI Windows版本库(位于Robotic_Arm/lib 目录) |
Linux环境配置
1. 编译器(GCC) 在大多数Linux发行版中,GCC是默认安装的,但可能版本不是最新的。如果需要安装特定版本的GCC(如7.5或更高版本),可以使用包管理器进行安装。以Ubuntu为例,可以使用以下命令安装或更新GCC:
# 检查GCC版本
gcc --version
sudo apt update
sudo apt install gcc-7 g++-7
注意:如果系统默认安装的GCC版本已满足或高于要求,则无需进行额外安装。
2. CMake CMake在大多数Linux发行版中也可以通过包管理器安装。以Ubuntu为例:
sudo apt update
sudo apt install cmake
# 检查CMake版本
cmake --version
Windows环境配置
1. 编译器(MSVC2015或更高版本) MSVC(Microsoft Visual C++)编译器通常随Visual Studio一起安装。可以按照以下步骤安装:
- 访问Visual Studio官网下载并安装Visual Studio。
- 在安装过程中,选择“使用C++的桌面开发”工作负载,这将包括MSVC编译器。
- 根据需要选择其他组件,如CMake(如果尚未安装)。
- 完成安装后,打开Visual Studio命令提示符(可在开始菜单中找到),输入
cl
命令检查MSVC编译器是否安装成功。
2. CMake 如果Visual Studio安装过程中未包含CMake,可以单独下载并安装CMake。
- 访问CMake官网下载适用于Windows的安装程序。
- 运行安装程序,按照提示进行安装。
- 安装完成后,将CMake的bin目录添加到系统的PATH环境变量中(通常在安装过程中会询问是否添加)。
- 打开命令提示符或PowerShell,输入
cmake --version
检查CMake是否安装成功。
5. 使用指南
5.1 快速运行
按照以下步骤快速运行代码:
配置机械臂IP地址: 打开
main.c
文件,在main
函数中修改robot_ip_address
参数为当前机械臂的IP地址,默认IP地址为"192.168.1.18"
。Cconst char *robot_ip_address = "192.168.1.18"; int robot_port = 8080; rm_robot_handle *robot_handle = rm_create_robot_arm(robot_ip_address, robot_port);
linux 命令行运行: 在终端进入
RMDemo_ModbusRTU
目录,输入以下命令运行C程序:bashchmod +x run.sh ./run.sh
运行结果如下:
参考 Windows 的运行结果。
Windows 运行: 双击run.bat脚本运行 运行结果如下:

获取API版本
Cchar *api_version = rm_api_version(); printf("API Version: %s.\n", api_version);
获取并显示API版本。
配置Modbus RTU模式
Crm_set_modbus_mode(robot_handle, 0, 115200, 10);
写单圈数据
Crm_peripheral_read_write_params_t write_params = {0, 0, 2, 1}; result = rm_write_single_coil(robot_handle, write_params, 1);
读单圈数据
Crm_peripheral_read_write_params_t read_params = {0, 0, 2, 1}; int coil_data; result = rm_read_coils(robot_handle, read_params, &coil_data);

Crm_peripheral_read_write_params_t write_single_register_params = { 0, 0, 2, 1}; result = rm_write_single_register(robot_handle, write_single_register_params, 180); if (check_result(result, "Failed to write single register") != 0) { return -1; }
读保存寄存器
Crm_peripheral_read_write_params_t holding_registers_params = {0, 0, 2, 1}; int holding_register_data; result = rm_read_holding_registers(robot_handle, holding_registers_params, &holding_register_data);
