组态软件与西门子S7系列PLC及三菱PLC间的无线通信测试需要用到以下设备：
l 西门子PLC型号：S7-200Smart × 2台
l 三菱PLC型号：FX5U × 2台
l 上位机：力控V7.1 × 1台
l 无线通讯终端（网口版）——DTD418MB × 3块
l 无线通讯终端（网口版）——DTD419MB × 2块
l 主从关系：1主4从
l 通讯接口：RJ45接口
l 供电：12-24VDC
本方案中，用户无需更改网络参数和原有程序，也不必了解协议细节，通过无线通讯终端，即可直接替换力控与PLC之间有线以太网通讯，且稳定方便的实现PLC无线以太网通讯。
无线网络图如下：
接线方式：
1. 上位机与DTD418MB接线
用一根通讯线，一端接入DTD418M的RJ45接口，另一端接入上位机的RJ45接口。
2. PLC与DTD418MB接线
用一根通讯线，一端接入DTD418M的RJ45接口，另一端接入S7-200SMART的RJ45接口。
3. 三菱FX5U与DTD419MB接线
用一根通讯线，一端接入DTD419MB的RJ45接口，另一端接入FX5u的RJ45接口。
力控组态参数设置及测试界面：
1.打开相关文件夹
把该例程拷贝到力控软件工程目录下。
如下图目录所示路径，搜索项目，启动开发
2.组态测试界面
3. 西门子PLC IO设备组态
选择 S7-200 TCP协议。设备配置按如下步骤进行。
4. 数据库组态
分别为两台200SMART进行变量组态
5. 三菱PLC IO设备组态
选择“A、ANA系列以太网”，设备配置按如下步骤进行。
6. 数据库组态
分别为两台FX5U进行变量组态
西门子PLC参数设置：
1. IP地址的更改
2. CPU模式选择：RUN
3. 200SMART的程序
三菱PLC参数设置：
1. 新建工程，并如下图所示
2. 选择SLMP连接设备左键拖动到下面
设置协议 端口号。要和触摸屏一致。
3. 简单程序的编写
用M点驱动相应的Y点输出
4. 下载程序到CPU
2台PLC的IP分别设置192.168.2.14和192.168.2.15。将程序下载到PLC
测试方法：
1、由200SMART的I0.0和I0.1的输入开关可以确认通信是否正常。
2、用鼠标点击M点按钮,左键打开，右键关闭，看对应的Q点是否输出。
3、由FX5U的X0和X1的输入开关可以确认通信是否正常。
4、用鼠标点击M点按钮,左键打开，右键关闭，看对应的Y点是否输出
