威纶通MT6071IP和fx5u怎么用485通讯？
详细说说硬件连接和软件设置
推荐回答（2个）
FX5U是走网络通讯更加便利，需要选择带网口的触摸屏，如MT8071IP。
用内置的485也可以，
1.设置PLC为：MC--9.6k—E—7--1—和
2设置触摸屏为：PLC选择FX5U，COM设置485 2w， com1， 9600 E7 1
3接线：data-连接SDB.RDB
data+连接SDA.RDA
SG连接SG
按照这上面的也可以链接，威纶通精展达高工回复，希望您采纳
本方案中，无需更改网络参数和原有程序，通过PLC专用无线通讯终端DTD419MB，即可直接替换触摸屏与PLC之间有线以太网通讯，且稳定方便的实现EtherNet/IP协议下无线以太网通讯。

▼二、测试设备与参数
● 三菱PLC型号：FX5u × 2台
● 触摸屏：威纶通TK8071IP × 1台
● PLC无线通讯终端——DTD419MB × 3块
● 主从关系：1主2从
● 通讯接口：RJ45接口
● 供电：12-24VDC
● 通讯协议：EtherNet/IP协议
● 传输距离：100米，1KM
三、PLC无线通讯终端--DTD419M
达泰DTD419M采用 2x2 两发两收无线架构，空中传输速率高达 300Mbps，兼容三菱MELSOFT连接、MC、BCNetTCP、Scoket、Modbus TCP等通讯协议，并采用 OFDM 调制及 MINO 技术，使无线可靠传输距离达到1KM范围内均可使用。
DTD419M 不仅能与 PLC、DCS、智能仪表及传感器等设备组成无线测控系统，同时能与组态软件、人机界面、触摸屏、测控终端等工控产品实现点对点和点对多点的远程无线组网，将分散不便于挖沟布线的设备连接在一起，不需要编写程序，不需要布线，并且稳定可靠。
■ 主 要 特 征:
◆ 可以直接代替有线以太网线，实现无线组网；
◆ 支持三菱MELSOFT连接、MC、BCNetTCP、Scoket、Modbus TCP等通讯协议；
◆ 全数字无线加密传输方式，不插卡无运行费用；
◆ 无需更改程序，即插即用，自适应接口协议；
四、接线方式
1、触摸屏与DTD419MB接线：
用一根通讯线，一端接入DTD419MB的RJ45接口，另一端接入触摸屏的RJ45接口。
2、PLC与DTD419M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。
五、触摸屏配置
1.系统参数设置
2.触摸屏画面的制作
3.参数的对应
4.运行说明六、PLC的简单配置
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
七、测试方法
1、用触摸屏的启动/关闭按钮控制PLC对应的Y点，同时在触摸屏上监测Y点输出。
2、给PLC的X点输入信号，看触摸屏是否有监测到相应点的信号。
