How to realize wireless Ethernet high-speed communication for multiple Mitsubishi PLCs?

Ethernet wireless communication generally has the following application scenarios ：

1.PLC And PLC Wireless communication between

Support point-to-point and point to multipoint , More than one PLC Ethernet wireless communication between

2. Configuration software and PLC Wireless communication between

Kingview 、 Force control 、MCGS Kunlun general state 、Wincc And other mainstream configuration software 1 One or more PLC Wireless communication between

3. Touch screen and PLC Wireless communication between

Human machine interface touch screen and 1 One or more PLC Wireless communication between

In these application scenarios , If you want to successfully realize wireless Ethernet communication between devices, you need to use Ethernet communication terminal , For example, the Japanese system PLC Wireless communication terminal DTD419M . It can not only communicate with PLC、DCS、 The wireless measurement and control system is composed of intelligent instruments, sensors and other equipment , At the same time, it can communicate with configuration software 、 The man-machine interface 、 Touch screen 、 Industrial control products such as measurement and control terminals realize point-to-point （ PTP） And point to multipoint （ PTMP ） Remote wireless networking , Connect scattered equipment that is not convenient for trenching and wiring , There's no need to program , No wiring required , And stable and reliable .

also ,DTD419M use 2x2 Two transmitter and two receiver wireless architecture , The air transmission rate is as high as 300Mbps, Compatible with MITSUBISHI MELSOFT Connect 、MC、BCNetTCP、Scoket、Modbus TCP Wait for the communication protocol , And USES the OFDM Modulation and MINO technology , Make the wireless reliable transmission distance reach 1KM Can be used in any range .

Let's take Mitsubishi FX5U PLC Take Ethernet communication between as an example , Explain to you how to use Ethernet module to realize PLC Inter distance Modbus tcp High speed communication .

Mitsubishi FX5U PLC Ethernet communication between , In fact, it is a simple PLC Inter link function , At most 8 platform FX5u Programmable controller or FX3u Between programmable controllers , The function of interlinking soft components . In a real system , Multiple machines are distributed in the same workshop PLC, The distance usually ranges from tens of meters to hundreds of meters . When there is communication demand , If you have wiring , Large quantities and unsightly , In this case, wireless communication is more suitable .

With Mitsubishi FX5u-32MRPLC For example , On two FX5u-32MRPLC Ethernet wireless communication under simple Ethernet connection , Japanese system is adopted in this process PLC Wireless communication terminal DTD419M, As a hardware device to realize wireless communication . There is no need to change the network parameters and the original program , You don't have to know the details of the agreement , Through the Datai Japanese system PLC Dedicated wireless communication terminal --DTD419M, You can directly replace PLC Wired Ethernet communication between , And stable and convenient wireless communication .

1. Wiring way

Use a communication line , One end is connected to DTD419M Of RJ45 Interface , The other end is connected to FX5u Of RJ45 Interface .
