In this paper, Siemens S7-200SMART For example , Introduce two S7-200Smart PLC Wireless Profinet Communication implementation process . There is no need to change the network parameters and the original program , You don't have to understand Profinet Details of the agreement , Only Siemens PLC Wireless communication terminal DTD418M As a hardware device to realize wireless communication , You can directly replace PLC Wired Ethernet communication between , And realize wireless communication stably and conveniently Profinet The Internet .

DTD418M use 2x2 Two transmitter and two receiver wireless architecture , The air transmission rate is as high as 300Mbps, Compatible with Siemens S7 agreement 、Profinet agreement 、Modbus TCP/IP Wait for the communication protocol , And USES the OFDM Modulation and MINO technology , Make the wireless reliable transmission distance reach 1KM about . Not only 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 and point-to-multipoint remote wireless networking .

The wireless communication scheme is shown below :

The test equipment and parameters are as follows :

● Siemens PLC model :S7-200Smart × 2 platform

● Datai European and American Department PLC Wireless communication terminal ——DTD418MA × 2 block

● Master-slave relationship :1 Lord 1 from

● communication interface :RJ45 Interface

● Power supply :12-24VDC

● transmission distance :100 rice ,1KM

The wiring is as follows :

Use a communication line , One end is connected to DTD418M Of RJ45 Interface , The other end is connected to S7-200SMART Of RJ45 Interface .

The equipment commissioning mode is as follows: :

Controller configuration :

1. Open Wizard , Double click the figure below PROFINET

2. Check the controller , Set up the controller IP Address , Subnet mask and station name , Click next

3. Select the smart device to be configured from the directory on the right and drag it into the corresponding slot , Set the device name ( It must be consistent with the actual smart device name )

4. Simple setup of the main program

5. Download the program into PLC in
