How to connect mercury router to PLC
1. Take a four-port router as an example: the router port is marked as LAN, one port is connected to PC, and the other port is connected to PLC (Siemens PLC has Ethernet port or Ethernet module), and the connection is completed.
2. Configuration scheme: The 3G router connected with PLC is a dual-function router of 3G wireless and ADSL broadband, and can be connected with RCD in 3G wireless mode or broadband wired mode.
3./7 Pull the home network cable to the router and find the wan port, which is usually the first one on the left or the first one on the right of the router with color identification, as shown below.
4. Wireless serial port penetration communication, for example, two PLCs communicate through serial port RS485. After success, the communication line is cut and a wireless serial port penetration module is connected at one side to realize wireless communication.
How to realize remote Siemens PLC connection and fault diagnosis
How to realize remote Siemens PLC connection and fault diagnosis
Siemens S7- 1200PLC and SMARTIE touch screen are connected to the multifunction switch of degassing industrial control through network cable. The type A setting of degassing switch is as follows.
Plc+ Ethernet communication module+optical fiber transceiver+optical fiber+optical fiber transceiver+switch+upper computer. Can be achieved.
It is suggested to use wireless communication module and wincc for remote monitoring in the factory. Wincc remote monitoring needs a dedicated computer as a service. As long as there is a network, it can be controlled or monitored anywhere on the earth.
First of all, the remote substation is controlled by the upper computer. In this case, there are many communication modes between the master station and the substation, such as DP, Ethernet, MPI and even wireless. In this case, there is no need to connect to the network, as long as the upper computer and the master station communicate in the above way.
The realization method of "zero escape": PLC devices distributed in different locations can be mapped to different ports and have a unified IP address. Map engineer workstations in different workshops to remote desktops. Mapping PLC master control server in PLC master control room.
Methods Huachen Zhitong industrial intelligent gateway has a wide variety, which can realize PLC remote programming, remote debugging and remote fault diagnosis, and has been widely used in water treatment, transportation, construction machinery, mechanical equipment, electric power, chemical industry and other fields.

Installation authorization. Install winccsm @ rtservforsimaticcppanel authorized by Siemens on the computer. Authorized sources can be searched online. Establish contact.
Open botuV 14 software, and double-click the new device, and Bo Tu software will pop up the new device wizard dialog box.
Open the PLC equipment and network view, click the network port of 3 15CUP 1 to set the IP address for the CPU. Create a variable table, and create variables in the variable table for communication. Click on the PLC project, compile and download the PLC project (you can simulate it first), as shown in the PG/PC interface of the configuration number, search for the established equipment and download it.
Select 300PLC as the connection object and PROFINET as the communication mode, and fill in the IP addresses of PLC and touch screen.
When you open Bo Tu, you will see an Options toolbar in the window toolbar. After clicking, there will be a drop-down menu to open the first option (setting). After clicking the setting option, the project screen will appear, and then click "Keyboard Shortcut".
Wireless communication problem of Siemens PLC Ethernet
Wireless communication problem of Siemens PLC Ethernet
1, Ethernet wireless is unstable, so it is recommended to use 485 signal wireless communication module. For example, AB433A of Xi 'an Aibaolian uses 433 frequency band, which has no application and stable transmission in industrial field.
2. Considering the above factors, the PLC wireless communication team decided to use 18 Delta DTD4 18MB Siemens PLC wireless communication terminal to complete the wireless data interaction between S7- 1500PLC in the control cabinet and the conveyor tray ET200S under Profinet protocol through Rj45 interface.
3. There are many ways for Siemens to communicate wirelessly. The most stable way is to use Siemens' own industrial router and other supporting facilities, usually using RS485 bus and MODBUS protocol to complete this function. If the field wiring is inconvenient, wireless communication can also be used.
4. Most configuration software integrates Siemens' special communication protocol (such as S7 communication protocol). If you write your own monitoring software, you can use OPC or MODBUSTCP to communicate with Siemens PLC. In a word, the Ethernet communication between the third-party products and Siemens PLC can be realized conveniently.

After the connection is successful, select Authorization in step 1, right-click Transfer, select KP 1200, and click OK. At this time, the authorization will be transmitted to KP 1200, and the authorization on the computer side will disappear. At the same time, you can also check whether the authorization has been successfully transmitted on the HMI. Program configuration.
As long as the last byte of two IP addresses does not repeat. When the wireless router leaves the factory, it adopts the default AP (wireless access point) mode, and connects the router and the RJ45 Ethernet interface of S7- 1200 with a network cable to connect the power supply of the router and PLC.
The broadband network cable or cable from the cat is connected to the WAN port of the router, and the LAN port is connected to the computer. After starting the device, open the browser and enter 19 16 1 in the address bar to enter the wireless router setting interface.
Siemens 1200 series has CM 124 1 module, and Broadcom versions above V5 have Modbus master/slave station library functions, which can be directly called for programming. When using plc to send commands, use serial port monitoring tools to monitor the commands sent by plc. If the plc sends commands normally, the device will definitely return data.
Siemens Bo Tu software is a very professional plc automatic programming software.
