Implementation plan and case analysis of plc industrial router 4G

4G wireless industrial grade routers have been widely used in the industry. For PLC engineers, remote access to PLC systems via the Internet can not only eliminate manual back and forth time, but also maintain machine problems in a timely manner. Saving time, manpower and material resources can also provide customers with faster service and reduce customer losses. At present, the problem of remote PLC still exists urgently needs to be solved.

4G wireless industrial grade router and plc realize remote control has become a new application in the industry. The following is the principle of PLC remote control and the use of Huajie intelligent control HJ8300 4G wireless industrial grade router to realize Siemens, Mitsubishi, Omron, Delta, etc. A variety of PLC remote monitoring and download methods.

At present, PLC remotely adopts the methods of mapping IP address, VPN, peanut shell, peanut stick, etc., and also sets some complicated parameters. The user is very troublesome in use and unstable. Utilizing Huajie intelligent control smartlink technology, the remote control of plc is more simple and convenient.

Huajie Intelligent Control HJ8300 Industrial Router is a 4G industrial grade wireless router dedicated to PLC remote download and monitoring program through network port or RS485/RS232 bus. It uses 4G, wired or WIFI as a communication means to realize the remote monitoring ladder diagram of PLC and download the program.

The Huajie intelligent control HJ8300 industrial router and PLC are interconnected through the network port or RS232/RS485 bus. The ladder programming can be remotely monitored through the PLC programming software, and the program can be downloaded remotely. The supported communication protocols include Siemens, Mitsubishi, Omron, Delta, etc. PLC, connection mode: HJ8300 has 4G and wired interface. The PLC can have 4G network or wired at the site. HJ8300 can be connected to the PLC programming port through serial port (485 or 232). The remote computer only needs to be able to access the Internet, no need to fix the IP, just install the smartlink green software of Huajie Zhikong, and install the PLC programming software to download the debugging program remotely.

PLC remote instance

Huajie intelligent control HJ8300 and PLC through 232 bus interconnection, and then through 4G or ADSL wired Internet access, the central end as long as the Internet can be used to PLC programming software monitoring ladder diagram, download procedures, support for communication protocols including Siemens, Mitsubishi and other general PLC. The operation steps are also extremely simple. After installing the configuration software provided by the company, after simple configuration, virtualize a serial port, open the programming software, and select the virtual serial port.

Communication via RS232 serial port remote console up to plc model DVP16ES200R

Configure Huajie intelligent control HJ8300 industrial router under the same smartlink LAN

Configure the serial port of Huajie Zhikong HJ8300 industrial router

Install a virtual serial port on your local computer

The virtual serial port is successfully installed.

Configure computer-side smartlink green software

Ping the router's smartlink IP on your computer

At this point, the ping has been completed, indicating that the router and the computer are in the same smartlink LAN.

Make communication settings

You're done, you can reach the plc on the remote console of the computer, and realize the download and monitoring of the ladder diagram!
