4G wireless industrial routers can provide PLC system engineers with remote access to their PLC systems through the Internet, which not only eliminates the need for manual back and forth, but also makes it more convenient to maintain machines, thereby saving time, manpower, and material resources, and providing customers with quicker assistance and reducing customer losses. At present, PLC remote still has existing problems and an urgent need to solve them.
In industry, the use of 4G wireless industrial routers and PLCs to achieve remote control has become a new application. This post shows the use of 4G wireless industrial routers to achieve Siemens, Mitsubishi, Omron, Delta, and other models of PLC remote monitoring and downloading.
Currently, the PLC remote is commonly used for mapping IP addresses, VPNs, peanut shells, peanut bars, etc., but also to set some complicated parameters, etc., and the interface is difficult to use and unstable. The use of Alotcer SmartLink technology makes the remote control of plc much easier and more convenient.
Alotcer industrial router is a 4G industrial grade wireless router specially designed for PLC to download and monitor programs remotely via a network port or RS485/RS232 bus. Communication methods include 4G wired or wireless, which enables PLC’s remote monitoring ladder to be realized and the program to be downloaded.
Alotcer industrial router and PLC through the network port or RS232/RS485 bus interconnection, you can remotely monitor ladder diagrams and download programs through PLC programming software, supporting communication protocols including Siemens, Mitsubishi, Omron, Delta, and other general PLC, connection mode: with 4G and wired interface, the PLC site with 4G network or wired can be. Connected through a serial port (485, or 232 are available) and the site PLC programming port. The remote computer only needs to have Internet access, no fixed IP, and only needs to install Alotcer’s SmartLink green software, and install the PLC programming software to download the debugging program remotely.
PLC remote example
Alotcer and PLC are interconnected through 232 bus, then through 4G or ADSL wired Internet access, the central side can also monitor ladder diagrams and download programs with PLC programming software as long as it has Internet access, and the supported communication protocols include Siemens, Mitsubishi, and other general PLCs. A serial port, open the programming software and select the virtual serial port.
Remote control of plc through RS232 serial communication
Configure Alotcer industrial router in the same SmartLink LAN
Configure the Alotcer industrial router to have a serial port
Install the virtual serial port on the local computer
The virtual serial port is installed successfully
Configure the computer side SmartLink green software
Ping the SmartLink IP of the router on the computer
At this point, the router and the computer have been pinged through, indicating that the router and the computer are in the same SmartLink LAN
Perform communication settings
You can now remotely control the plc from your computer, allowing the ladder to be downloaded and monitored.
