Industrial Control Wireless Networking Solution

Industrial control sites usually have harsh environments, high temperature, humidity, vibration, and serious interference from the power grid. Especially in the electromagnetic and radio interference environment, electromagnetic shielding and physical protection are required for long, continuous, reliable and complete data transmission. In some industrial environments, such as moving or rotating equipment, routing is very inconvenient.

The CM580-21F 3G/4G wireless industrial computer uses the transmission technology to replace the industrial control field cable for measurement and control solutions, which provides a solution to the problems in the bad environment data transmission. This solution uses the Internet server to pass the wireless. The method is to remotely control the industrial site, regardless of distance and networking.


System composition

The whole system in this scheme consists of user equipment, CM580-21F 3G/4G industrial routing and server. The server establishes a connection with the CM580-21F 3G/4G industrial router through the Internet network, and the 3G/4G public mobile network is directly connected to the PLC located in each industrial site through the serial port of the wireless router (RS-232/485/422) remote control of the PLC.
