With the vigorous advancement of Industry 4.0, higher requirements have been put forward for the stability of industrial on-site equipment. At present, many equipment manufacturers still cannot continuously monitor and manage their equipment. In addition, on-site equipment is scattered in distribution, and the cost of business trips to the site is high. These problems lead to a poor after-sales service experience for equipment.
Equipment manufacturers or engineering companies need to keep track of the operating status of equipment distributed across the country in real time, including the current operating data and set data of the equipment, so as to realize intelligent operation and maintenance for production management. Therefore, remote monitoring, maintenance and remote control of equipment have become an inevitable trend. Through the remote maintenance system, engineers can timely monitor the operating status and alarm information of equipment, and technicians can maintain the equipment in a timely manner to ensure the normal and stable operation of the equipment.
In response to this, Wutong Bolian provides a PLC remote maintenance system based on industrial intelligent gateways and Device Express. On-site PLCs are connected to industrial intelligent gateways via serial ports and Ethernet ports. The gateways realize network connection and data communication through 5G/4G/Wi-Fi and other methods. Equipment manufacturers can remotely access off-site PLC equipment through Device Express, establishing a virtual local area network (LAN) between local computers and off-site PLCs. Furthermore, this enables operations such as remote uploading and downloading of programs and online debugging of PLCs on programming software, facilitating rapid diagnosis and troubleshooting, as well as quick fault repair to resume production.
