How to upload PLC data to the server

Three steps of PLC wireless data:

Data collection terminal, wireless transmission, data receiving terminal.

Many automatic control systems now require remote control.

With the development of the Internet of Things technology and the popularization of information technology, more and more PLC, HMI and other automatic control product manufacturers or integrators urgently need to remotely monitor, debug and maintain field equipment.

Remote monitoring can reduce the cost of manpower travel and reduce the time of engineers on the road;

From the technical aspect, remote control realizes the equipment networking function and realizes the industrial Internet of Things guarantee.

Therefore, three links of communication are required to be two-way.

Among these three links, the most critical is the data collection terminal. The wireless data collection eventually needs to support the PLC communication protocol, and it needs to be able to communicate with the receiving terminal wirelessly.

How can the collection terminal be connected wirelessly to the terminal and can be identified? There is no need to apply for a fixed IP, and the configuration is very simple and convenient.

Technology deployment

A Tashi industrial router or DTU is configured at the front end. This configuration is not limited in the collection frequency and communication volume, and the reliability and stability of the network are relatively poor, but the cost is low and it can be quickly set up.

Or use an industrial router to configure a VPN server on the central side, and build a local area network in the wide area network through VPN technology. The operating computer and network equipment can be connected to any one of the gateway devices through WIFI or LAN, and you can access all the devices and devices in the local area network. computer.

Relatively speaking, the reliability and stability of the network will be better.

According to the communication protocol provided by the PLC communication module or the CPU module, the received data message transmitted by the front-end monitor is analyzed, and then packaged according to commonly used industrial standard protocols, such as OPC and other protocols.

Of course, if anti-control is implemented, the data message sent from the PC will be parsed according to the previously packaged protocol, and then packaged according to the on-site PLC protocol and then sent to the front-end equipment.
