With the development of the Internet, the coverage of the Internet has become wider and wider. Internet communication has become an indispensable part of everyday life because of its characteristics of convenience, efficiency, reliability, and low cost. It has also become a better choice for data communication in industry.
Some industrial equipments do not have the ability of network communication because of itself, which brings great inconvenience to real-time control and centralized management of equipment. This problem is particularly acute when the equipment is widely distributed. This article takes a company's use of DC-N2100 remote control electronic energy-saving equipment as an example to introduce the DC-N210 in the remote device control application.
In this application case, a company has a large number of branches and distributions in major cities throughout the country. For example, branches use some electronic energy-saving equipment to save the company's electricity consumption. How to effectively manage these devices becomes a problem. The electronic energy-saving device has an RS485 communication port, and the device information can be read or set through the RS485 interface. The communication distance of the RS485 interface is 1200 meters. Up to 128 RS485 interface devices can be connected to form an RS485 network. The DC-N2100 has an RS485 communication interface with a communication rate of 300 pbs to 115200 bps and can be connected to these devices. With the DC-N2100, you can connect your on-site electronic energy-saving device to a remote server. The system structure is as follows:
The DC-N2100 works in the client mode. After it is powered on, it actively connects to a remote server. The DC-N2100 can organize the uplink data of field devices into IP packets and send them to the server, and can forward the valid data in the received IP packets of the server to the field devices. This establishes a data transmission channel between the field device and the server.
In this system, another important role is a workstation, which can use a computer that can connect to the Internet to perform this role. The workstation runs the management program and connects to the remote server. In this way, the workstation can communicate with field devices through the server.
The above applications take place in the wide area network. The DC-N2100 and servers, workstations and servers comply with certain agreements, enabling the server to correctly forward data from the workstation to the target device and correctly forward the uplink data to the workstation. on. This enables remote centralized management of devices.
