Remote control method of PLC industrial control industry

With the development of industrial control towards intelligent interconnection, there are three major problems:

1. The equipment is scattered, so it is difficult to supervise the operation of the equipment on site.

2. Different devices have different protocols, interfaces and brands, which makes the connection difficult.

3. The original network structure is simple, and there is often no fixed public network IP. Fault diagnosis of large-scale equipment needs remote processing by professional after-sales personnel of manufacturers.

Aiming at the above problems, Huachen Zhitong industrial control box provides a simple, effective and flexible solution.

Realization principle of remote control in PLC industrial control industry;

The field devices and PLC are connected to the HINET intelligent gateway (or other brand gateways) through Ethernet or RS485/RS232/RS422 serial ports. HINET intelligent gateway transmits the parsed data to the Internet through 4G or wired network, and then to the server. Finally, through the data platform system deployed in the server, equipment monitoring data, business data and other data are released to the monitoring screen and various monitoring terminals. Remote monitoring of equipment can be realized through PLC cloud configuration platform.

Implementation method of Huachen Zhitong:

Product features of Huachen Zhitong industrial intelligent gateway;

1, Huachen Zhitong industrial plc edge computing gateway has powerful edge computing capability, which can realize local data processing, local pre-analysis, real-time fault warning and real-time interaction with remote data.

2. Huachen Zhitong Industrial plc Gateway provides various data transmission modes such as 4G, WAN, LAN and WiFi, and integrates various transmission modes.

3. PLC programs can be downloaded remotely through Huachen Zhitong networking gateway, which reduces equipment maintenance costs and improves efficiency.

4. Support the mainstream interfaces in industrial control industry, such as RS232, RS485, RS422 and Ethernet interfaces. , and has strong access and processing capabilities.

5. Huachen Zhitong Internet of Things Gateway can not only realize remote configuration, but also receive short messages. It can not only query the real-time analog and switch values of PLC at any time, but also realize remote configuration modification and remote parameter configuration of PLC through short message commands.

HINET industrial intelligent gateway is a device communication terminal product that integrates various Internet communication technologies and faces the industrial field. Support 4G, WIFI, Ethernet and other Internet access methods.
