Welche Arten von Gateways werden üblicherweise für die Fernsteuerung von SPSen verwendet? Wie wird die Fernüberwachung von SPSen realisiert?

Commonly used gateway types for PLC (Power Line Communication) remote control mainly include the following:

Ethernet gateway: Converts PLC signals into Ethernet signals to realize the interconnection between PLC and Ethernet, so that the PLC system can be remotely controlled and monitored through the network.

Wireless gateway: Converts PLC signals into wireless signals to realize the interconnection between PLC and wireless networks, so that the PLC system can be remotely controlled and monitored through the wireless network.

RS485 gateway: Converts PLC signals into RS485 signals to realize the interconnection between PLC and RS485 network, so that the PLC system can be remotely controlled and monitored through the RS485 network.

GPRS/3G/4G gateway: Convert PLC signals into mobile communication signals to realize the interconnection between PLC and mobile communication network, so that the PLC system can be remotely controlled and monitored through the mobile communication network.

PLC remote monitoring can be achieved through the following steps:

PLC signal collection: Collect PLC signals through a PLC collector, including sensor signals, control signals, etc.

Data transmission: Convert and transmit the collected PLC signals through the Gateway-Gerät. You can choose Ethernet, wireless, RS485 or mobile communication for transmission.

Data processing: Process and analyze the transmitted PLC signals to obtain real-time status data, alarm information, etc.

Data storage: Store the processed data in the database for subsequent query and analysis.

Data display: Use data visualization technology to display data stored in the database, including real-time data, historical data, trend analysis, etc.

Remote control: Remote control of PLC through remote control system, including switching, adjustment and other operations.

Through the above steps, remote monitoring and control of the PLC system can be achieved. Commonly used gateway types for PLC remote control . Different types of gateways can be selected for application according to actual needs. Remote monitoring can realize real-time monitoring and data analysis of the PLC system, helping users find and solve problems in time; remote control can realize remote operation of the PLC system, improving operating efficiency and safety.
