Edge Gateway usually supports multiple communication protocols, which gives it a high degree of flexibility and compatibility to meet the communication needs of different devices and systems. The applications and functions of multiple protocols of Edge Gateway are listed below:
1. Modbus protocol: Modbus is a commonly used industrial communication protocol for communication between different devices. Пограничный шлюз supports Modbus protocol and can be used as Modbus master or slave to communicate with PLCs, sensors, inverters and other devices to achieve monitoring, control and data acquisition.
2. OPC protocol: OPC (OLE for Process Control) is a standard protocol used in industrial automation for data transmission between devices. Edge Gateway supports OPC protocol and can communicate with SCADA system or other OPC servers to achieve equipment status monitoring, data acquisition and remote control.
3. MQTT protocol: MQTT (Message Queuing Telemetry Transport) is a lightweight communication protocol based on publish-subscribe model, which is widely used in the field of IoT. Edge Gateway supports MQTT protocol, which allows it to communicate with cloud platforms or other MQTT agents, and realise the transmission of data and remote monitoring of devices.
4. TCP/IP protocol: TCP/IP protocol is a communication protocol commonly used in the Internet, which realises data transmission between devices through the network.Edge Gateway supports TCP/IP protocol, which can establish TCP connection with remote server or other devices to realise remote control, data collection and remote access of devices.
5. RS232/RS485 protocol: RS232/RS485 is a serial communication interface protocol, which is commonly used in the connection between industrial devices.Edge Gateway supports RS232 and RS485 protocols, which can be used to exchange data and communicate with sensors, industrial controllers, PLCs and other devices.
By supporting multiple protocols, Edge Gateway can realise seamless connection between different devices and systems, provide flexible data transmission and communication functions, and meet various communication needs in industrial sites. Whether for equipment monitoring, remote control, data collection or connection to cloud platforms, Edge Gateways can provide reliable and secure communication solutions for industrial environments.
