4G LTE modem typically supports multiple communication protocols, which makes it highly flexible and compatible.It can meet the communication needs of different devices and systems. The following lists the applications and functions of various protocols of 4G LTE modem:
Modbus is a commonly used industrial communication protocol for communication between different devices.The 4G LTE modem supports the Modbus protocol and can be used as a Modbus master station or a Modbus slave station to communicate with PLC, sensors, frequency converters and other devices.Realize monitoring, control and data acquisition.
OPC (OLE for Process Control) is a standard protocol for industrial automation.It is used to realize data transmission between devices.The 4G LTE modem supports the OPC protocol and can communicate with the SCADA system or other OPC servers.Realize equipment status monitoring, data acquisition and remote control.
MQTT (Message Queuing Telemetry Transport) is a lightweight communication protocol based on publish-subscribe model.It is widely used in the field of Internet of Things.The 4G LTE modem supports the MQTT protocol and can communicate with the cloud platform or other MQTT agents to realize the transmission and remote monitoring of device data.
TCP/IP protocol is a communication protocol commonly used in the Internet, which realizes data transmission between devices through the network.The 4G LTE modem supports the TCP/IP protocol and can establish a TCP connection with a remote server or other device.Realize the remote control, data acquisition and remote access of the equipment.
RS232/RS485 is a serial communication interface protocol that is commonly used for connections between industrial devices.The 4G LTE modem supports RS232 and RS485 protocols, and can exchange data and communicate with sensors, industrial computers, PLCs and other devices.
By supporting multiple protocols, 4G LTE modems enable seamless connectivity between different devices and systems.Provide flexible data transmission and communication functions to meet various communication requirements of industrial sites.Whether it is equipment monitoring, remote control, data acquisition or connection to the cloud platform,Both 4G and LTE modems provide reliable and secure communication solutions for industrial environments.
