A typical DTU (Data Transfer Unit) usually integrates multiple functions to bridge data between industrial field devices and remote monitoring platforms. Tespro’s DTU further incorporates more specialized features optimized for Industrial IoT applications.
Core functions of a DTU include:
- Data Acquisition: Collects data from various sensors, PLCs, meters, RTUs, and other devices through serial ports (RS232/RS485/RS422), Ethernet, and other interfaces.
- Data Transmission: Transmits collected data to remote servers or cloud platforms via wireless networks (e.g., 4G/5G/NB-IoT/LoRa) or wired networks (Ethernet).
- Protocol Conversion: Supports standard industrial protocols such as Modbus RTU/TCP, DL/T 645, and can parse and convert private protocols as needed, enabling interoperability between different devices.
- Heartbeat Mechanism: Periodically sends heartbeat packets to the server to maintain connection status and detect network connectivity, ensuring the device is online.
- Auto Reconnect and Data Resend: Automatically reconnects after a network interruption and resends data that was not sent during the interruption, ensuring no data loss.
- Remote Configuration and Management: Supports remote parameter configuration, firmware upgrades, restarts, and other operations via a remote platform, facilitating large-scale deployment and maintenance.
- Local Storage: Some DTUs have local data storage capabilities, allowing data to be cached during network anomalies and uploaded once the network recovers.
- Security Encryption: Provides security mechanisms such as VPN, APN private network access, and data encryption to ensure the privacy and integrity of data transmission.
- Indicator Light Status Display: Visually displays working status such as network connection and data transmission through LED indicators.
- Industrial-grade Design: Adopts wide temperature, wide voltage, and EMC protection designs to adapt to harsh industrial field environments.
