Advantech Launches Cloud Enabled Micro IoT Gateway Industrial Computer

Advantech-UNO-1251GTo facilitate the adoption of the IoT, Advantechs IIoT Automation Group has developed its smallest DIN-rail mountable IoT Gateway, the UNO-1251G, which is as small as a micro PLC. To aid accessibility, the industrial computer comes with a programmable OLED display, easily accessible wireless communication slot, and built in CANbus. It supports over 450 PLCs, controllers, and I/O device protocols with WebAccess/HMI software.

With an integrated CANbus connecter, the UNO-1251G is especially suitable for networking intelligent I/O devices such as sensors and actuators. Originally, designed by Bosch, CANbus is characterized by its multi-master protocol, real-time capability, error correction, high noise immunity, and the existence of many different silicon components. To aid development of CANbus applications, the UNO-1251G includes the Advantech CANopen protocol library, which provides a C application programming interface (API) with which to use, configure, start, and monitor CANopen devices.

To aid internet connection in areas where using wires is impractical, the UNO-1251G includes an easy accessible side mounted expansion slot which can be used for installing an optional wireless card without having to open up the entire unit. The UNO-1251G has been designed to be operated remotely from any computer or table with a VNC (Virtual Network Computer) client installed and engineers can remotely access the UNO-1251G for diagnosis and control from wherever they are located. Through WebAccess, it helps move from proprietary systems to an open architecture and eases the integration of different devices.

The programming OLED display provides operators with intuitive system status messages. It comes with a range of default messages but is also able to be programmed using the OLED display API by site engineers so specific messages can be shown.

As well as the RISC 32 bit ARM Cortex A8 processor, the UNO-1251G also includes externally accessible micro SIM for 3G access and a micro SD card slot for additional storage, USB port, two 10/100 LAN ports, LED indicators, integrated 1G micro SD card with OS installed, and three COM ports.
