IoT gateway

Cloud-enabled industrial micro computer

To facilitate the adoption of IoT, Advantech (Taiwan) has developed its smallest industrial IoT gateway: the UNO-1251G is as small as a micro PLC and is DIN-rail mountable. It has built-in CAN.

To aid accessibility, the industrial computer comes with a programmable OLED display, a wireless communication slot, and built in CAN. It supports over 450 PLCs, controllers and I/O devices protocols with web access/HMI software.

With an integrated CAN connector, the UNO-1251G is especially suitable for networking I/O devices such as sensors and actuators. CAN 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 CAN applications, the gateway includes the Advantech CANopen Protocol Library, which provides a C application programming interface (API) with which to use, configure, start, and monitor CANopen devices. The gateway’s CAN port has a bit-rate of 10 kbit/s to 500 kbit/s.

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

The programmable 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 gateway 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. Other available interfaces are EiA 485, EiA 422/485, and EiA 232.

The gateway supports WEC7 and Linux as operating systems. Encased in an aluminum housing, the device weighs 0,4 kg. It withstands an operating temperature of -20 °C to +60 °C.
