Software Detail

Plat'Home IoT Gateway Software FW

FW is equipped with Plat'Home Data Handling Module System (PDHMS) which is basically a message handling system supporting flexible and high-speed communication between the device and the cloud. PDHMS is also a system designed to realize inter-process communication flexibly and at high speed among application modules inside the IoT Gateway. It enables the implementation of application modules of various functions on the edge side, realizing flexible and high performance IoT edge computing. PDHMS supports multi-devices and multi-clouds, and is capable of responding flexibly to a variety of IoT system needs of the customer.


OpenBlocks® IoT VX2 comes with a pre-integrated Plat'Home IoT Gateway Software called "FW" It offers full support for the intelligent IoT edge computing, including sensor, device and cloud service connectivity settings, Docker container deployment and allocation resource settings as well as Microsoft Azure IoT Edge Monitoring and Runtime updates via visually operable Management UI.
Additionally, it facilitates direct data communication between Plat’Home Gateway Data Handling Module System (PDHMS) as below and Azure IoT Edge enabling data collection from the IoT device and bidirectional communication with the cloud. It also adds a near-real-time data analysis capability to that which is located closer to IoT leaf devices in order to enrich big data analytics performed in the cloud.

Plat'Home Data Handling Module System(PDHMS)

The system architecture of PDHMS is designed to enable a flexible and high-speed inter-process communication among application modules inside the IoT Gateway of VX2**. Application modules with various functions can be installed on the edge side, thereby ensuring flexible edge computing.


A group of applications to acquire data from sensors and other IoT devices using BLE or UART (serial communication, etc.). They support a wide variety of IoT devices, while also supporting an extension of IoT device control applications of Lua language* by users.

  • *Lua language: A script language featuring high-speed operations and easiness of integration.
  • **PD stands for Plat'Home Data.Same as bellow.

Management UI

The web-based Management UI is to carry out search of the sensors and beacons along with their pairings, connection setups with cloud services offed by different service providers. It also sets up and carries out the operation of IoT communication functions through the web browser screen. When IoT goes live, knowledge of command lines is not required, hence the engineering burden will be alleviated.

Docker management from Management UI

It supports Docker as an application execution environment. Docker containers can be used on OpenBlocks® IoT VX2 and also be controlled from the Management UI. In addition, they support the function to deploy Docker images released from the Docker image sharing service Docker Hub, and also to deploy them from a self-constructed private Docker image registry, thereby enabling users to make use of a wide variety of Docker images. The Management UI can also deploy Docker containers, in addition to carrying out start, stop and resource allocations.

Key functions
  • Deployment and deletion of Docker images
    • Downloading Docker images from Docker Hubs
    • Downloading Docker images from private registries
  • Start and stop of Docker containers
  • Setup of allocated resources
  • Indication of resource usage

Azure IoT Edge Management from Management UI

The IoT edge computing support software from Microsoft, Azure IoT Edge*, is supported by this product. In other words, Azure IoT Edge can run on OpenBlocks® IoT VX2, while the Management UI of OpenBlocks® IoT VX2 can monitor the status of Azure IoT Edge. Intelligent processes that are conventionally conducted via the cloud, such as Azure Stream Analytics and Azure Machine Learning, can be executed on OpenBlocks® IoT VX2 on the edge side, thereby drastically reducing device latencies and substantially decreasing communication traffic of the entire system. In addition, as FW supports direct data linkage between PDHMS within the edge gateway and Azure IoT Edge, it can also, for example, analyze sensing data collected by a wide array of sensors, devices that support OpenBlocks® IoT VX2, and it strongly supports IoT edge computing that takes advantage of Azure IoT Edge.

Key functions
  • Status monitoring of Azure IoT Edge
  • Deployment and deletion of Azure IoT Edge
  • Start and stop of Azure IoT Edge
  • Azure IoT Edge runtime update

Node-Red on the Edge

Node-RED is a programming tool that involves wiring together hardware devices, APIs and online services. From WEB UI, it can process data received from sensors and visually program it to be sent to a particular cloud service or take a particular action, allowing easy realization of edge computing for IoT. It can also employ additional functions for Node-RED that are provided by software and cloud service vendors, making the addition of various applications a relatively easy task.
