Providing connectivity for the Internet of Things
ATOP’s Industrial Embedded Computer is your ideal flexible Gateway to the Internet of Things, specifically tailored for advanced Power Substation applications. It provides Serial, Ethernet connectivity and interfaces that can unlock your potential. Based on your specific application, it allowing almost any serial device to be connected, providing and retrieving the data you need to and from the cloud, no matter what provider you’re using.

Write your customized application in C language and Run it on its powerful Industrial low-power 1GHz ARM Cortex A8 TI Sitara AM3352 CPU. Make flexible use of your peripherals, no matter storage, Serial, or USB are needed.
The device is available as a Standard SDK or Node-RED version.
The Node-RED version, embedding a Node-RED SD-card, adds to the powerful hardware platform, the possibility add the ATOP-Customized Node-RED environment and an user-friendly Device Configuration UI. Node-RED, an open source Building-Block programming environment, will allow you to build your IoT application from an user-friendly, hardware-tailored application design environment and dashboard.NodeRED has already all you need.

Rugged and flexible for advanced developments
SE5908A embed high EMC protection, wide temperature operation, programming and installation flexibility in one device. The IEC61850-3 certified hardware makes it the most advanced Computing option, while the dual power supply provides additional redundancy in case of power failure. High-Voltage option makes the device suitable for High-Voltage AC or DC inputs (100~240 VAC or 100~370VDC) that are common in substation environments., without additional cabling and power supply.

The IoT (Internet of Things) or IIoT (Industrial Internet of Things) is a trending topic these days. It’s all about bringing devices, sensors, actuators, data and commands to the cloud, with the ultimate goal to improve the quality of life, the services Smart Cities can offer, saving energy or saving money. This requires two things: to vehiculate the collected data to the cloud in a format that can be recognized and processed and to process, compute and analyze all this amount of data in real time.
It is not a concept far from reality. Imagine you’d like to bridge a Modbus Sensor to the cloud. And you’d like to have the application running on the cloud to be able to process multiple sensors’ data, and to trigger some event in some specific stations along the network. You may also have the need to override the cloud control and manage the application locally. Any application has its story.
Here at ATOP, we understand these different needs and we are providing you different working models, based on what your needs are.

Use the Standard SDK, programmable embedded computer if:

  • You are familiar with Linux OS
  • You have ANSI C programming skills
  • Your application is strictly time/ performance sensitive
  • Your application has very critical exception handling requirements

Our SDK products provide:

  • Ported, proven and tested peripherals (such as Relay, Ethernet, Serial, etc.) and integrated drivers
  • ATOP customized Linux Kernel and network protocols
  • Ported, debugged and proven third party applications
  • Utilities and APIs to control the hardware in an easy and effective way
  • Example of source code

Use ATOP’s Node-RED version with the embedded SD-card if:

  • You’re hands-on, with a good understanding of protocols, data formats
  • You have some basic Javascript knowledge
  • You’re looking for a simple, user-friendly and effective way to deploy  your applications to the cloud, with a user friendly monitoring dashboard
  • You don’t have strict performance requirements, and exception handling  is not critical

Our Node-RED version provides:

  • • Node-RED visual application development environment and dashboard,
    with automatic start on device boot-up, Node.JS based
  • ATOP-customized dedicated Web-UI for user friendly device set-up, allowing you to create VPN tunnels, set-up the network or the Cellular settings, date/ time, diagnostics and much mode without using Linux command line.
  • Different level of security to allow developers to access development  environment and users to access dashboard only
  • Customized Node-RED APIs (blocks) that will allow you to fully control ATOP powerful hardware and control relays, Buzzer, diagnostics and much more
  • Integrated Modbus and MQTT stacks, for seamless communication with field devices and cloud
  • Integrated AWS, Azure, Google and IBM Bluemix Nodes.
