Node-RED makes it easy to create dashboard interfaces as it is using the node-red-dashboard node.īut what about SCADA-like graphics that mimic processes like the one below? With this framework, you can visually wire together protocol nodes, like MQTT and Modbus, data manipulation processing nodes, and output nodes like dashboards and user interfaces, creating the so-called “flows”. Node-RED is a popular flow-based programming tool that has powerful IoT capabilities. #SCADA #IOT #IIOT #OPENSOURCE #HMI #MONGODB If you think this is meaningful, please check the project repository hereĬontributions are always welcome in any form, like help with translation, testing, coding, feature ideas, etc.Ĭopyright © 2020 Ricardo L. The system should grow fast from now on in terms of capabilities and the completion of its protocol suite. The foundations of JSON-SCADA are strong and future-proof. For control centers, it requires some more work, but it is to be put on production in just a few months. JSON-SCADA was already deployed successfully for local substation HMI. With this strategy, in less than one year, it was possible to develop a new system from scratch. It also brings powerful capabilities and tools, integration with many programming languages, and a healthy community for support. It allows for effortless portability, high availability, and horizontal scalability. This decision has simplified the development by an order of magnitude. Just use the right tool for each job.Ī new innovative architecture was designed, using MongoDB as the real-time database and persistence layer. I think an adequate approach can be to create a new system by combining the best available open-source tools, not reinventing the wheel.

However, open-source standalone tools like PostgreSQL/TimescaleDB, Grafana, MongoDB, Nginx, InfluxDB, and protocol stacks like OpenDNP3, lib60870, lib6150 are of such high quality that it is difficult to match for any proprietary software tool. Hopefully, there are some promising options in the open-source SCADA/IoT ecosystem, like SCADA-LTS and EdgeX Foundry. Even political motives can be a hindrance in some countries for closed source software packages. Commercial software is not modifiable, is not transparent, is not agile enough. Other smaller providers can do a better job, but the commercial model is too restrictive. Many software packages are provided by big companies that just do not have the necessary agility and courage to abandon old software and start from scratch. When I say traditional, I mean traditional architecture and a traditional commercial business model. It is also quite clear nowadays that traditional SCADA systems cannot deal well with the new requirements of Industry 4.0, IIoT, Big Data, IA/ML, cloud, cybersecurity, etc. To expand its capabilities to support more advanced functionality would be too difficult.

OSHMI is just HMI software, it is not a full SCADA system. The in-memory real-time core is monolithic, difficult to understand. In this article, I will try to put in words the rationale for creating a brand new open-source SCADA/IoT system.Īfter more than ten years of experience developing and using the OSHMI open-source HMI system, I realized that it is too difficult to maintain and expand.
