THANK YOU FOR SUBSCRIBING
For more than three decades, SCADA/HMI applications have played a vital role in manufacturing, but the challenges await industry 4.0 are unknown.
FREMONT, CA: Supervisory, Control, and Data Acquisition (SCADA) are supervision systems that enable the users to monitor how the states of controlled processes evolve. They provide all the functionality needed to view and supervise real-time information on the processes' actual status. Furthermore, they help to access and manage the historical records and the exceptional states.
The Industry 4.0 paradigm poses many issues for this technology. From the user interface to a web technology integration, here are some of the primary needs of SCADA/HMI solutions of the future.
The integration between IT and OT is crucial in the smart factory. With Industry 4.0, there is a growing flow of data between more connected and heterogeneous subjects, in and out of the production plant.
Industrial PCs or HMIs along with two Ethernet ports, connect the corporate IT network and the machine's OT automation network.
New generations of SCADA must be created with the latest digital technologies in mind. This means that SCADA/HMI solutions should be based on the same web technologies that we use every day to ensure more excellent compatibility. The only requirement is a compatible HTML5 browser.
The new SCADA/HMI technology, hardware mounted on the machine, is replaced with a component with no user interface installed inside the panel. Once the production information is collected, then this component will:
• Make them usable with the use of Wi-Fi devices in the system. In this way, operators can approach the machine and see their tablet or smartphone the pages to manage the machine.
• Or, send them to the Cloud to be shared with high-level application.
