Due to a wide range of possible use cases, it’s difficult to talk about specifics, but there are a few universal elements and characteristics that should be included in every system.
Easy customization
SCADA software is rarely used by one department or role. More often than not, there will be elements in the system that are crucial only to a few people. So, depending on a specialist or purpose, a SCADA interface should be easily customizable to provide users with exactly the type of information that they need without the overload of unnecessary data.
The ability to present and analyze historical data
The analytical capabilities of SCADA systems are one of their key values. Thanks to them, companies can reduce costs, detect and eliminate bottlenecks and make much better decisions.
Of course, as long as the system interface provides them with sufficient tools to analyze and present the data.
Scalability
The fact that a SCADA interface is easily customizable makes it significantly easy to expand. As the facility grows, more devices and sensors will be connected, and more users will need the system to work according to their needs.
Accessibility
Modern SCADA systems can be built as web apps, which can be launched on different devices, including mobile phones and tablets.
Legibility
Reaction speed matters in environments that use Scada systems. That’s why the operator must be able to interpret every type of data and the status of components & devices in a split second.
No distractions (focus)
The interface is usually displayed 24/7 in the control room, so there is no need for animations and other distractors that are dragging your attention from essential things (real-time data).
Conservative pallet of colors & icons
Colors are usually standardized & associated with statuses, so the interface scheme shouldn't interfere with that. Icons are often taken from the documentation or industrial standard (like symbols in electrical circuits).
Simple to the bone
Micro-interactions, animations, detailed illustrations & renders - usually all eye-pleasers are secondary when setting a budget for the SCADA interface. But sometimes, using those elements can be justified, especially when it serves the user story (or some operator routine), or when you sell the system to the customer.
Schematic
A good SCADA should picture the real estate layout of devices and sensors in the system, so the operator can know exactly where the error occurred.
