SCADA technology helps utility stay on top of these advancements, allowing better planning and budgeting for required updates as the system ages.

FREMONT, CA: Like any modern technology, SCADA software and hardware standards are rapidly changing. To assist your utility in staying on top of these developments, allowing you to better plan and budget for necessary updates as your system ages and your utility's needs expand. The application of SCADA technology helps in simplified data center management. SCADA systems efficiently preserve data, making it more accessible (retrieving data from an old system can be time-consuming) and providing a wide range of data collecting methods, allowing users to quickly and efficiently access and purpose any data.

Flex licensing/ Subscription

Historically, municipal water/wastewater systems had to buy their (expensive) SCADA software, and constrained budgets made covering critical updates extremely difficult. Many SCADA companies now provide subscription and flex licensing alternatives. Subscription licensing enables your utility to lease its SCADA software license for a fraction of the cost of purchasing it outright (like renting a car). Flex licensing is a mix-and-match purchasing mechanism that allows utilities to altering software licenses without incurring penalties.

High-performance human-machine interface (HMI)

The architecture of your system's HMI (particularly the panels and graphic displays) can significantly impact your ability to manage operations successfully, especially under stressful situations. With full displays, traditional SCADA systems attempted to present too much information. It hampered the operator's ability to promptly assess the system's performance, resulting in inadequate problem prevention and resolution.

Unsafe software

For emergency notifications, SCADA system alarming software has replaced chiefly traditional telephone dialers. These applications enable the operator to maintain constant communication with the system by providing alert notifications by voice/analog/VoIP, email, text, and mobile apps.

5G and cellular

Cellular data subscriptions are becoming increasingly affordable, making them a viable alternative to traditional radio communications. Cellular can significantly expand your coverage area, particularly for facilities with limited radio availability in low elevations. It can also be utilized as a supplement to radio site-by-site.


Virtualization servers enable many operating systems to operate on a single computer simultaneously. It lowers capital and operating expenses while creating more simplified processes that ensure system redundancy. It reduces or eliminates downtime while increasing IT productivity, efficiency, agility, and responsiveness. Virtualization also allows for faster application and resource provisioning and improved business continuity and disaster recovery.

Historian of high-performance processes

The process historian captures all of your system's data. The utility of this detailed data extends far beyond essential system trend monitoring. A process historian is included in every SCADA system. It enables your utility to monitor data in real-time and delivers predictive analytics and regression analysis to inform your operator days or weeks before a system failure. It allows operators to study and interpret data without the assistance of a coder.
