Our Approach to Distributed Control Systems & Key Benefits

Distributed Control Systems are powerful tools to help operators improve visibility to their assets, increase response speed and accuracy when the plant fails to operate under normal conditions, and greater transparency to operations with advanced analytical capabilities. At Nexus, we’ve been working with a range of control systems technologies for decades, helping customers with installation, upgrades, and services.

Through this work, we recognized our customers were facing consistent pain points with their systems: complex licenses packed with additional fees, unnecessarily complicated user interfaces making learning the system onerous, costly system shutdowns for module replacements, among others. This led us to develop the Nexus OnCore† Control System.

The Nexus OnCore Control System is an advanced, fully configurable solution that improves asset visibility, provides built-in troubleshooting and maintenance tools, offers simplified expansion capabilities, and reduces overall installation and training costs.

Our redundant I/O communication and power enable independent module replacement without a total system shutdown. Additionally, a three-level system network provides real-time performance with high-speed data exchange where you need it most – between the controller and HMI. [potentially add more here?]

Nexus OnCore HMI software (OptimumC) offers a unified software environment with the ability to quickly and precisely make online changes to the application system logic that controls the plant’s operations. This capability optimizes the amount of time necessary to correct the situation without having to rely on the manufacturer. This gives you the flexibility to manage your operations on your schedule.

Our integrated HMI software package includes an embedded historian that can be expanded without additional equipment, saving cost and allowing for more analytical capability.

Easily configured software allows for customization of HMI screens, reducing training time while improving the user experience.

A simplified, single license that covers all aspects of your process control and safety system means no additional license fees are required in the future if you choose to add points, cards, or expand the capability of the integrated data historian. This flexibility is particularly important as many industries accelerate their digital transformation journey.
