Nexus OnCore Control System

When a plant fails to operate correctly, Nexus OnCore Control System is there to help plant operators improve their decision-making speed and accuracy.

The unified software environment quickly and accurately changes the application system logic that controls plant operations in real-time, online.

This capability found with Nexus OnCore Control System optimizes up-time without the need to rely on the manufacturer.

Nexus OnCore Safety System

Nexus OnCore systems increase equipment availability, reliability, and maintainability for rotating machines by offering a portfolio that includes critical cybersecurity features and a diagnostic approach to the OEM system vendor.

The Nexus OnCore Safety System is an electronic safety-related system defined by IEC 61508 (2010), with a system capability of SC 3 and a safety integration level of SIL 3 by 2oo3 architectural design.

It can be applied to those applications which require no higher than SIL 3 under low-demand operation mode.

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.

OnCore Control System Architecture

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?]

The Nexus OnCore Control System helps plant operators improve their speed and accuracy in making critical decisions when the plant fails to operate under normal conditions

OnCore Control System Overview

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.
