See the upset before it becomes an event.
Nexus rtOpX gives the console operator early event detection and diagnostics — the developing problem, its probable root cause, and the response your own best practices call for, while the deviation is still small enough to correct.
A week of unscheduled downtime is worth a year of advanced control benefits. Nexus builds for the week you never have.

The mechanism
Conventional alarms watch single parameters against fixed limits, so they fire once severity is already climbing. rtOpX applies multi-variable logic across the unit, then attaches a probable root cause — turning an alarm into a diagnosis the operator can act on.
The need
Five pressures show up in nearly every conversation we have with a refining, chemical, or upstream operator.
A week of unscheduled downtime is worth a year of advanced control benefits.
Fewer and less experienced operations personnel need better tools to manage the process units.
Use an expert system shell to deepen the operator's understanding of control, optimization, and maintenance applications.
Deploy Process Safety Management procedures into daily operations, where they are actually used.
Scale the initial knowledge-based application to site-wide and corporate-wide deployments.
The platform
rtOpX reads the instrument, the equipment, and the operating knowledge together. A reading is only trusted once the sensor that produced it has been validated.
Continuously authenticates every measurement feeding your control system, alarms, and historian. Bad data is caught before it drives a bad decision.
5–20%
of sensors are not performing as designed
Nexus clients
First-principles and empirical models run continuously against live process data, surfacing degradation — fouling, cavitation, plugging, efficiency loss — while there is still time to act.

The return
Three places, all of them measurable, all of them reported by clients running the platform on live units.
Where it runs
Oil and gas, refining, and chemicals are where rtOpX was proven — and the same diagnostics apply anywhere a console operator is responsible for keeping a unit inside its window.
Where it continues
The Sensor & Controller Diagnostics module has been updated and is delivered today through VALID8A.AI as real-time process sensor data validation.
