Metso Expertune PlantTriage v18 control loop monitoring software

Metso has announced a new version of its Expertune PlantTriage control loop monitoring software. The latest version further improves process plant operational efficiency, reduces cybersecurity risks and helps to improve profitability.

This version provides a clearer view of PID (proportional-integral-derivative) tuning benefits via a new Performance Evaluation dashboard and a Performance Summary panel. These features show the effect new tuning parameters will have on valve duty, relative response time, robustness and performance.

In addition, the PlantTriage Level Wizard is an advanced tool that tunes level controllers for surge tanks. The purpose of surge tanks is to maintain a constant flow to the next stage of the process. Proper tuning guarantees maximum use of surge, while preventing the tank from emptying or overflowing. The Level Wizard helps to get the balance just right.

Expertune PlantTriage is designed for identifying the root causes of control system performance issues. Version 18 offers interaction analysis with greater resolution. Two analysis tools, Process Interaction Map and Interaction Hot Spots, are used to find the underlying root cause of an upset or event. Users can now find both short- and long-term interactions, ranging from 1 min to as long as 14 days. These tools can pinpoint the root cause of a specific incident, and help in analysing short duration or sporadic events.

The latest version also includes advances in cybersecurity. Users may now choose encryption on communications with PlantTriage servers. Other improvements make the browser interface more secure, robust and less vulnerable to attack.
