Case study

A global pulp & paper corporation wanted to apply common tools and procedures for loop tuning in 40 plants around the world each with different control systems and IT architectures. 

Problem -A few company-wide engineers managed those tools and procedures.  The effort to support multiple applications at multiple sites around the world became too cumbersome and time consuming. They wanted to minimize the installation and maintenance effort, and ensure cybersecurity guidelines were met.  This could allow them to focus on the core need to improve process performance.


Solution - Metso proposed Global Loop Optimizer (GLO), a web-based software service.  With GLO, users can tune loops at any plant around the world. A user can view live trends, historical trends, and previous tuning work in seconds. History is maintained for every loop and each tuning activity is preserved in an electronic log book.

Centrally managed system administration greatly reduced the time and effort required to support loop tuning.  Corporate cybersecurity guidelines were applied at the server level; eliminating the need to manage application security across 40 plants.  

For plant engineers, loop tuning is made simple in GLO.  Experienced engineers and newcomers benefit from point-and-click tuning, AUTO or MANUAL mode model identification, and recommendations for optimal P, I, D and filter values.  Risk is minimized as the engineers simulate tuning response to set-point changes, load disturbances and noise without upsetting the control system. 

Metso’s consultants trained the corporate technical team, who then rolled out training to the plants around the world.  Ownership for software and server administration was transferred to the corporate IT function.

Outcome - System administration now requires much less time.  With responsibilities split between IT and control engineering, each group now focuses on their area of expertise.  Plant engineers are freed from administrative tasks and can focus on improvements.  Corporate and plant engineers collaborate more effectively because they can both work on a common system.
