Control system switchover completed in
three hours
Aracruz Cellulose recently completed the physical switch-over of more than 1000 I/O points from a Fisher-Provox control system to a modern I/A Series automation system in just over three hours
Foxboro, a unit of Invensys, today announced that Aracruz Celulose, the world's leading producer of bleached eucalyptus pulp, recently established a new industry record by completing the physical switch-over of more than 1,000 I/O points from a legacy Fisher-Provox control system to a modern I/A Series automation system in just three hours and seven minutes This control system migration was performed with the assistance of Invensys migration experts at Aracruz Cellulose Fiberline B evaporation unit at the company's world-scale pulp mill in Espirito Santo State, Brazil

"This sets a clear record for Foxboro, and - to the best of our knowledge - for any controls vendor at any customer site anywhere in the world," said Mike Caliel, president of Invensys Process Systems.
"The success of this modernisation project is the result of a partnership with Foxboro and Invensys that began seven years ago," said Mr Luiz Renato Figueiredo, Aracruz engineering manager.
"During this period, we have worked together to continuously fine-tune the manner in which we plan and execute system modifications and improvements.
With each new project, we have set new records of accomplishment".
This record-setting automation upgrade was performed using Foxboro's unique system migration approach.
This approach utilises special input/output (I/O) modules that are functionally identical to ordinary I/A Series modules, but are re-packaged to plug right into the existing Fisher Provox (or other vendors) I/O racks.
These I/O modules enable the physical switchover to be accomplished without moving any field wiring, thus dramatically minimising production downtime.
Prior to shutting down the existing Fiberline B evaporation unit control system on the scheduled system switchover date, the joint Aracruz and Invensys migration team prepared all I/A Series screens, defined the control strategies, converted the database and thoroughly tested all elements.
The same migration approach was previously utilised to replace the Fisher Provox boiler controls on Fiberline B.
According to Mr Floreal Puig, Aracruz recovery and utility manager, based on the success of these two upgrades, the approach is being considered for other mill areas as well.
Fiberlines A and C at the Espirito Santo State mill are already under I/A Series control.
