IOC to Expand I/A Series Digital Automation Systems Using Latest Foxboro Mesh Network Technology at Canada's Largest Mineral Processing Plant.

FOXBORO, Mass. -- Project will connect multiple generations of systems, putting entire Iron Ore Company of Canada plant under I/A Series control

Invensys Process Systems has been selected by Iron Ore Company of Canada (IOC) to implement a new mesh network-based Foxboro automation system for beneficiation processes at IOC's Labrador City iron ore concentrator. The plant is located near the western boundary of Labrador, Province of Newfoundland and Labrador, Canada. Connecting with several existing Foxboro systems, the new control system, when completed, will put all plant processes under I/A Series control.

The IOC Labrador City concentrator complex is Canada's largest such operation, with an annual concentrator production capacity of about 16 million tons. Approximately 75 percent of this capacity is processed into pellets on-site, and the balance is shipped directly to sinter feed customers.

Invensys will implement the latest I/A Series Version 8.X hardware and software, which will replace outdated equipment used to control the magnetite recovery and spiral processes. It will integrate with existing I/A Series systems used for controlling the grinding area and hematite plant, and the expanded system will have approximately 10,000 I/O points connecting to the network.

The integrated network will leverage IOC's investment in existing controls, and will allow IOC to combine all the process areas into a single process control system with a common operator interface for all plant units. The network infrastructure also has the capacity to integrate controls that support planned future production expansions by IOC.

The contract also includes services from Invensys Systems Canada, covering engineering services, factory acceptance testing, training services, and field services to support the I/A Series implementation. The Foxboro control automation project will be implemented in stages, with completion planned for the fall of 2006.
