PlantWeb PlantWeb PlantWeb field-based architecture is an automation solution that delivers
asset management, process control and management execution through three key components:
• Intelligent field devices • Standards & platforms • Integrated modular software
These networked components are linked by open communication standards that include FOUNDATION™ fieldbus at the field level, Ethernet at the plant level, and OPC at the supervisory level.
In such a solution, all components act as nodes on the network, collecting, distributing and using information.
In the simplest interpretation, PlantWeb works like this:• Intelligent field devices gather information • Delta V™ automation system provides easy management • and delivery of the information for process control and management execution
functions • AMS software processes the information to add asset management functionality

Honeywell PlantscapeHoneywell Plantscape Its advanced architecture encompasses a high-performance
controller, advanced engineering tools, and an open control network. PlantScape makes use of the latest technology that includes:
• a powerful Microsoft Windows 2000-based Server with dynamic data caching, alarming, human/machine interface, history collection, and reporting functions;
• HMIWeb™ Technology, providing secure, advanced user interface HMI capabilities based on an open industry standard html file format and Web Browser access;
• a compact Hybrid Controller that provides truly integrated control;• object-oriented tools to quickly and easily build reusable control
strategies;• ControlNet, an open, state-of-the-art producer/consumer control
network;• FOUNDATION Fieldbus, for integration of measurement and control
devices; and• secure Internet Browser based on-line documentation and support.

Invensys (Foxboro)Invensys (Foxboro)I/A Series SystemI/A Series System A hierarchical perspective, ranging from
enterprise-wide information protocols down to the instrument bus.
• Enterprise information: generally Ethernet/ TCP/IP
• Control bus: Ethernet/TCP/IP is now the standard.
• The I/A Series incorporated the first Ethernet control bus (Nodebus – Redundant).
• Redundant fieldbus to remote I/O.• Instrument bus: Intelligent field device
integration (for example, HART, FOUNDATION fieldbus, Profibus, FoxCom). Invensys/Foxboro introduced the first all-digital intelligent instrument bus.

As Ethernet becomes the dominant communications structure, the traditional hierarchical nature of these four layers becomes less important, and we see the overall architecture
flattening.

PCT ObjectivesPCT Objectives
Identify requirements for CORBA-based distributed control systems.
Perform experiments in conditions of systems heterogeneity and legacy integration.
The PCT will be:• Representative of an industrial process plant.• Able to prove different design alternatives to the
normal industrial approach (such as different topologies, integration of heterogeneous devices at the same level,...)
