Progress and Developments in Network Solutions for NeSSI Generation II CPAC May 2005 John Mosher – Honeywell Sensing & Control The Network “Rail” Enables Information Communications Interface “Rail” The Area Between the Enabling “Rails” is Where Sensor and Instrument Vendors Add Value and Commercialize Intellectual Property. Physical Interface “Rail” – ANSI/SP76 NeSSI-Net • NeSSI Generation II Network Requirements: - Intrinsically Safe - Multi-variable Capability - Configuration Storage and Update Capability - Diagnostic Capability - Connectivity to Sensor Actuator Manager (SAM) - Fault Tolerance - Protocol administered independently (not by NeSSI/CPAC) - Open System - World-wide acceptance - Petrochemical market acceptance - Key customer acceptance The Network Enables Information and Uptime Foundation Fieldbus •Foundation Fieldbus Chosen for Generation II/III - Proposed, discussed and accepted at CPAC Fall Meeting - Meets all criteria of requirements - Minor engineering work to shrink network interface - Press Release Issued at Foundation Fieldbus General Assembly •The Fieldbus Foundation: - Offered to help with Specification Definition - Will coordinate resources with NeSSI product vendors - Offered Technical Assistance in Implementing FF - Understands Vision for MicroAnalytical Platform - Free Device Conformance Testing Foundation Fieldbus Value: • FF delivers benefits today - Wiring and cabinet savings - Asset management for lower maintenance and fewer incidents - Faster startup, commissioning, maintenance • Fieldbus supports a rich set of capabilities - Control on the wire (the only protocol that has it) - Automatic Addressing - Automatic Configuration via Electronic Data Descriptions - Automatic Replacement Device Configuration - Built-in Alarming - Function Blocks for Simple Device Management - Seamless Data Transfer with FF HSE (High Speed Ethernet) Foundation Fieldbus Users • • • • • • • • • • • • • BASF BP Bristol Myers Squibb ChevronTexaco ConocoPhillips CPC Distileria Serralles Gaz de France NGT Petroquimica União Polioles S.A.
