Transcript The NeSSI™-bus & DOE Update

Progress and Developments
in Network Solutions for
NeSSI Generation II
CPAC May 2005

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)
