Technology Expertise

•Industrial Fieldbuses–Protocol stacks–Device development–Diagnostic software–Hardware interfaces

•Ethernet Gateways•OPC (Software Bridges)

SAM Solution via Fieldbus/Ethernet Gateways• Connect host systems on Ethernet to local fieldbus networks• Support multiple fieldbus channels• Support a variety of industrial fieldbus serial protocols

– FOUNDATION Fieldbus H1– PROFIBUS– CAN/CANopen/DeviceNet

• Can be adapted to industrial Ethernet protocols– FOUNDATION Fieldbus HSE– Modbus/TCP– PROFInet– Ethernet/IP

• Gateways can have embedded Linux operating systems

SAM Solutions via Fieldbus/Ethernet Gateways

• PROFIBUS Example– Gateway “tunnels” data to

Host Systems via Ethernet

– Host Systems must have PROFI awareness

– Sensors are often wired to concentrators

• Remote I/O racks

• PLC’s

• Proprietary controllers

SAM Solutions via Fieldbus/Ethernet Gateways

• FF-HSE Example– Gateway “Links” and maps

data from H1 Devices through to HSE Host systems

– Devices are intelligent, architecture is distributed, requiring no concentrator

– Host Systems must have HSE Support

SAM Solutions via Fieldbus/Ethernet Gateways

• Modbus/TCP Example– Gateway collects data

locally and stores it in local memory

– Host with Modbus/TCP support can send and receive data from gateway

– Host Systems must have Modbus/TCP support

SAM Solutions via Fieldbus/Ethernet Gateways

• Modbus/TCP Example– Gateway managed via

embedded web server

– Comprehensive diagnostics

SAM Solutions via Fieldbus/Ethernet Gateways

• Modbus/TCP Example– Process data available

via web browser

– Resident memory makes data available at any time

SAM Solutions via Fieldbus/Ethernet Gateways

• A hybrid solution may be the best• Uses OPC

– Originally OLE for Process Control– Software bridge technology used in thousands of

applications– Now works with Linux as well as Windows– OPC for Linux allows embedding OPC functionality in

devices (gateways)

• Toolkits are available to customize systems to sensor/actuator manufacturer requirements

SAM Solutions via Fieldbus/Ethernet Gateways

• Hybrid Example via OPC– Gateway collects data

locally and stores it in local memory

– Embedded OPC Server makes data available to any software package or system with OPC Client functionality.

– Host systems without OPC functionality can add it via OPC toolkits

– System can work with any fieldbus technology and leverages standard technologies (Ethernet)

What are we waiting for?

• Not much, really…• Lots of technology available for SAM

functionality.• Customer requirements need to be defined.• Lower cost for NeSSI devices will drive

availability of SAM products.
