Sensor/Actuator Manager Candidates CPAC/NeSSI Workshop May 5, 2005, Seattle,WA by Softing North America Ken Hoover

Softing -- a recognized world leader in the key technologies of industrial communications Fieldbus Products OPC Technology Based on Open Standards Ethernet Analysis Tools

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 FF-H1 H1 Devices Modbus/TCP FG-100 FF/M Control HMI / SCADA

SAM Solutions via Fieldbus/Ethernet Gateways Modbus/TCP Example Output global control registers H1 ch1 80 AO H1 ch1 80 DO H1 ch2 80 AO H1 ch2 80 DO H1 ch3 80 AO H1 ch3 80 DO H1 ch4 80 AO H1 ch4 80 DO compact output image Input status information H1 ch1 80 AI H1 ch1 80 DI H1 ch2 80 AI H1 ch2 80 DI H1 ch3 80 AI H1 ch3 80 DI H1 ch4 80 AI H1 ch4 80 DI compact input image Modbus View Modbus/TCP Client e.g. PLC Ethernet 4 FF H1 Lines FF H1 View FF H1 Devices Gateway Modbus Registers Built-in Multi I/O Blocks Gateway maps FF-H1 Process Data to Local Memory (Modbus Registers)

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) Fieldbus Sensor/Actuators Ethernet TCP/IP Gateway with embedded OPC Server Control HMI / SCADA

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.
