4. Armin Tesch, Softing North America, Inc. © SOFTING 2004 Softing Background (2) Products and Services for „Industrial Communication“ and „Industrial Control“ Support of vendor-independent international standards Fieldbus systems, Ethernet protocols and related technologies Products: PC interfaces, diagnostic tools, OPC toolkits, Gateways Services: custom tailored projects (examples): è Communication Interfaces (HW and SW) è Configuration and device parameterization è Support for device registration Strong background in PROFIBUS and FOUNDATION TM Fieldbus è Creator of the first PROFIBUS FMS implementation è Unique set of FF stacks, like Link Master, Field Device, HSE, Linking Device

5. Armin Tesch, Softing North America, Inc. © SOFTING 2004 Profibus PA & Foundation Fieldbus  Softing Field Device based on Mitsubishi M16C62 and Find 1+ or SPC 4-2  Protocol stack for PROFIBUS PA and FOUNDATION TM Fieldbus  Identical Function Block interface  Almost 50% of all FF-registered field devices are equipped with Softing BFD protocol stack ABB, S, USA, I, D, UK Bürkert, D Endress & Hauser-Group Invensys/Foxboro, D, Nl, USA Anderson Instrument, USA Flowserve/Limitorque, USA Honeywell, USA Krohne, D Pepperl & Fuchs, D Samson, D Toshiba, Japan Yokogawa, Japan Unique Solution for PA and FF

6. Basic Requirements (1) A Dilemma Softing can help solve the Dilemma: Small hardware platform Protocols designed for this kind of application Modular firmware available Proven technology We can help solve this! Armin Tesch, Softing North America, Inc.

7. © SOFTING 2004 Basic Requirements (2) Small form factor (shall fit into 1.5“ tube) Cost-effective Intrinsically safe Flexible and user-independent design concept Easy-to-build application software Bus-powered

8. Armin Tesch, Softing North America, Inc. © SOFTING 2004 PROFIBUS PA vs. FOUNDATION Fieldbus Identical physical layer (IEC 61158-2) Requires sophisticated hardware PROFIBUS Simple Master-Slave communication Idea: DP for intrinsically safe applications Easy to configure Worldwide acceptance FOUNDATION TM Fieldbus „Distributed Control System“ Does not need a Master Highly complex configuration Sophisticated Device Description Language Time consuming Device registration process Similar Function Block Model

9. Armin Tesch, Softing North America, Inc. © SOFTING 2004 Proof of Concept Demo Application here at CPAC Existing HW module fits in 1.5“ tube Sample application built in less than three days Via segment coupler to RS485 (regular DP) PROFIBUS Master (PC-card) OPC server to feed data into Visual Basic application

10. Armin Tesch, Softing North America, Inc. © SOFTING 2004 The Idea: OEM package Processor module including PA stack and FB`s Signal converter (if at all) off-the-shelf or custom built Transducer Blocks (SW) ready-to-use, based on templates or custom built Support package Training, etc. GSD file Device certification Analog Sensor Analog Sensor switch MA U SPC 4-2 M16C Position sensor I 2 C SDRAM PA NeSSI device Fieldbus interface EEPROM A/D Mitsubishi M16C Find 1+ SPC 4.2 PA Slave Stack Function Block Shell Transducer Block Sensor / Actor AIPIDAO Micro controller Field bus ASICs PROFIBUS PA Network

11. Armin Tesch, Softing North America, Inc. © SOFTING 2004 The Idea: Benefits Significant quantities keep production costs low HW design doesn´t require any changes Easy-to-build transducer blocks Limited NRE costs One-stop-shop approach (HW, SW, training, & engineering) Technology originally designed for this kind of communication (proven!) No major technical challenges Significant savings in time and money

12. Armin Tesch, Softing North America, Inc. © SOFTING 2004 The Idea: Steps to do Flexible specification è As much input as possible è Mechanical dimensions è IS issues Re-design of existing module to meet NeSSI requirements è Number of I/O channels è Onboard A/D converter è Form factor/Connectors Generic signal converter To cover our NRE´s: initial PO (DOE project?) Time frame
