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): Communication Interfaces (HW and SW) Configuration and device parameterization Support for device registration
• Strong background in PROFIBUS and FOUNDATIONTM Fieldbus Creator of the first PROFIBUS FMS implementation Unique set of FF stacks, like Link Master, Field Device, HSE, Linking Device

Profibus PA & Foundation Fieldbus
Softing Field Device based on Mitsubishi M16C62 and Find 1+ or SPC 4-2 Protocol stack for PROFIBUS PA and FOUNDATIONTM Fieldbus Identical Function Block interface Almost 50% of all FF-registered field devices are equipped with Softing BFD protocol stack

Intrinsically Safe Network DilemmaExisting IS Networks:
– ControlNet
– Foundation Fieldbus
– Profibus PA
– HARTThe IS Networks are:
– Too big– Too complicated – Too expensive!
CAN Based Network:– Preferred Solution
– BUT, Not Intrinsically Safe
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!

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

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
FOUNDATIONTM 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

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

The Idea: OEM package
• Processor moduleincluding 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 packageTraining, etc.
• GSD file
• Device certification

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

The Idea: Steps to do
• Flexible specification As much input as possible Mechanical dimensions IS issues
• Re-design of existing module to meet NeSSI requirements
Number of I/O channels Onboard A/D converter Form factor/Connectors
• Generic signal converter• To cover our NRE´s: initial PO (DOE project?)• Time frame
