  1. SP1486E PROFIBUS and RS485 Applications

  2. What is PROFIBUS? • Industrial communications network • The network is a bi-directional, multidrop, serial-bus, communications network used to link isolated field devices, such as controllers, transducers, actuators and sensors • Created in 1989 in Germany by a consortium of factory automation suppliers. Originally developed for discrete manufacturing, it has expanded into process automation and enterprise-wide applications. • World most popular fieldbus in manufacturing control • 20 Million installed nodes • 40% market share Worldwide • 20% market share North American • Awarded GB/T (China’s highest National Std.) in Nov. 2006 • Binding Std. applies to entire industry and not sector specific Company Confidential

  3. Comparison of PROFIBUS and RS485 PROFIBUS is SUPERSET of RS485 Company Confidential

  4. SP1486E – RS485 PROFIBUS • 20Mbpsdataratewithlowskews • Enhanceddriveoutput,VODof2.7Vtypicalinto54Ω • 1/8thload,upto256devicesperbus • HarshIndustrial/FactoryEnvironments • EnhancedFailsafeforopen,shortedorterminatedinputs • ±15kVESDprotection • Hot-swapprotected • Drivershort-circuitandthermalprotection • Verylowpower • 300μAtypical • 1μAshutdown Company Confidential

  5. 15kV ESD protection Robust for harsh environments Enhanced Failsafe Rx default to fail-safe state if open, short or floating Standard failsafe is only if Rx is open 1/8th Unit Load High input impedance 256 transceiver can share bus Low load = more noise margin Thermal Shutdown Prevents thermal overload caused by bus contention Hot-Swap protection Keeps driver and receiver inactive until power stabilizes Prevents false signals during power-on or hot-plug Wide temperature range -40 to +85ºC Industrial -40 to +125ºC Extended PROFIBUS ready High output driver (2.1V min) Fast 20Mbps rate, low skew Enhanced RS-485 Features Company Confidential

  6. PROFIBUS Target Applications • Manufacturing Automation • Car manufacturing • Bottling systems • Storage systems • Building Automation • Heating, air-conditioning (HVAC) • Networked Security Systems • Process Automation • Purification plants • Chemical and petrochemical plants • Paper and textile industries • Power industry and power distribution • Power plants • Switchgear Waste Water Purification Car Manufacturing Breweries Chemical Production Pipelines Building Automation Food Production Bottling Plants Company Confidential
