3. doc.: IEEE 802.15-08/0765r0 Submission November 2008 M. Bahr, Siemens AGSlide 3 Use Cases of Factory Automation automotive – robots – suspension tracks – portable machine tools –milling, turning –robot revolver filling cargo – airport logistics – post packaging industry special engineering conveyor technique

4. doc.: IEEE 802.15-08/0765r0 Submission November 2008 M. Bahr, Siemens AGSlide 4 Requirements for Factory Automation (I) high reliability high determinism –bounded delay / latency very low latency: –transmission of sensor data in  10 ms –short duration between subsequent transmissions very small data –data might be only 1 byte

5. doc.: IEEE 802.15-08/0765r0 Submission November 2008 M. Bahr, Siemens AGSlide 5 Requirements for Factory Automation (II) many sensors per gateway –up to 250 sensors per gateway different traffic patterns –limited traffic: sensors send data only infrequently often event-triggered –heavy traffic: sensors send data (very) frequently often continuous data transmission

6. doc.: IEEE 802.15-08/0765r0 Submission November 2008 M. Bahr, Siemens AGSlide 6 Requirements for Factory Automation (III) star topology –gateway –sensor nodes –temporary management devices minimal overhead in data frames –short header flexible superframe structure roaming between gateways –for instance, for conveyor techniques

7. doc.: IEEE 802.15-08/0765r0 Submission November 2008 M. Bahr, Siemens AGSlide 7 Network Topology star topology gateway devices –sensors: unidirectional data exchange from devices to gateway –actuators: bidirectional data exchange between devices and gateway –management devices (temporary)

8. doc.: IEEE 802.15-08/0765r0 Submission November 2008 M. Bahr, Siemens AGSlide 8 Assumptions assume controlled environment (factory floor) configuration for optimal performance network management and frequency planning for avoidance of co-existence issues
