  23. PROFINET for Clock-Synchronised Applications (1) • RT applications are not generally synchronous: • Different asynchronous cycles • Applications, data transfers and field devices each operate on their own processing cycles • Cycle times are very imprecise • Jitter is of the order of the cycle times Communication cycle Application cycle Device cycle Field device Field device Drive Controller Pharmatex 2008

  24. PROFINET for Clock-Synchronised Applications (2) • Based on clock-synchronized data transfer • Application, data transfers and device cyclesare synchronous • Cycle times < 1ms with jitter precision < 1µs • Typical field of application is motion control Communication cycle Application cycle Device cycle Field device Field device Drive Controller Pharmatex 2008

  29. A B Isochronous Real Time (IRT) with Route Planning • If the performance is to be optimized even further: • Objective:x trains should travel from “A” to “B” in the shortest possible time • Ancillary constraints:Prescribed railroad network,Time spent standing in stations, Journey time between stations. • Objective achieved by planning:i.e. by optimizing both the route and the departure times • Scheduling the communications • Specifying transfer times and transfer routes Optimizing the available bandwidth Pharmatex 2008

  31. IRT in Standard PLC – Why? • Uses the same network for process data and standard Ethernet data (e.g. VoIP) without this affecting the process data •  Under IRT process data is transferred with its own interval • Machine and plant structure with numerous line-switched subscribers and short refresh times •  IRT devices guarantee shorter throughput times (30%) • PLC synchronous initiates drive functions (e.g. positioning) for a number of motion controllers • PLC as sync master provides deterministic cyclical communication for PROFINET with IRT Pharmatex 2008

  32. The PROFINET IO device model • A PROFINET device has a modular structure with “slots“ that contain “subslots“. • A “slot/subslot“ can contain a module/submodule • The subslot is the addressable element. • Slot 0 is representative of the device, • Subslot 0 is representative for the module.
