Hello Abhijit; Isochronous mode was integrated as part of Profibus-DPV2, and allows very close synchronisation of DP-slaves to the DP-master; it is designed for motion control applications. Encoders anddrivesin particular support this version of Profibus, as does Simotion Scout (with a D445 controller, for example). See the following thread for a discussion on DPV2, especially the links provided by our friend Deepak: /tf/WW/en/Posts/21536 In the Softing pdf you will find this definition: Isochronous ModeThe isochronous mode permits fast and deterministic data exchange due to clock synchronization within the bus system. A cyclic and equidistant clock pulse is transferred from the master to all bus stations.Master and slaves can be synchronized to this signal with a precision of < 1μs for all applications. Hope this helps, Daniel Chartier |

Hello ABHIJIT PUNE you may also find the Simatic Isochrone Mode Function manualto be a good yarn (it contains advise on possible applications as well as how to implement/configure it). I hope this helps |
