Hello, I'm afraid S7 PLCs don't use this protocol for time synchronization (haven't found in product support). Maybe you can use the time receiver with this capability in your OS server and then use a "Siemens standard way" for time synchronization for the PLC. More information about the IRIG you can find here: http://en.wikipedia.org/wiki/Inter-range_instrumentation_group_time_codes I don't think it would be possible to develop the Phase-locked loopfor the evaluation of IRIG in the user programm, at least it won't have the sufficient accuracy then. Regards Sydney addition: you can find some information about IRIG time synchronization module (with SICLOCK TS)for the OS station in this document: http://support.automation.siemens.com/WW/view/en/36195862 |
