Hello IETV_Anka; Standard Profibus telegrams do not support timestamp transfer over the bus. And most standard (DPV0 and DPV1) slaves are not "synchronized" over Profibus, to my knowledge, unless they use Profibus IRT (isochronous realtime, for motion applications). Looking at the VPA_3CG (Profibus interface for the Easergy P3 protection relay) manual, there seems to be no integration of a timestamp in the data exchanges at the slave level. https://greentech-electronics.com/wp-content/uploads/2018/12/VVPA3CG_EN_M_C004.pdf If you would like to do the timestamping in the master, look at our friend Fafner's suggestion in the following post, it might be one way of adding the timestamp to your received signalls when you detect a change. Hope this helps, Daniel Chartier |
