Problem in time stamping of events

Dear experts,

I am using cpu412-2dp , cp443-5 dp and wincc scada in one of my project. Siprotec relays are connected to cp443-5 dp.All the cpu,scada and relay are time synchronised.Now the problem is events which are time stamped in relay should be directly send it to wincc system.

But currently all the events are time stamped in scada. Is there is any way that all the events which are occuring in relay can be send it to scada system through plc with time stamping information of the relay.

Any special blocks in plc are there to send event information with time stamp coming from field to scada system without changing time stamp.

Please suggest me some solution.
