Update your settings

Dear Experts,
I was using Alarm 7Pbt for buffering of events in case of communication failure. But i am stuck in between as i am unable to get the original time stamp in the buffered events in case of communication failure, i.e if the communication is there between PLC and SCADA. And when communication between SCADA and PLC is healthy i am getting the signal with correct time stamp which i have tested by changing the module time and the SCADA server time.
So i would like to know how can i get the buffered events with original time stamp. and also i would like to know when we say communication failure does it mean communication between PLC and SCADA.
Also i have one more query i had tested the buffering by deactivating the SCADA to simulate communication failure is the right way to test the communication failure if it is not so please guide me in the right direction.
And once i activate the SCADA system i use to get the buffered Events but with SCADA server time and all are having the same time stamped vales
Hope you will enlighten me ASAP as this is very critical for energization of one of the Substation.
