Buffered Report IEC61850

Buffered Report IEC61850

Hi,
i configured Bufferd report in Siemens Siprotech 5(850 server) devices and established connection with zenon.
we started testing buffer report in following ways.
1. i removed all/both fiber from the siprotec device(iec61850 server)
2. initiated some signals while the connection is away from zenon 850 client.
3. re-established the connection.

i received the initiated signals. but the issue here is, i received not only the signals which i initiated when connection is away, but also all the variables which already we have tested while connection was available are thrown to the 850 client from the server. is there any option to stop the signal to report again which are already initiated and tested when the connection is live?
summary:
already reported signals should not report again when the connection is re-established.

Thankyou
