Signal Grouping - Time Stamps

Signal Grouping - Time Stamps

Dear Support,
I have five variables from IED ( IEC 61850). If any of these variables is true the result_bool is true and it is  sent via IEC 60870-5-104 to DC. 


Lets say:  if bool3 is true (overcurrent protection triggers) the result_bool is sent via IEC 60870-5-104.
Is the time stamp of result_bool the same time stamp as the bool3 (time stamp from IED)?
Or the time stamp of result_bool is the time stamp from Zenon Logic?

Do I need to use VSIGETTIME and VSISETTIME  to make code for every signal which occurs to pickup time stamp and write it to result_bool?
