I use toggle the bit in discret alarm tag (Operator_Message) . Need make invisible status alarm in journal and change message (Full_Message_Text) before toggle bit. 

Setting for discrete alarms:

 Alarm text:

User <Tag : 15, Currenr_User>: <Tag : 200, Full_Message_Text>

 Script:

 SmartTags("Full_Message_Text") = MSG_Text&" "&SmartTags("Device_Name")

SW_MSG = SmartTags("Operator_Message")

If SW_MSG Then

ResetBitInTag SW_MSG, N_SetBit

SmartTags("Operator_Message") = SW_MSG

Else

SetBitInTag SW_MSG, N_SetBit

SmartTags("Operator_Message") = SW_MSG

End If
