I am having ABB REF615 & RED615 IEDs in each of my station with GE RX3i RTU. I have downloaded the variables from IEDs to RTU (both Pos.stVal and Pos.t). Then in RTU I move the Pos.stVal to a register in RTU which finally reaches SCADA. My issue is that the timestamp of the signal does not match with IED timestamp. SCADA is showing the timestamp done at RTU when the signal reaches RTU. How can I make use of Pos.t and use it as the signal's timestamp.
