Hi,

do we get the data in event stream (with source: Tag Event) from edge data sync? In particular, in case there was a disconnect and the buffered data are synced evenuelly.

Bests,  
André

Can you better explain the scenario / architecture where these two technologies work together?

Hi @Kevin.Herron

sure, I will try it.

If we have an architecture like this. Will those technologies, Edge Sync with S&F and Event Streams at the Central Ignition Gateway, work together?

**Concrete:**

1. Edge collects data from the PLC
2. Data sync to the central gateway [**Is this a source for the event stream?**]
3. Edge and central are disconnected
4. Edge buffers the data
5. Connection is restored
6. Edge syncs the buffered data to the central gateway [**Is this a source for the event stream?**]

I'll check with somebody to make sure, but I don't think these work together. Edge sync and S&F are for things backfilling history, they're not a real time tag value source.
