I am drawing a complete blank this morning looking for a unicorn.
I would like to install a device at a remote site that will gather the data points from that site and my polling system would get its info from that.
When the radio goes down or looses comm because a truck parked in front of it again... it would continue to poll for and store the timestamped data points.
When comms are restored the data points would them be recaptured into the motherships Historian in the proper space in the timeline.
I can't envision how this would even be possible but I'm sure it is. I believe this was the point of the DNP protocol which I have never used either.
If this was Ethernet connected I imagine a local historian would be the option but otherwise... not sure.
Any thoughts on a more generic solution? Even manf names to start with to get a feel on how its done would be helpful.
