My apologies if this is an obvious question as I’m still learning this system:
We are building a system which pulls in instrument data wirelessly to a gateway server which then connects to Ignition through OPC-UA. Data is tagged and historized in the normal fashion. The problem we have is that if the wireless network goes down anywhere, tag/historical data flatlines as no change is registered by Ignition.
I believe that I can upgrade our wireless modules to record data locally, with a timestamp. What I would like to do is be able to pull in missed data (either manually or automatically) and then push it into the historian with the correct timestamp. The issue of course is that for this to work, I would have to go “back in time” in order for the data to arrange itself properly. Can anyone provide guidance on how to do this?? Thank you in advance for your advice!
