Hello,
Regarding implementing redundancy in your DSC application, Steven's answer to your earlier post (monitor the error state of the tags/variables and swapping servers on errors) was a good one. Have you followed up with him for more information? You can find the previous post
here.
NI doesn't produce or officially endorse redundancy management software packages, although it is also possible to set up redundant servers using Lookout.
I'm curious about your application - since you're publishing over DAQ OPC, I presume you wish to share measurement hardware. Do you have a completely redundant set of hardware, or is this software redundancy only?
Cheers,
Matt Pollock
