Couple of things:
1. Please provide mopre info': How are you accessing the Citadel database? Are you using the Historical VIs from DSC palette? Or the HDV in MAX or the HTV in DSC? Are all of these failing? Are the Citadel Services running?
2. You may want to post your query in the Datalogging and Supervisroy Control section of this forum for faster response. They deal with Citadel, DSC, etc. Here's the link:
