Redundancy in NI-DAQ OPC Servers

[zalmay]

I have three computers namely A,B and C. On A and B NI-DAQ OPC server is configured.
I am accessing A & B from Cmputer C which have Labview DSC module( OPC Client).
Now I want to exercise Redundancy such as if Computer A get failed then DSC module on

Computer C switch over to B.
Also how data on both NI-DAQ OPC Server can be kept synchronized.

Any help,KB,Presentation,tutorial  in this Regard will be highly appretiated.
Deep Regards

Hi Zalmay,

Which version of DSC are you currently running?  To implement the redundancy you described I believe you could implement software to monitor the error of  the tags you are reading and switch to which computer you are reading from.  Also check out the following link on how to Synchronize Time Settings with DSC.

How Do I Synchronize Time Settings on Networked Computers when using Lookout or LabVIEW Datalogging and Supervisory Control Module?
