How does Labview support redundancy?

[weatherhound]

I have a control system and Labview will act as the means of control/monitoring. However, I want to have a primary and secondary computer with duplicate system setups. How does Labview support this type of redundancy such that if the primary goes down, the secondary will take control seamlessly.

Hi,

LabVIEW has many capabilities that can be combined to create a very robust redundant system. Some of these features include the following:

• Archiving databases periodically
  
• Monitoring a process on a remote machine
  
• Executing an application on the backup when the primary has failed

The most straight forward method of implementing the monitoing is to use discrete memory tags to create a heartbeat. When the heartbeat on the Primary machine has stopped, the backup should take over and begin execution.

If you have specific questions about how to implement this, feel free to call support by going to www.ni.com/ask.
