Retrieving data via PI OPC HDA from data source that swotches between two servers.

Hi,

 

Does anyone know how to configure the PI OPC HDA Interface to automatically switch between two identical Data Sources servers (Main/Backup) if one of them goes down?

 

I can see that the 'Failover' facility can be used for a configuration involving 1 data source and 2 PI server destinations, but I need to set up a configuration the other way round with changing data source servers going to 1 fixed PI server database.

 

Is this at all possible and can it be done by configuring the Interface tool ?

 

Any help would be greatly appreciated.

 

Pete
