Configure data acquisition redundancy

Data acquisition redundancy objects involve two DIObjects and the RedundantDIObject. In data acquisition redundancy, you must configure all three components:

• Primary DIObject data source

• Backup DIObject data source

• Redundant DIObject data source

Because data acquisition redundant components are essentially standalone objects, all valid operations that apply to any other ApplicationObjects apply to the three objects.

All IDE commands, Galaxy Dump and Load functions, and import and export operations are valid on the two DIObject data sources and the RedundantDIObject.

See the online help associated with each DIObject for help in configuring its Object Editor. Also see the help associated with the RedundantDIObject.

Before you can deploy the RedundantDIObject, you must configure at least one scan group. Also, configure only scan, block read, and block write groups shared by the Primary and Backup DIObjects in the RedundantDIObject.

To configure the Redundant DIObject

1. On the General tab of the Object Editor, set the Primary DI Source and Backup DI Source.

2. Set up the common scan groups.

3. Set up the common block read and block write groups on the tabs of the Object Editor.
