Editing General Information for an IDAS

To edit general information

1. In the Operations Control Management Console tree, expand a server group, and then expand a server.

2. Expand Configuration Editor, expand System Configuration, and then expand Data Acquisition.

3. Right-click the name of the IDAS to edit, and then click Properties. The Properties dialog box appears.

4. Click the General tab.

   

5. To change the name of the computer on which the IDAS runs, click Modify and then type the new name in the IDAS Node box. If you are creating a new IDAS definition or modifying an existing one, make sure that the IDAS software is installed on the target computer.

   Note: If the target IDAS node is also a Historian node, it does not work as a remote IDAS. Choose a node that has the IDAS software installed, but without the Historian Server software installed.

6. Specify a failover option:

   • To disable failover or store-and-forward, select No Failover or Store/Forward.

   • To specify a backup IDAS, select Failover Node.

     In the adjacent box, type the name of the computer on which an optional, redundant IDAS runs. You must use the fully qualified name of the computer. You could also use the IP address. This should be set to an empty string if no redundant IDAS is specified. Make sure that the IDAS software is installed on the target failover computer. If the failure of the primary IDAS is detected by the system, the failover IDAS is automatically started. The failover IDAS is shut down after the primary IDAS is back online.

   • To enable store-and-forward, select Store/Forward Path.

     Type the path for the IDAS data buffer on the local hard drive of the IDAS computer. The path should be absolute (for example, C:\IDASBuffer). Data is written to this path until the minimum threshold for the buffer is reached. Remote buffer paths are not supported.

     Note: Be sure the value for Store/Forward Path is correct and accessible. If not, the store-and-forward functionality will fail.

7. Click OK.
