Configure remote history providers

You must specify a name and network location for each remote history provider that you want to use with the InTouch HMI. You can use either a remote InTouch history provider or a remote IndustrialSQL Server history provider.

Note: A remote history provider cannot be configured for an InTouchView application. For more information about the limitations of InTouchView applications, see InTouchView applications.

While the local InTouch application is considered a history provider, you do not need to define it for your application.

If you reference an undefined history provider in an application, WindowViewer ignores the reference and an error message is written to the Logger.

The HistData utility cannot retrieve historical information from a Historian provider.

Configure a history provider

1. Open WindowMaker.

2. On the File menu, select Configure, and then select Distributed Name Manager.

   The Distributed Name Manager configuration screen appears, with separate tabs for the Distributed Alarms and the Distributed History.

3. On the Distributed History tab, select the + icon to add a history provider, or press Alt+A.

   The Add history provider dialog appears.

   

4. In the Provider name box, type the name you want to use for the new historical provider.

   A provider name can be 16 alphanumeric characters or fewer.

5. Configure an InTouch history provider

   1. Select InTouch provider.

   2. In the UNC name box, type the UNC path to the InTouch application directory and then select Add.

      The UNC path format is:

      \\node_name\volume_name\directory\

      If the UNC location is password-protected, you must first establish a node connection using Windows Explorer.

6. Configure an AVEVA history provider

   1. Select Historian.

   2. In the Data source box, type the node name of the server where the Historian Server is installed.

   3. From the Credentials drop-down list, select the credentials for authentication.

   Note: For standalone InTouch applications, the credentials are retrieved from the Application Manager. For managed InTouch applications, the credentials are retrieved from the Credential Manager of the Application Server. For more information, see Work with Credential Manager in AVEVA™ InTouch HMI Application Development.

7. Select Test connection to verify the connection to the Historian Server database. A message appears indicating whether the connection to the database is successful or not.

8. Select Add to close the dialog box.

   The Historian Server node appears in the History Providers list.
