Industrial Graphic Server Configuration

The Industrial Graphic Server is installed whenever the InTouch run-time component is installed on a node, and lets users view InTouch HMI applications in a web browser. There are two configuration items for the Industrial Graphic Server:

• Client Settings: This sets how frequently the Web Client refreshes graphics and alarms.

• Authentication Settings: This establishes the credentials that the Web Client will use for connecting to the web server.

  Note: If a System Management Server is configured, the InTouch Web Client will use the security certificate and utilize the HTTPS protocol for secure communications. See Configuring the System Management Server for additional information.

To configure Client Settings

1. Under Graphic Refresh Rate, set the screen refresh interval. This determines how frequently the web browser will query the web server for graphic data. A longer interval reduces network traffic and may be needed for very low-bandwidth networks or intermittent connections.

   • Default: 1000 ms (1 second)

   • Minimum: 250 ms

   • Maximum: 60000 ms (60 seconds)

   Note: The Graphic Refresh Rate cannot be less than the Alarm Refresh Rate. If you lengthen the Graphic Refresh Rate, the Alarm Refresh Rate will automatically synchronize with the Graphic Refresh Rate.

2. Under Alarm Refresh Rate, set the alarm refresh interval. This determines how frequently the web browser will query the web server for alarm data. By default, the Alarm Refresh Rate is the same as the Graphic Refresh rate. You can make the refresh interval longer for alarms than for graphics, but the Alarm Refresh Rate cannot be shorter than the Graphic Refresh Rate. A longer interval may be needed for very low-bandwidth networks or intermittent connections.

   • Default: 1000 ms (1 second)

   • Minimum: Graphic Refresh Rate

   • Maximum: 60000 ms (60 seconds)

To configure Authentication Settings

3. In the Configurator, select Authentication Settings. There are two options:

   • Windows Authentication (default). Skip to step 3 if you are using Windows Authentication.

   • User Authentication. User Authentication lets you configure the Web Client to use Single Sign-On using the AVEVA Identity Manager. The System Management Server must be configured before selecting this option, and is used as the AVEVA Identity Manager.

4. User Authentication configuration (optional): To allow access outside the plant network, enter the Secure Gateway URL, which is a secure reverse proxy server installed in the DMZ.

5. Press the Configure button.

6. Select the next item in the left pane that requires configuration. When all required items have been configured, press the Close button to complete installation. See System Restart after Configuration.
