Web HMI Dashboard Deployment

Default installation – No web server required

Once you have configured the Web HMI Registration host and port within the steps defined in Getting Started, you can now access the Web HMI Dashboard from your browser.
Open a browser to the Web HMI Dashboard at the following address:


For example, if you are on the same machine as the OAS Service installation, you are not using SSL, and you are using the default port, the URL will be:


By default, the Web HMI Dashboard will run in Demo Mode which will do the following:

  • All logins no matter the credentials, will be allowed to log into the application and be provided individual dashboard settings
  • New logins will be pre-populated with demo dashboards

To alter any application configurations, locate the Web HMI Dashboard directory located in the installation directory for Open Automation Software. This is typically:

C:\Program Files\Open Automation Software\OAS

The Dashboard folder is located in the OAS installation directory under /webapps/webhmi.
Note: previous versions of the OAS server located these files within a www directory in the installation directory.

Within this directory, look in the “js” directory and locate the file app_config.js. This is a JSON file containing application settings.

oas_url : optional hard-coded URL of the OAS server location. Omit this setting and the application will assume the server:port used to connect to the app
show_login_url : <true | false> determines if the OAS url can be supplied by the user in the login screen to point the application to a specific OAS service
session_timeout : <integer> number of minutes of inactivity before the user session is ended and the login screen is displayed
demo_mode : <true | false> enables or disables demo mode, enabling logins with any credential and enabling the refresh button to reset all dashboard modifications to the defaults
demo_dashboards : a JSON representation of the demo dashboards pre-populated for new users in demo_mode

Standalone web server deployment

If you choose to host the Web HMI Dashboard on your own web server, simply copy the contents of the www directory (described above) to the web server like any other static files. Be sure to include all files and folders within the www directory.

NOTE: when hosting the Dashboard on a separate server, you must alter the app_config.js setting for oas_url. This must be the server:port of the OAS server hosting the live data. This setting must be in the form:
