Niagara Sensor Status Bar

Scada Alarm


The Sensor Status Bar Widget is a simple status indicator. The value is represented by a horizontal color bar progressing from min to max over a specified range. It retrieves data from a numeric point or numeric writable and updates in real-time. The facets are automatically retrieved when the point has been resolved. Before you start, copy the sensorStatusBar-ux.jar file to your modules directory. Restart the station and Workbench.


1. Copy the sensorStatusBar-ux.jar file to your modules directory.
2. Open the module from your palette file.
3. Drag and drop the widget from the palette onto your px view.

Widget Properties


The widget has a number of configurable properties that can be used to modify look, feel, and functionality. Change the properties as required:

Widget Ord Binding (wbViewBinding):

This can be an absolute ord, e.g. station:|slot:/Drivers/NiagaraNetwork/AHU6
relativized ORD e.g. slot:AHU6

Min/Max Range Acceptable values are 0-n positive values. The shaded area will calculate the correct area to shade in based on min/max and actual values. Numbers are rounded off to the nearest whole number.

Background Color The default is transparent. If your px/html page has a different color, set this property to match it.

Using in your HTML Page

You can now use the widget in your custom html page as long as the html file is in a appropriate station directory.
E.g. C:/../stationName/shared/webfiles/demo1.html

1. Create an html page and place in your station files directory.
2. Create a div element and give it an id so you can inject the widget into this area. E.g.: widget1.
3. Add the following scripts before the closing head tag or the closing body tag. E.g.:

<script type="text/javascript">

    var require = {
        paths: {
            //pointing nmodule at /module is a Niagara convention, allowing us to
            //refer to module resources without having RequireJS get hung up on
            //the use of absolute paths everywhere.

Widgets and drivers must be licensed with us. Licenses are bound to the stations host Id. You will be provided access to the Software and Licensing Portal where you can manage your own licenses. Here you can add, update, or delete licenses as needed.

There are few ways to get a license file:

1. Add our licensing module to your station services. This module automatically retrieves the license from our servers and saves it to your stations shared folder directory.

2. Alternatively, Login to the Software and Licensing Portal (link provided in Order Confirmation) and add your host id's as needed. Copy the license file to the stations shared directory.

Finally, make sure the station user has access to WLicenseService in the user management and category service section.
