Build a Marquee

Reference Materials: All About Marquees.

We call them Marquees, but you may know them as Andon or Visual Display Management systems. Whatever you call them, we have provided a rather simple method of providing a set of rotating dashboards to TV screens located throughout your plants.

As part of the default install, you should have received a project called kanoaMarquee. This project contains nothing more than a page through which we can pass parameters back to the marqueeDisplay view to indicate where this marquee is to be displayed. We could have added this page to the kanoaMES project, but its likely that you'll want to configure the project to not have security and to automatically update whenever changes are made in the designer.

The page url consists of /marquee/display/:siteCode/:location/:screenName which allows us to send the site, location at the site and tv screen identifiers.

For a giant TV mounted say in your Texas site, in the breakroom, you would create a startup shortcut on the TV embedded PC to open a browser or a Perspective workstation to

http://demo.kanoa.ai/data/perspective/client/kanoaMarquee/marquee/display/Texas/Break%20Room/TV4

You'll need to change the demo.kanoa.ai to point to your gateway.

The Marquee Display Editor

Whenever a TV or device opens a browser to the gateway marquee display, that device is registered as a marquee display device. In the Marquee Editor screen, you can now configure which marquee is to be displayed on that device and what theme to set. All changes are immediately updated on the device. All configuration for your TVs and devices throughout your plant can be configured centrally from the kanoaMES application with no need to change anything on the device itself.

If no marquees are configured for the device, the default dashboard will be displayed. If you only want to show a static display on a tv, simply create a marquee with a single dashboard.

The Marquee Editor

A marquee consists of an ordered list of dashboards with how long they should be displayed for.

It really is as simple of that. Create your widgets, create your dashboards, create your marquees and point your tvs to the kanoaMarquee project.

From Marquees →

A marquee puts key production information on shared screens without anyone having to interact with the application. In this lesson you create a marquee, add dashboards with durations and sort order, preview it, and assign it to a display.

Create a marquee

1. Navigate to Dashboards → Marquee Editor.
2. Click the plus button. A new marquee is created with a default name.
3. Double-click the name to rename it, for example Machine Analytics, and press Enter to confirm.

Expand the marquee using the arrow next to its name. The marquee starts empty.

4. Click the plus button inside the marquee.
5. Select System Dashboard\Asset Overview.
6. Set the duration to 30 seconds.
7. Save it.
8. Click the plus button inside the marquee again.
9. Select Downtime Dashboards\OEE and Top Downtimes (the dashboard you built in the previous lesson).
10. Set the duration to 30 seconds.
11. Save it.

Click Preview Selected Marquee. The marquee opens in a new tab so you can confirm that dashboards appear in the expected order, durations feel reasonable, the layout works on a large display, and the content is readable without interaction.

TV Displays

The second part of the marquee system is Displays. A display represents a specific screen, TV, or viewing station that opens a marquee URL. Once a TV has been setup to launch a client, which marquee is displayed, for how long and how it looks can all be managed from the KanoaMES application.

Add a Display

1. Go to the Displays tab.
2. Click the + button to add a new display and enter the following values.

Site Code	Location	Screen Name
philly	breakroom	tv1

3. Click `Ok'. This will open a new tab displaying 'No Marquee'. This is because we haven't configured what is to be shown on this display.
4. Switch back to the KanoaMES browser tab. On the Displays tab of the Marquee Editor, select the Machine Analytics marquee to be displayed on this tv.
5. Switch back to the TV display browser tab. You should see that it is now cycling through the Machine Analytics Marquee.

Avoid interactive selectors

Selector widgets for asset, date range, area, or time scope are useful on normal dashboards, but marquee displays are passive — a TV display should not require anyone to interact with it. For marquee dashboards, use hardcoded asset paths, hardcoded or default time ranges, dashboard/widget parameters, and a preconfigured display scope instead of asset selectors, date range selectors, or other interactive controls.
