Access Active and Archived Messages

In the previous steps, we learned how HELIO displays messages as a dialog and how to introduce a global message indicator in the header of our HMI.

But how can operators view the entire collection of all active and archived messages? And how can they get there from any page page within our HMI as quickly as possible?

We'll get to the bottom of these questions in this next step. And you may already know the answer: HELIO has got a page for that!

  1. Add the Message Page

Displaying a list of active and archived messages is actually quite easy in HELIO, since there is a ready-made page for it: the Message Page, which already contains the right tools to browse these messages and is fully connected to the Messaging Storage.

  • Make sure to reset all the triggers you defined in any previous steps, so no more messages will be active.
  • Add a Message Page to your HMI.

Your page should look like this:

←→
  1. Open the Page as an Overlay

Messages are really important to operators, so it's crucial they're very easy to reach. One of the most widespread ways to achieve this is to add a cell to your header that allows operators to open the message page from any other page within your HMI.

Sound good? Then let's make it happen!

Then your HMI should now be looking something like this:

←→
  1. Optional: Hide the Message Page from Main Navigation

This is an optional step, as in some cases it may still be useful to to make this page available from the main navigation as well. But in most cases it is not necessary to show the page in the main navigation as it might confuse the users.

Click on the Message Page and locate the Main Navigation property group. Choose the Hide Page option.

Have Fun With Messages!

All right, everyone, this is it! We've been working towards this moment for a reason. This is when we get to see all the configured elements in action, interacting and simulating messages:

Mission accomplished!

You went through all the steps to get a full-featured messaging system with a built-in message archive in your HMI.

  • That's pretty much it for Messaging! Now go ahead and create some helpful messages on your own.
