These events are not part of the DQMH default features and have to be added to every HSE DQMH module.

'Module Is Ready'

Use the Module Is Ready broadcast to indicate that a module is ready to be used in the application

'System Message'

Sends a HSE-generic broadcast message, consisting of an Identifier, a variant Payload and Source information.
  • Provides a generic way of broadcasting information
  • Allows for dynamic registering and triggering of broadcast events

  • string Identifier
  • variant Payload
  • enum Source Type (module, application, network)
    • the typedef can be found in hse-libraries/hse-dqmh.lvlib/Templates and Controls/System Message Source.ctl
  • string Source Name (Module Name)
    • for clones, the Clone ID is appended to the Module Name
Singleton

Message Types

Ready for Display

Lets the UI Manager know that a module identified by <b>Main VI Reference</b> wants to be displayed in the content subpanel.

Optional: “Title” specifies the string to be displayed in the Title indicator of Layout VI

Optional: “Target SP Name” defines the subpanel in which to display the module.

Add to Run-Time Menu

Remove from Run-Time Menu

Removed from Subpanel

Sent from UI Manager's “Load Module into Subpanel” MHL case, lets the application know that a module has been removed from the subpanel it was shown in.

Startup Completed

Lets the UI Manager know that the startup phase of the whole application (ie anything that should happen before the splash screen is hidden and the front panel of UI Manager is shown) has completed.

UI Manager will send the “Startup Completed Received” broadcast, which notifies the startup.vi to wrap up startup phase.

Update Splash Screen Message

Updates the Splash Screen of the application with Message and Percentage during the startup phase (i.e. before the “System Message - Startup Completed” has been sent.

UI Manager will send the “Update Splash Screen Message Received” broadcast, which notifies the startup.vi to update the controls on the Splash Screen.

Note: Use percentages between 61% and 99%.
