Panel with multiple devices

This project provides an example of organising data transfer between an Engee model running in slow motion and a dashboard with multiple instruments.

Illustration of how the example works

The collaboration between the model and the dashboard is shown in the video:

The dashboard can be opened in a separate window or embedded within an interactive script; all interactive elements will function, allowing you to visualise the output data and work with the model in real time.

The model starts in ‘Simulation speed control’ mode.

The simulation runs un inf; therefore, the model can only be stopped by the user.

Run an example

To run the example, open and run the model multiple_dashboard_model.engee, execute the following cell:

# Launch the server with the dashboard
app = engee.genie.start("$(@__DIR__)/app.jl", log_file="$(@__DIR__)/log.txt");
display("text/html", """<iframe src="$(string(app.url))" width="650" height="320" style="border: none;"></iframe>""";)

# Get a launch link in a separate window
# display("text/html", """<a href="$(string(app.url))" target="_blank" rel="noopener noreferrer">Open in a separate window</a>""")

To stop the server for debugging purposes:

# engee.genie.stop("$(@__DIR__)/app.jl");

In case of problems

Given that the UDP protocol is used for communication and services communicate via localhost, communication between the dashboard and the model should be very reliable and very fast.

If you experience slowdowns or missing values, the first step is to close the model and reopen it.

Conclusion

The project presented here allows you to derive several values from the model and track their cumulative trends across various indicators.
