The client’s sales team and their trainers needed an online solution of their HMI simulators, and they should be easily accessible from any place and time.

Solution proposal

SafetyHeads team prepared a solution that works on Azure, Angular 11 and .NET Core5. Our proposed system supports all mainstream browsers like Chrome, Safari, FireFox etc on laptops as well as on tablets. Offline mode is handled by dedicated service worker responsible for loading needed data to the local environment (browser). That approach secures application availability and proper devices simulation without internet connection (this option works after pre-load of whole page data only).


The team developed HMI web simulators that are available offline and online. The architecture allows easily to create other devices if needed.


1. Analize structure and content of the devices and prepare backlog.

2.Prepare architecture.

3.Deliver best solution to the Client.


The web Click Dummies are statically preconfigured to a specific (maximum) system scheme, so that all customer relevant HMI features can be shown. 13 devices with various configuration were developed.
