The Tap solution supports three models for providing Human Machine Interfaces (HMI) as mobile apps.
Static Single Target model for a manufacturer creating an HMI app for a single type of appliance (ex. an app for a model of clothes washers).
Static Multi Target model for a manufacturer creating a common HMI app for several types of appliances (ex. the same app provides HMI for a clothes washer, dish washer, oven, etc.).
These "static" models are for appliances that have pre-defined use. HMIs are integrated in the apps and the apps are delivered as installation packages.
Dynamic Multi Target model - the manufacturer creates an app environment that can be updated dynamically with HMI for programmable multi-purpose equipment (ex. an industrial Programable Logic Controller).
In this case, HMI are created at the time of their installation, when the equipment is purposed. HMIs are then delivered dynamically to users via the manufacturer's app and the mobile's network connection when users connect to equipment.
