The idea is, to have a software counterpart of every physical device to provide a simple mode, health and commanding interface. By separating the underlying Communication Interface with DeviceCommunicationIF, a DH can be tested on different hardware. The DH has mechanisms to monitor the communication with the physical device which allow for FDIR reaction. +Device Handlers can be created by overriding `DeviceHandlerBase`.
