FDT frame applications and DTMs are programs, which only need to be reinstalled in a new the new system environment, just as system software. (Office 97 still runs under Windows XP)

Both, Device DTMs and Communication DTMs are not comparable to the device drivers of the operating system. Thus, there is no dependence on the hardware installed in a computer.

Only the computer hardware responsible for communication with the field devices, e.g. PROFIBUS card, requires, under certain circumstances, new system drivers. New DTMs are not required. Communication DTMs use system drivers, but are not concerned itself, comparable to OPC communication drivers.

There will be still access to all data bases and device configurations. The storage of data and device configurations is done in FDT Frame Application.
