Compatibility
One of the historical problems with computer-based systems has been
the lack of compatibility among the various manufacturers. This con-
dition is closely related to the long-term marketing benefit of having
a proprietary (incompatible) system. Hardware parts of the systems
are very similar and often interchangeable, but software is not. Gen-
erally, software protocol varies from system to system, with little or
no compatibility. Thus additions to the original system usually must
be made by the original supplier.
The present-day buzzword is
interoperability.
This relates to the
ability of the elements of the control system to work together. This
