Describes an Application Program Interface (API) for applications that provide communications between the users' network and IEEE p1451.0. An API is also provided between IEEE p1451.0 and the underlying physical communications layers usually referred to in this standard as IEEE 1451.X. These API definitions are provided for systems that have visible interfaces.
