Abstract: The NAMUR automation pyramid is the current state of the art in the process control industry. The pyramid is a monolithic structure with information flowing either in top-down or bottom-up directions. Introducing new technologies into this structure would imply modifying or replacing existing equipment and the control software. NE 175 opens up this closed structure with a new open architecture (NOA) to provide access to external interfaces without changing the existing structure safely, securely and reliably. In continuation of the NOA, the NE 178 presents an architecture for the verification of the request concept (VOR) to allow plantspecific M+O applications to make requests for a change in functioning of the plant bypassing the strong hierarchy of the pyramid. This paper attempts to model the actors involved in this concept and their interactions using the Pro-Active AAS concept, it introduces a new interaction protocol and demonstrates the concept using the single water tank case study.
