  The vision of Industry 4.0 introduces new requirements to Operational
Technology (OT) systems. Solutions for these requirements already exist in the
Information Technology (IT) world, however, due to the different
characteristics of both worlds, these solutions often cannot be directly used
in the world of OT. We therefore propose an Industrial Business Process Twin
(IBPT), allowing to apply methods of one world to another not directly but,
instead, to a representation, that is in bidirectional exchange with the other
world. The proposed IBPT entity acts as an intermediary, decoupling the worlds
of IT and OT, thus allowing for an integration of IT and OT components of
different manufacturers and platforms. Using this approach, we demonstrate the
four essential Industry 4.0 design principles information transparency,
technical assistance, interconnection and decentralized decisions based on the
gamified Industry 4.0 scenario of playing the game of Nine Men's Morris. This
scenario serves well for agent based Artificial Intelligence (AI)-research and
education. We develop an Open Platform Communications Unified Architecture (OPC
UA) information and communication model and then evaluate the IBPT component
with respect to the different views of the Reference Architecture Model
Industry 4.0 (RAMI4.0).
