Towards Adding Safety and Security Properties to the Industry 4.0 Asset Administration Shell

Industry 4.0 (I4.0) intends to make manufacturing agile, more efficient, and more customer-oriented. Considerable efforts have been made to enhance the safety and security aspects of I4.0 systems. However, the lack of a standard model has prevented the convergence toward safety and security. Plattform Industrie 4.0 has introduced the Asset Administration Shell (AAS) with the Reference Architectural Model Industry (RAMI 4.0) to integrate assets into the world of information. This paper draws the potential capabilities of AAS in bringing safety and security to I4.0 systems. For this goal, a safety and security model is proposed based on RAMI 4.0 to be used as a reference for developing the AAS model. A level control system is used as an illustrative example of an Industrial Control System (ICS) to demonstrate how to respond to I4.0 safety and security challenges using the AAS model.
