In the Reference Architecture Model for Industrie 4.0, the concept of Asset Administration Shell is presented as the corner stone of interoperability. Asset Administration Shell is dened as a digital representation of an asset able to provide information about the asset including documents, properties, parameters, and functionalities, all organized in a consistent way. Information provided by an Asset Administration Shell can be adopted during whole life cycle of a production system, from its development until its disposal. At the lowest level of the hierarchy of a production system, usually automation and control programs are executed by Programmable Logic Controllers, whose programming technology is based on IEC 61131-3 standard. The IEC 61131-3 programs, the Programmable Logic Controllers where they run, and the real plant controlled are closely related. Considering the life cycle of a production system, the description of IEC 61131-3 programs and the relevant relationships with the plant should be clearly dened, leading to several advantages for example regarding the denition of testing plant operations, maintenance operations at run-time and reconguration process of the plant. What is missing for the realization of what said so far is a standard way to realize this description. For this reason, the paper presents an Asset Administration Shell model able to represent IEC 61131-3 programs and the relevant relationships with Programmable Logic Controllers and each device of the controlled plant.
