Implementing an AAS for a Siemens motor control system

This master thesis covers the implementation of an Asset Administration Shell (AAS) for a Siemens Motor Control System (SMCS). The implementation consists of creating the AAS, then establishing a real time communication between the AAS and SMCS. The AAS is the digital twin for Industry 4.0 systems, and structures related data elements into sets called submodels. This thesis will provide an overview of the establishing of basic monitoring and control of a set of Siemens hardware using the TIA Portal, which was installed on a local PC, that was connected to the hardware by a PROFINET protocol. A larger focus will be on the creation of the AAS for the hardware, as well as establishing communication between the AAS and SMCS. The relevant hardware is a Siemens motor, a Siemens inverter and a Siemens PLC. The creation of AAS was done with the AAS Package Explorer and AAS server from the admin-shell-io github. Basic control of the hardware was created with the TIA Portal. Communication between the TIA Portal and the AAS was facilitated with the open source tool NodeRED. The work covered by this thesis has deployed the AAS as a fog-based, centralized AAS. This thesis discusses these, and other deployment options, and weighs up these options in regards to the scale of the system. The result entailed being able to monitor and control the hardware by using the AAS Package Explorer and Blazor interface.
