In the construction industry, so-called site information systems are responsible for consistent end-to-end data utilization by connecting relevant stakeholders, which shall increase productivity and sustainability. This paper continues the work on OPC Unified Architecture (OPC UA) data models for mobile machinery and integrates a fault management system. The information model comprises two use cases, precisely machine supervision and machine maintenance. To demonstrate the functionality of the proposed solution, a Software-in-the-Loop Simulation including implemented OPC UA server and clients has been executed. The communication via OPC UA meets the identified requirements of the use cases.
