The strategic initiative Industry 4.0 implies integration of Cyber-Physical Production Systems (CPPS), Internet of Things (IoT) and cloud computing, leading to what is called “smart factory”. The lack of theoretical foundation and methodologies for development of CPPS creates barriers that may hamper the adoption, commercialization, and market success of the new CPPS applications. Standardization and digitalization are at the heart of the methodologies for developing intelligent cyber-physical production systems. OPC UA is the only recommended communication standard within the RAMI reference architecture. Here comes the main purpose of the paper to analyze OPC UA in respect to the information model creation and measures to ensure security of applications. An important place in the paper is devoted to the specification of standardized information models of other organizations, such as those of the ISA-95 (IEC-62264).
