Cyber-Physical Systems (CPS), even with benefits in terms of automation and management in Industry 4.0, present challenges that need to be explored - such as the lack of standardization in the definition of characteristics and requirements for their development. We believe that the definition of a specific requirements catalog for these systems is one of the relevant steps to ensure greater adequacy and quality of industrial practices. Thus, this project aims to propose a catalog of requirements for CPS in the context of Industry 4.0, serving as a guide for the development and improvement of these systems. The catalog was developed based on the execution of a systematic review and on the experience of experts (including evaluation and elicitation experiences for CPS requirements). The purpose of this catalog is to help users, managers or directors, to compare, select, and improve their understanding of this type of system - being compatible with the productive, sociocultural, functional, and economic criteria, ensuring higher quality and standardization for Industry 4.0 practices.
