It also plays a critical role in establishing decision-mak- ing systems and enabling high-quality, cost-efficient, and productive digital twin implementa- tions. This study presents a methodological approach to developing communication interface specifications between Manufacturing Execution Systems (MES) and shop-floor equipment, which is a core component of digital factory systems. The research systematically analyzes the principles of data generation and acquisition, along with the technical considerations for inter- face design. For each phase of interface configuration, the required types and characteristics of data are identified. By applying the proposed methodology, newly constructed digital factories can establish well-structured equipment communication specifications aligned with operational goals, thereby enhancing system reliability and efficiency. kor 한국CDE학회 디지털 팩토리 시스템을 위한 공정 설비들의 올바른 Command 및 Event 구성 방안 Article 403 3 393 한국CDE학회 논문집 30 한국CDE학회 논문집, Vol.30 No.3, pp.393-403 10.7315/CDE.2025.393 Digital factory Digital twin Equipment interface specification Command Event Right data Article
