DIN EN IEC 63303 VDE 0810-303:2025-06

This standard defines general structures and functions of HMI systems and a life cycle example for HMI systems and specifies requirements and recommendations for activities in each stage of the life cycle including designing, using and maintaining the HMI system. It also provides recommendations for functions and performance of HMI systems. The recommendations in this document are applicable to any controlled process using an HMI to interface to a control system, including but not limited to continuous, batch, and discrete processes. There can be differences in implementation to meet the specific needs based on the controlled process type. For Safety Instrumented Systems related applications refer to IEC 61511.
