Released as a robust update to the V15 generation, it serves as a critical bridge for users transitioning from older platforms (like Step 7 v5.x) to the modern, unified engineering framework.
While it has been succeeded by newer versions (V16, V17, V18, V19), V15.1 remains a highly stable industry standard used by thousands of machine builders and factories worldwide. It offers a unified environment for Controllers, HMI, and Drives, fundamentally changing how automation projects are downloaded, commissioned, and maintained.
