In modern industrial automation, the need for efficient and intuitive control logic programming has become increasingly crucial. Traditional text-based programming languages, while powerful, can be complex and challenging to visualize, especially for complex control strategies. This creates a significant problem for automation engineers, leading to longer development times, increased debugging efforts, and reduced overall productivity. To address these challenges, Siemens has introduced the Continuous Function Chart (CFC) language in their TIA Portal software, providing a graphical programming approach that allows engineers to design control logic visually using interconnected function blocks.
