Abstract: This article explores the application of Siemens' LCCF library functions in industrial automation
projects. The LCCF library provides a software level solution that replaces traditional hardware protocol
gateways with library functions to enable data exchange between different communication protocols.
This article introduces the classification and functions of Siemens library functions, and elaborates on the
main components of the LCCF library and its advantages in protocol conversion, including simplifying the
configuration process, enhancing system compatibility, and reducing technical barriers. Through specific
application examples, the implementation method of LCCF library in communication between SIMATIC
controller and Rockwell and Mitsubishi controllers is demonstrated. In addition, the article also compared and
analyzed two Siemens communication libraries, LCom and LCCF, pointing out their similarities and differences.
