没有区别的，从V16开始，start Drive不再提供Drivelib库文件，而是以选件包里面FB的方式提供。

drivelib库： https://support.industry.siemens.com/cs/document/109475044/sinamics-communication-blocks-drivelib-for-reading-and-writing-drive-data-within-tia-portal-context?dti=0&dl=en&lc=zh-CN

第一句话有说，原文Here you can find the DriveLib for reading and writing data from and to the SINAMICS S/G converter systems within SIMATIC S7-300/400/1200/1500 at TIA Portal. Note: As from Startdrive V16, the DriveLib library is no longer supplied with Startdrive. As from STEP7 V15.1, these blocks are also provided as instructions.
