How can I log user changes?

Why do the mappings I create have longer names than the existing mappings in the Plastic Application HMI?

The mappings in the Plastic Application project are shortened to improve clarity and avoid potential performance and storage space issues caused by long names. For more information, see Optimizing Mappings in the TwinCAT HMI project.
