This document discusses Siemens' S7-300 automation platform. It provides an overview of the S7 system family including the S7-400, S7-300, and S7-200 ranges. The S7-300 is positioned as a mid to low-end performance range. The document outlines innovations for the S7-300 including increased processing speed, expanded memory and quantitative framework, improved communication performance, and a more compact design. A roadmap is presented showing the planned stages of further S7-300 development through 2003.
