PROFIBUS and PROFInet technology and standardization activity

This paper outlines an effective approach for the standard development in industrial digital communications. The paper mainly focuses on the differences between Manufacturing Automation Protocol (MAP) and PROFIBUS, but the detailed technical specifications for both the buses are not described. This paper points out the some of the important items which include: (1) easy to develop and introduce, (2) factory layer concept, and (3) smooth connection to the existing technology. The author believes that a practical solution is more easily accepted by the market than a technology oriented one.
