By now it is a well understood fact that Industrial Ethernet is becoming the dominant technology within factory automation for a variety of reasons, but what does not get quite the same attention is the implementation of this communication technology in vendor systems.

This white paper looks at Industrial Ethernet implementation options from the point of view of the factory automation vendor developing slave systems, such as I/O modules and drives.
