In the very first issue of PROFINEWS North American Edition way back in March 2005, there was a PROFINET quiz.  Taking a few questions from there and adding some more allows us to present the 2016 PROFINET Quiz:

(click “TRUE” or “FALSE” below to see if you are correct)

1. PROFINET is PROFIBUS on Ethernet. TRUE or FALSE

2. PROFINET fully complies with standard Ethernet IEEE 802.3. TRUE or FALSE

3. PROFINET can use an unmanaged Ethernet switch. TRUE or FALSE

4. PROFINET is proprietary. TRUE or FALSE
