Logical Networks Quiz

What is one of the key differences between industrial and I.T communication?

Industrial communication involves a larger set of communication devices (correct)
I.T communication has more data exchange involving multiple entities
I.T communication is more robust in harsh environments
Industrial communication has longer data blocks

What is the purpose of Industrial Ethernet?

To ensure unlimited data exchange between industrial entities
To standardize the use of Ethernet in industrial and office communication
To provide deterministic communication between machine controllers, actuators, and sensors (correct)
To prioritize data transmission over standard Ethernet networks

Which approach to deliver determinism in Industrial Ethernet uses standard Ethernet with TCP/IP and a built-in application layer mechanism?

Ethernet/IP
Standard-Software Standard-Ethernet (correct)
Open-Software Standard-Ethernet
Open-Software Modified-Ethernet
