4. Review the HMI/MSG Connected (Class 3) table to monitor Class 3

messaging statistics.

5. Review the I/O and Prod/Cons Packets Per Second (EtherNet/IP Port -

Class 1) table to monitor Class 1 messaging statistics.

If the number of
Sent Packets Count
is this percentage of
the module’s
capacity

Then

0…80%

No action is required.
Important: This is the optimal rate.

Greater than 80%

Monitor other IO and HMI PPS to determine how application can be changed to
avoid performance concerns.
Important: Your EtherNet/IP communication module can function at the 100%
packets sent per second rate, but at or near this rate, you run the risk of
performance problems.

If the number of
Sent is this
percentage of the
module’s capacity

Then

0…80%

No action is required.
Important: This is the optimal rate.

Greater than 80%

Take steps to reduce the number of Class 1 packets sent per second.

Important: Your EtherNet/IP communication module can function at the 100%
