Total Number of Packets Sent (Response)
The total number of packets sent by the EtherNet/IP Unit or built-in EtherNet/IP port is returned.
Total Number of Errors Sent (Response)
The total number of packet errors detected while the EtherNet/IP Unit or built-in EtherNet/IP port was sending
is returned.
Total Number of Send Collisions (Response)
Returns the number of packets damaged by 16 collisions with data from other nodes during EtherNet/IP Unit or
built-in EtherNet/IP port transmissions.
Precautions
Counting of the total number of packets received, total number of receive errors, total number of packets sent,
total number of errors sent, and total number of send collisions is discontinued when the counted value
reaches the maximum value.
