I/O Packets Per Second
I/O Packets Per Second Send (Actual)
Number of Class1 EtherNet/IP packets the system transmitted in the last
second.
I/O Packets Per Second Received
(Actual)
Number of Class1 EtherNet/IP packets the system received in the last
second.
I/O Packets Per Second Total (Actual)
Total number of Class1 EtherNet/IP packets the system transmitted/
received in the last second.
I/O Packets Per Second Rejected
(Actual)
Number of Class1 EtherNet/IP packets the system rejected in the last
second.
I/O Packets Counts
I/O Packets Sent
Cumulative number of Class1 EtherNet/IP packets the system
transmitted.
I/O Packets Received Cumulative number of Class1 EtherNet/IP packets the system received.
I/O Packets Rejected
Cumulative number of Class1 EtherNet/IP packets the system rejected.
These packets were messages received and then rejected because the
connection was closed or there was a duplicate multicast address.
I/O Packets Missed
Cumulative number of Class1 EtherNet/IP packets that were not received
in order.
Each UDP packet has a sequence number and if a packet is missing
(corrupted or dropped), the system recognizes this void upon receipt of
the next packet received. Missed counter increments by the number of
packets missed.
I/O Packets Total
Cumulative number of Class1 EtherNet/IP packets the system
transmitted/received.
The total is the sum of all packets that were sent, received, inhibited, and
rejected.
Application Connections
Type Defines the class of the connection in terms of Class1 or Class3.
Status
Defines the current state of the connection in terms of Active and
Inactive.
UpTime Elapsed time for the connection that has been maintained.
Serial Number Unique identifier for each connection.
O->T Packet Size Size of originator to target packet data in bytes.
T->O Packets Size Size of target to originator packet data in bytes.
Missed Packet Rx Number of packets that are missed by that particular connection.
