EtherNet/IP Diagnostics
The following table provides information about the EtherNet/IP Diagnostics page.
EtherNet/IP Diagnostics
Active Session Count
The number of active Ethernet/IP sessions. A session can:
• Support both Class 1 I/O and Class 3 Messages
• Can be initiated by either the PLC or the IO-Link Master
• Can be terminated by either the PLC or the IO-Link Master
Active Connections The current number of active connections (both Class 1 and 3).
Total Connections
Established
The total number of connections that have been established.
Connection Timeouts The number of connections that have closed due to timing out.
Connections Closed The number connections that have closed due to a standard processes.
Class 3 Messages/
Responses Received The number of Class 3 messages and responses received from the PLC or
PLCs.
Broadcast Messages
Received
The number of broadcast messages received from PLC or PLCs.
Class 3 Messages/
Responses Transmitted
The number of Class 3 messages and responses sent to the PLC or PLCs.
Class 1 Output Updates
(From PLC)
The number of Class 1 output data updates received from the PLC or PLCs.
Class 1 Output Data
Changes (From PLC)
The number of changes in Class 1 output data received from the PLC.
Class 1 Input Data
Updates (To PLC)
The number of Class 1 input data updates sent to the PLC or PLCs.
Client Object Requests The number of Class 3 requests to the IO-Link Master vendor specific objects.
Good Responses from PLC The number of good responses from messages sent to PLC or PLCs.
Bad Responses from PLC
Displays the number of bad responses from messages sent to the PLC or
PLCs. Bad responses are typically returned for such errors as:
• Incorrect tag or file names
• Incorrect tag or file data types
• Incorrect tag or file data sizes
• PLC is overloaded and cannot handle the amount of Ethernet traffic
• PLC malfunction
No Responses from PLC
Displays the number of no responses from messages sent to the PLC or PLCs.
No responses are typically returned for such errors as:
• Incorrect IP address
• Incorrect PLC configuration
• PLC malfunction
• PLC is overloaded and cannot handle the amount of Ethernet traffic
Invalid Network Paths
Displays the number of network path errors on messages sent to the PLC or
PLCs. These are typically caused by incorrect IP address settings.
Pending Request Limit
Reached
Displays the number of pending request limit errors. These errors occur when
the PLC is sending a continuous stream of messages to the IO-Link Master
faster than the IO-Link Master can process them.
Unexpected Events
Displays the number of unexpected event errors. Unexpected event errors
occur when the IO-Link Master receives an unexpected message from the
PLC such as an unexpected response or unknown message.
