EtherNet/IP Diagnostics
ISDU Requests When Port
Offline
Displays the number of ISDU requests received over EtherNet/IP when the
IO-Link port was offline. This can occur when:
• The IO-Link port is initializing, such as after start-up.
• There is no IO-Link device attached to the port.
• The IO-Link device is not responding.
• Communication to the IO-Link device has been lost.
Valid ISDU Responses
From Port
Displays the number of valid ISDU response messages returned from the IO-
Link port interface and available to the PLC(s). The response messages
contain results to the ISDU command(s) received in the request message.
ISDU Response Timeouts
Displays the number of ISDU requests that did not receive a response within
the configured ISDU Response Timeout.
Unexpected ISDU
Responses
Displays the number of unexpected ISDU responses.
Unexpected responses may occur when an ISDU response is received after
the ISDU request has timed out. This typically requires setting the ISDU
Response Timeout to a longer value.
ISDU Read Commands Displays the number of ISDU read commands received over EtherNet/IP.
Maximum ISDU Request
Msg Response Time
Displays the maximum time period required to process all commands within
an ISDU request message. The response is not available until all ISDU
command(s) contained in the request have been processed.
Average ISDU Request
Msg Response Time
Displays the average time period required to process the ISDU request
message(s). The response is not available until all ISDU command(s)
contained in the request have been processed.
Minimum ISDU Request
Msg Response Time
Displays the minimum time period required to process all commands within
an ISDU request message. The response is not available until all ISDU
command(s) contained in the request have been processed.
ISDU Write Commands Displays the number of ISDU write commands received over EtherNet/IP.
ISDU NOP Commands
Displays the number of ISDU NOP (no operation) commands received over
EtherNet/IP.
