EtherNet/IP Diagnostics
Unsupported CIP Class
Errors
Displays the number of unsupported CIP class errors.
These errors occur when a message that attempts to access an invalid class is
received by the IO-Link Master.
Unsupported CIP Instance
Errors
Displays the number of unsupported CIP instance errors.
These errors occur when a message that attempts to access an invalid
instance is received by the IO-Link Master.
Unsupported CIP Service
Errors
Displays the number of unsupported CIP service errors. These errors occur
when a message that attempts to access an invalid service is sent to the IO-
Link Master.
Unsupported CIP Attribute
Errors
Displays the number of unsupported CIP request attribute errors. These
errors occur when a message that attempts to access an invalid attribute is
sent to the IO-Link Master.
Unsupported File Errors
Displays the number of messages from SLC/PLC-5/MicroLogix PLCs that
attempt to access an unsupported file address.
System Resource Errors
Displays the number of system resource errors. These errors indicate a
system error on the IO-Link Master such as operating system errors or full
message queues. These errors typically occur when the PLC or PLCs are
sending messages to the IO-Link Master faster than the IO-Link Master can
process them.
First Error String Text description of the first error that occurred.
Last Error String Text description of the last error that occurred.
EtherNet/IP Port Specific Diagnostics
Configuration Errors
Displays the number of improper configuration errors. These errors occur
when the IO-Link Master receives a message that cannot be performed due to
an invalid configuration.
Invalid Data Errors
Displays the number of invalid message data errors. These errors occur when
the IO-Link Master receives a message that cannot be performed due to
invalid data.
Active PDO Controller(s)
Lists the controller interface(s) type, (Class 1 or Class 3), and IP address that
are controlling the PDO data.
PDO Writes to Offline or
Read-Only Ports
Displays the number of PDO write messages that were dropped due to any of
the following:
• The port is configured in IO-Link mode:
- There is no device connected to the port.
- The IO-Link device is off-line.
- The IO-Link device does not support PDO data.
• The PDO Transmit Mode (To PLC) is disabled.
• The port is configured in Digital Input mode.
Undeliverable PDI
Updates (To PLC)
Displays the number of PDI update messages that could not be delivered to
the PLC in the Write-to-Tag/File method. Undeliverable updates may result
when:
The IO-Link Master cannot complete an Ethernet connection to the PLC.
The PDI data is changing faster than the Maximum PLC Update Rate.
ISDU Request Msgs From
PLC(s)
Displays the number of ISDU request messages received from the PLC(s) or
other controllers. These request messages may contain one or multiple ISDU
commands.
ISDU Invalid Requests
Displays the number of ISDU requests received over EtherNet/IP with one or
more invalid commands.
