IO-Link Port Diagnostics
The following table provides information about the IO-Link Diagnostics page.
IO-Link Diagnostics
Port Mode
Displays the active device mode:
•
Reset = The port is configured to disable all functionality.
•
IO-Link = The port is configured to IO-Link mode.
•
Digital In = The port is configured to operate as a digital input.
•
Digital Out = The port is configured to operate as a digital output.
Port Status
Displays the port status:
•
Inactive = The port is in active state. Typically, this indicates that the
device is either not attached or not detected.
•
Initializing = The port is in the process of initializing.
•
Operational = The port is operational and, if in IO-Link mode,
communications to the IO-Link device has been established.
•
PDI Valid = The PDI data is now valid.
•
Fault = The port has detected a fault and is unable to re-establish
communications.
Device Vendor Name
Displays the Device Vendor Name as stored in ISDU Index 16.
Device Product Name
The Device Product Name as stored in ISDU Index 18.
Device Serial Number
The Device Serial Number as stored in ISDU Index 21.
Device Hardware

Lost PDO Controller(s)
Errors
The number of times that the PDO controller(s) were present and then lost
connection.
PDO Data Valid
Status of PDO data being received from controller(s).
Device PDI Data Length
The supported Device PDI Data Length, in bytes, as stored in ISDU Index 0.
PDI Data Valid
Current status of PDI data as received from the IO-Link device.
Last Tx PDO Data

Time Since Initialization
The time since the last port initialization.
Lost Communication
Count
The number of times that communication has been lost to the IO-Link device.
Initialization Attempts
The number of times the IO-Link port was initialized.
Initialization Errors
The number of port initialization errors that occurred.
Process Data Errors
The number of process data errors the port received.
Process Data Retries
The number of process data retries the port performed.
Internal Communication
Errors
The number of IO-Link Master internal communication errors that occurred on
this port.
Device Communication
Errors
The number of device specific communication errors that occurred.
