IO-Link Diagnostics
This is the actual, or current, cycle time of the IO-Link connection to the device.
This is the minimum, or fastest, cycle time supported by the connected IO-Link
device.
Configured in the Configuration | IO-Link page, this is the minimum cycle time
the IO-Link Master will allow the port to operate at. The Actual Cycle Time,
which is negotiated between the IO-Link Master and the device, will be at least
as long as the greater of the Configured Minimum Cycle Time and the Device
Minimum Cycle Time.
Displays whether the IO-Link device on a port supports the data storage
feature. Not all IO-Link devices support the data storage feature.
Displays whether a port is configured to automatically upload data from the IO-
Link device or download data from the IO-Link Master to the IO-Link device.
Disabled displays if automatic upload or download are not enabled.
The current status of the auxiliary bit as received on DI (Pin 2 on the MD 748I-
11-42/L5-2222) of the IO-Link port.
The supported Device PDI Data Length, in bytes, as stored in ISDU Index 0.
Current status of PDI data as received from the IO-Link device.
The last Rx PDI data as received from the IO-Link device.
The supported Device PDO Data Length, in bytes, as stored in ISDU Index 0.
Status of PDO data being received from controller(s).
The last Tx PDO data.
The time since the last port initialization.
The number of process data errors the port received.
The total number of events that were received on this port.
Up to the first, or oldest, three events that were received on this port.
Up to the last, or most recent, three events that were received on this port.
The number of read ISDU command attempts.
The number of read ISDU command errors.
The number of write ISDU command attempts.
The number of write ISDU command errors.
