• Index
This object specifies the index number of the object held by the IO-Link device.
• Subindex
This object specifies the subindex number of the object held by the IO-Link device.
• Length
This object specifies the size of the data to be written when writing. The unit is bytes.
• Data
This object specifies the data to be written when writing.
• Error Code
This object indicates the error code when the status value of subindex 02 hex is 04 hex or 05 hex.
The meanings of the error codes are as follows. When the value of status is 02 hex, the meaning is
normal end, and the value of error code is 0000 hex.

• Timeout
This object is the time that the IO-Link Master Unit monitors a response from an IO-Link device. The
unit is ms. The monitoring time is an integer number of seconds obtained by rounding up the less-
than-second part (lower 3 digits in decimal notation) of the set value to the nearest second. When
0000 hex is specified, the monitoring time is 2 s.
• Sequence No
This object specifies the sequence number of the message to be sent.
