4D Read_Index Reads an entire index (all parameters within an index) from
the IO-Link device (uses subindex 0)
4E Write_Index Writes an entire index (all parameters within an index) to
the IO-Link device (uses subindex 0).
Class 3A3
Instance the device-specific parameter index value as specified by the device vendor.
See
Locate the Parameter Index or Subindex Value in the IODD File on page 50 for more information.
Attribute 0
Source Element one of the following according to the service code.
4B (read subindex) source_array where source element data type is SINT[2].
In this case SINT[0] is subindex as provided by the Device vendor, SINT[1] is the
channel number from where the data has to be read.
The channel value ranges from 0 to 3. The value must be in hex.
See
Read Subindex Request Parameters on page 49 for more information.
4C (write subindex) a local source tag that contains data that is to be sent with the service. The
source element will have a byte for the subindex number, a byte for the channel
number, followed by the bytes of data that need to be written.
See
Write Subindex Request Parameters on page 49 for more information.
4D (read index) source_array where source element data type is SINT.
In this case, the SINT is the channel number from where the data has to be read.
The channel value ranges from 0 to 3. The value must be in hex.
See
Read Index Request Parameters on page 49 for more information.
4E (write index) a local source tag that contains data that is to be sent with the service. The
source element will have a byte for the index number, a byte for the channel
number, followed by the bytes of data that need to be written.
