Rockwell Automation Publication 1734-UM020B-EN-E - August 2019
Configure the POINT I/O 4 Channel IO-Link Master as IO-Link Master Using the Studio 5000 Add-on Profile
c. Device ID – Enter the device ID of the IO-Link device.
This field is disabled if Electronic Keying is Disabled
d. Input length – Enter the input length in bytes of the IO-Link device.
Valid range is 0...32. The value is obtained from the device vendor.
e. Output length – Enter the output length in bytes of the IO-Link
device. Valid range is 0...32. The value is obtained from the device
vendor.
6. Click OK. A pop-up dialog box displays.
7. Click Yes.
8. Click Apply to save the changes.
9. Click OK.
Use message instructions to the IO-Link Device Parameter Object to read or
change configuration parameters for IO-Link devices with IODD Basic or
Generic integration.
About the IO-Link Device Parameter Object
IO-Link device configuration parameters include multiple sets of index/subindex
pairs, a length, and a data value that is sent to the Master Module through
instances of the IO-Link Device Parameter Object.
The IO-Link Device Parameter Object provides a mechanism for a CIP™ client
to access parameters within an IO-Link device. Within this class, the instance
number maps to an IO-Link index value.
The details of each index and subindex depend entirely on the IO-Link device
and are described in the IO-Link Data Description (IODD) XML file for that
device or data sheet provided by the device vendor.
Create a Message Instruction for the IO-Link Device
Before you proceed, take note of the following:
• For IODD Advanced integration, when you change IO-Link device
parameters by message instruction, a correlation check is performed when
the Add-on Profile is launched. You can then select to use either the device
or controller parameter values.
• Messages to/from IO-Link parameters are raw IO-Link data format. As
such, unsigned, packed bits and endian/byte swapping issue need to be
handled accordingly. Ladders have to be created to enable byte swapping of
values from the MSG instruction.
• See the Studio 5000 help for more information on how to create message
instructions.
