1. Importing the device description IODD

Importing the device description simplifies the integration of the IO-Link devices. The individual process data are broken down, enabling simple parameterization of the sensor. The IODD only needs to be imported during the initial commissioning of a new IO-Link device. The import is port-independent. Proceed as follows to import the IODD:

1. Importing the device description IODD 1:Fig.21: Import of the IODD device description via “IODD Finder”

Integrating the IODD via the “IODD Finder”

1. Click on the “Device Catalog” button in the “IO-Link” tab (see figure above (1)).
The “Device Management” window will open.
2. Search for the desired IO-Link sensor/device by choosing the search field and entering the search term in the search mask (see figure above (3)).
3. Select the desired IO-Link sensor/device. Move the mouse pointer over the figure of the desired IO-Link sensor/device. A blue download icon appears, see figure above (4).
4. After clicking on the download icon, the .xml file of the selected IO-Link sensor/device is imported and stored in the following folder:
- for TwinCAT 2.x: \TwinCAT\IO\IOLink
- for TwinCAT 3.x: \TwinCAT\3.X\Config\IO\IOLink
5. When moving the mouse pointer over the IO-Link sensor/device, a green icon now indicates (see the following figure) that the .xml file already exists.
6. The imported device descriptions are listed in the “Local” tab in the tree structure, sorted by vendor.

Button "Import Devicedescription“

1. Press the “Import Devicedescription” button in the “IO-Link” tab
2. Select the .xml file of the desired sensor.
3. After pressing the Open button, the imported files are stored in the following folder:
- for TwinCAT 2.x: \TwinCAT\IO\IOLink
- for TwinCAT 3.x: \TwinCAT\3.X\Config\IO\IOLink.
The imported device descriptions are listed in a tree structure in the “Catalog” field, sorted by vendor.

No manual copying of the XML files

Do not copy the files directly into the folder; read them in via Import Devicedescription instead! Important checks will otherwise be bypassed!
