ISDU Parameters

ISDU Parameters

To add new ISDU (Indexed Service Data Unit) parameter press “Add” button at the bottom of ISDU group box.

 

 

Then input its index, subindex, byte sequence value (2-symbol hex values separated by “:”), set read/write permission and press ok.

 

 

After successfully adding new ISDU parameter you can see it in the ISDUindex/subindex tree structure.

 

 

To remove an ISDU parameter, select it in the ISDU tree and press Removebutton.

All ISDU parameters must have a unique index and a unique subindex within a given index. Subindices can only go in consecutive order from 0 to some value less than or equal 0xFF without missing values.

You can change a value of an ISDU parameter (also during active IO-Link communication). To do it press edit button, change byte sequence value and press ok. You can also set a “Set to device” option and a changed value will be also transferred to iqInterface if it is connected to iqTool.

 

 


If some ISDU parameters have been read or written from master side during an active IO-Link communication you can see detailed descriptions of these actions in the log text box. To see changed values in the “ISDU” tree press “Upload” button.
