Upload flag on 
the IO-Link 
device 
To enable the upload flag of an IO-Link device,  
the value 0x05 must be entered in the index 0x02, subindex 0. 
(Parameterization, see IO-Link Service Data on the next page) 
 
The upload flag is needed to overwrite already saved data in the parameter server with new 
parameter data of the same IO-Link device 
This function is a supplement to an output configuration of the respective port pin. 
For each port pin, a safe status can be predefined which is to be assumed in the event of  
a loss of bus communication. 
 
The following values are possible for the settings: 
0x00: 0 
0x01: 1 
0x02: last state 
5.6.  IO-Link 
parameterization 
Via object 0x4000 (IO-Link Service Data Ch. X), IO-Link ISDU parameters can be read or 
written from the IO-Link device. To do this, the corresponding index and subindex must be 
entered. In addition, the corresponding length and the data must still be entered when writing. 
Via the control object, the read or write task is then started. In the Object status, the result is 
then displayed. 
Values for the Control: 
  0x00: No action 
  0x02: Write 
  0x03: Read 
Values for the Status: 
  0x00: No activity 
  0x01: Active / Busy 
  0x02: Access 
  0x04: Error 
  0xFF: Failure
