1)
 The manufacturer-specific diagnostic events listed in the table are reported to the IO-Link 
master via the diagnostics mechanism of IO-Link. 
2)
 With the "process image input" (see Chapter "Process image (Page 225)"), you can 
determine via the group error (GE) bit or general warning (GW) bit in the user program 
whether detailed information on diagnostics or messages is available in diagnostic data set 
92. If bit ( = 1 ) is set, you can obtain detailed information on what caused a "group error" by 
reading data set 92. 
3)
 GE = Group error: You can find detailed information in diagnostics data set 92 (see 
Chapter "Data set (index) 92 - diagnostics (Page 282)").
