IO-Link diagnostics
Electronic modules for IO-Link can be diagnosed via IO-Link. Short-circuit is signaled via the
diagnostics mechanism of IO-Link. With all further diagnostics messages, the corresponding
bit is set in data set (index) 92 - diagnostics.
The table below provides information on possible causes and remedial measures:
Table 12- 9 Possible causes and remedial measures
Diagnostics and messages
Possible cause
Possible remedial measures
Short-circuit
•
The electrical cable connection on at
least one of the digital outputs has been
short-circuited.
•
The connected actuator is defective.
The current consumption of the
connected actuator is too high.
•
Check the electrical cable
connection of the digital outputs.
•
Check the current consumption of
the connected actuator.
•
Use a new actuator.
Self-test error / internal error
•
Fault in internal test.
•
The data saved in the device are
invalid.
•
Reset the electronic module to
the delivery state and reconfigure
the electronic module.
•
Return the device to the
manufacturer.
The table below indicates how the manufacturer-specific diagnostics are reported:

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", you can determine via the group error (GE) 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 "Diagnostics - data set (index) 92 (Page 594)").
