IO-Link diagnostics
On the electronic modules for ID key-operated switches for IO-Link, it is possible to carry out
diagnostics 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:

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 con-
nected actuator is too high.
• Check the electrical cable con-
nection 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 inva-
lid.
• Reset the electronic module to
the delivery state and reconfigure
the electronic module.
• Return the device to the manufac-
turer.
Individually encodable ID key cannot
be saved:
Key list is full
50 individually encodable keys have al-
ready been saved, and the available
memory range is full.
• Check the data in data sets 81
and 82 (memory of the individual-
ly encodable ID keys (1-30) - data
set (index) 81, and memory of the
individually encodable ID keys
(31-50) - data set (index) 82)
• Delete the no longer used individ-
ually encodable ID keys from the
memory.
Individually encodable ID key cannot
be saved:
invalid key
• No valid individually encodable ID key
inserted.
• The inserted individually encodable
ID key is defective.
• Use an individually encodable
ID key if, for example, a colored
ID key has been inserted.
• Use another individually en-
codable ID key since the inserted
ID key could be defective.
• Check that the ID key has been
inserted as far as it will go.
