25 Memory error Memory or EEPROM I2C error
26 Start-up error Start-up error
27 Diagnostic error This flag is set if the encoder detects a
diagnostic error.
28 Reserved
29 Sanity-check flag This flag is set if the encoder detects a
diagnostic error.
30 Slave sign of life This functionality is active if byte 0 of attribute
106 is set.

Error Code Message Possible Cause
16#0108 Connection-request error
connection type (multi-cast/uni-
cast) not supported.
Check whether the configuration assembly (instance 100 of
the Assembly Object) is activated. If yes, check whether the
configuration data are correctly and fully configured in this
assembly (see Figure xx on page 55).
16#0114 Electronic keying mismatched:
electronic keying product code
and/or vendor ID mismatched.
Check whether the wrong EDS file has been selected (for
example, single-turn instead of multi-turn or vice versa).
16#0127 Connection request error: invalid
output size.
Check whether the correct communication format for the
control system is used. The default value in the control system
is “Data-DINT.” The encoder requires the communication
format: “Input Data-DINT.”
16#0204 Connection request error:
connection time-out.
Check the supply voltage on the encoder.
Check the Ethernet cables for the encoder for open circuit.
Check whether the IP address of the encoder matches the IP
address that is saved in the control system. Possible causes:
• The address switches are not engaged correctly.
• The encoder has lost the IP address that is assigned to it
after switching back on.
