Table 28 - Error Messages
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 Edit 843ES CIP Safety Encoder Configuration
Categories on page 65).
16#0111 Requested Packet Interval (RPI)
out of range
Make sure that RPI for Safety Connection is in the appropriate range (6…500 ms) and the Standard Connection is in the
appropriate range (1…750 ms). Check that Safety Task RPI is 6 ms or greater.
16#0114 Electronic keying mismatched:
electronic keying product code
and/or vendor ID mismatched.
Wrong device selected, or incorrect major/minor firmware revision selection based on the real device. For example, single-
turn selected 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 timeout.
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.
16#fd1f Bad Safety Protocol Format An error occurred while trying to add the Safety Network Segment to a route in Logix. Check Safety Network Number on
Safety Page, refresh Safety Network Number if needed.
