12-3-2 Connection Status Codes and Troubleshooting
This section explains how to identify and correct errors based on the tag data link’s connection status.
The connection status can be read using the Connection Tab Page of the Network Configurator’s Mon-
itor Device Window. Refer to 12-3-1 Checking Status with the Network Configurator on page 12-10 for
details.
Additional Information
The connection status has the same meaning as the Connection Manager’s General and Addi-
tional error response codes, as defined in the CIP specifications.
The following table shows the likely causes of the errors for each configuration and connection status
(code).

00 0000 Normal status code:
The connection has been opened
and the tag data link is communicat-
ing normally.
--- ---
01 0100 Error code returned from target:
Attempted to open multiple connec-
tions for the same connection.
This error does not occur. Depends on the originator’s specifi-
cations. (This error should not occur.
If is does, contact the originator
device’s manufacturer.)
01 0103 Error code returned from target:
Attempted to open a connection with
an unsupported transport class.
This error does not occur. Confirm that the originator supports
Class 1.
01 0106 Duplicate consumers:
Attempted to open multiple connec-
tions for single-consumer data.
If the tag data link is stopped or
started, this error may occur
according to the timing, but the
system will recover automatically.
If the tag data link is stopped or
started, this error may occur accord-
ing to the timing, but the system will
recover automatically.
01 0107 Error code returned from target:
Attempted to close a connection, but
that connection was already closed.
This error does not occur. This is not an error because the con-
nection is already closed.
01 0108 Error code returned from target:
Attempted to open a connection with
an unsupported connection type.
This error does not occur. Check which connection types can
be used by the originator. (An error
will occur if a connection other than a
multicast or point-to-point connec-
tion is set.)
01 0109 Error code returned from target:
The connection size settings are dif-
ferent in the originator and target.
Check the connection sizes set in the originator and target. Please
update tag size as described in 9-5-4 Determine Tag Sizes on page 9-40.
01 0110 Error code returned from target:
The target was unable to open the
connection, because of its operating
status, such as downloading set-
tings.
Check whether the tag data link
is stopped at the target. (Restart
the tag data link communications
with the software switch.)
Check whether the tag data link is
stopped at the target. (Restart the tag
data link communications with the
software switch.)
