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 T
ab Page of the Network Configurator’s Mon-
itor Device Window. Refer to 16-2-1 The Network Configurator's Device Monitor Function on page
16-3.
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 causes for each configuration and connection
status (code).
