5.3.3 EIP Error Codes
The gateway error codes are listed in this section. Error codes returned from the
command list process are stored in the command list error memory region. A
word is allocated for each command in the memory area. The error codes are
formatted in the word as follows: The least-significant byte of the word contains
the extended status code and the most-significant byte contains the status code.
Use the error codes returned for each command in the list to determine the
success or failure of the command. If the command fails, use the error code to
determine the cause of failure.
Note:
The gateway specific error codes (not EtherNet/IP/PCCC compliant) are returned from within
the gateway and never returned from an attached EtherNet/IP/PCCC slave device. These are error
codes that are part of the EtherNet/IP/PCCC protocol or are extended codes unique to this
gateway. The most common errors for the EtherNet/IP/PCCC protocol are shown in the following
tables:
