The cause of errors that occur when using the SEND(090), RECV(098), or
CMND(490) instructions can be identified from the response codes. (Refer to
the description of Communications Port Completion Codes in 8-6-4 Writing
Programs for the storage locations of response codes generated by the
SEND(090), RECV(098), or CMND(490) instructions.)
This section describes the completion codes produced by EtherNet/IP Units.
For details on completion codes produced by CPU Units, other CPU Bus
Units, or computers equipped with FINS services, refer to the device’s opera-
tion manual.
