NJ-series CPU Unit Built-in EtherNet/IP Port User’s Manual (W506)
This section describes the response codes stored in the output variable ErrorIDEx if an error occurs
during the execution of a CIP message communications instruction.
As response codes, general codes are stored in the
ErrorIDEx output variable (DWORD data) after exe-
cution of a CIP communications instruction is completed. If an additional code is added, the additional
code is also stored.
