The following error response codes may be returned for power interruptions. If
one of these response codes is returned or no response code is received, ex-
ecute the command again.

@00FA1244*CR
• Undefined command
@00IC4A*CR
A response code is returned with each response If a command is completed nor-
mally, a response code of 00 00 will be returned. If command execution ends
with an error, one of the response codes listed in the table in this section will be
returned in the following formats.
It is possible to determine the cause of an error from the response code. If there
was an error during network communications, bit 15 of the response code will be
ON (1). If there was an error in the PC, bit 6 or 7 will be ON ( in which case, refer to
the CV-series PC Installation Guide and correct the error).
