Outline of operation
● This instruction configures the settings for enabling or disabling transfers for an HTTP client.
● Before executing this instruction, use "17.17 HTTPcSET (HTTP Client Transfer Setting)" or
the programming tool software "FPWIN GR7" to configure transfer settings.
● It takes some time to accept the processing of the transfer cancel request. After executing
the instruction, check the transfer status to see if the transfer stops. For details on checking
the transfer status, refer to "17.3 ETSTAT (Acquiring Ethernet Unit Information: FTP/HTTP/
SMTP)".
