FTP Client Function
 Processing
• The setting for the server connected to the FTP client is specified in the CPU unit according
to specified parameters.
• It can be executed when all the transfer request relays of FTPc control relay and FPTc
logging/trace control relay are set to 0: No request and when "Add-on" is set to "Use" in the
built-in ET-LAN setting. (In the case other than the abve, an operation error is occurred.)
• CY (SR9) and SD29 are cleared to 0 when this instruction is executed. (Set when a specified
IP address is out of range.)
• The initial value is setting with the instruction when the server setting is not specified.
• The unit configuration data of Ethernet never be rewritten. When the unit configuration data
has been already set, it is overwritten and the data becomes invalid.
• When an incorrect IP address is specified, an error is set to CY flag and it becomes no
operation.
• It is executable when the Ethernet initialization active (X61) is OFF. If it is ON when
executing the instruction, an error is set to CY flag and it becomes no operation.
 Precautions during programming
• When specifying a device for an operand in which character constant can be specified, set
string data beforehand with SSET instruction.
• When specifying string data, the number of characters should not execeed 256.
• Upper and lower case characters can be used for operands which character constant can be
specified.
("Abcd", "ABCD" and "abcd" are synonymous, however, the file names are differentiated.)
• A target unit for the instruction is specified with UNITSEL beforehand.
• This instruction is not available in interrupt programs.
 Operand [S1] setting
• Specify the starting address storing the server specification parameter or a character
constant.
• A part of parameters can be omitted. The settings are not changed when parameters are
omitted partially.
• When omitting the part before a specified keyword, omit only "keyword" without omitting ",".
• When omitting the part after a specified keyword, omit both "," and "keyword".
• Specify the FTP server setting from SV0 in order. When the right order is skipped, an error
occurs. It is possible to specify when the setting has been already registered.
• Only one server can be specified at the same time.
• Specify an FTP server number, IP address or host name of FTP server, port number, open
method, and SSL3/TLS1 authentication within 256 characters in total.
• It is prohibited to specify the same keyword redundantly. If specified, an error occurs.
