FTP Client Function4-424.4.3.2 Transfer Control (FTPcCTL)Sets to enable, disable or cancel the transfer of FTP client.• CY (SR9) and SD29 are cleared to 0 when this instruction is executed.(Set when Ethernet is initialized.)• It is necessary to specify the transfer settings before executing the instruction using 4.4.2.2Transfer Settings (FTPcSET) or 4.4.1.2 to 4.4.1.7 File Transfer Settings with the toolsoftware. (when control taget is specified with transfer number)• It is necessary to specify the transfer settings before executing the instruction using 4.5.2.1Logging/Trace Transfer Settings (FTPcLOG) or 4.5.1 Setting with Tool Software with the toolsoftware. (when control taget is specified with LOG number)• It takes some time to accept the processing of the transfer cancel request. Check thetransfer status and check if the transfer stops after executing the instruction. For informationon how to check the transfer status, refer to the case that S1 operand is"FTPc/HHTPc/SMTPc) in 4.4.3.3 Information Acquisition of Ethernet Unit (ETSTAT).
