Precautions for Correct Use
• This instruction can be used only for the built-in EtherNet/IP ports on NJ/NX-series CPU Units.
• Execution of this instruction is continued until processing is completed even if the value of Execute
changes to FALSE or the execution time exceeds the task period. The value of Done changes to
TRUE when processing is completed. Use this to confirm normal completion of processing.
• Refer to Using this Section (page 2-3) for a timing chart for Execute, Done, Busy, and Error.
• Even if you use Cancel to cancel the execution of this instruction, sometimes the directory on the
FTP server is deleted depending on the timing of when Cancel changes to TRUE.
Check the directory on the FTP server.
• You can execute a maximum of 3 of the following instructions at the same time: FTPGetFileList, FTP-
GetFile, FTPPutFile, FTPRemoveFile, and FTPRemoveDir.
• An error will occur in the following cases. Error will change to TRUE.
• The value of any input parameter is outside of the valid range.
• The directory specified by SvrDirName does not exist on the FTP server.
• ".." is specified for a directory level in SvrDirName or RemoveDirName.
• An incorrect path such as "//" is specified for SvrDirName or RemoveDirName.
• The directory specified by RemoveDirName does not exist on the FTP server.
• There are no files or subdirectories in the directory specified with RemoveDirName.
• The directory specified with RemoveDirName has a read-only attribute.
