Precautions
• Be sure to implement security such as setting login passwords to modules that have FTP server function.
• Operating system software and add-on library cannot be read or written.
• When a file that is not supported is transmitted, an error occurs at startup, or an unexpected operation may occur. For files
to be transmitted, check that they have been correctly written from MT Developer2 and have had an operation check before
transmitting the files.
• Use file names that can be specified by a Motion CPU when using the file transmission via FTP server. Upper case and
lower case characters are distinguished from eachother thus operation may fail if using the incorrect case.
• Only ASCII characters are supported for file names and data. Do not transmit files in UNICODE format. Transferring these
files may lead to an unexpected operation.
• If the Multiple CPU system power supply or network communication is shut-off during file transmission, the transmission
fails and the file may be corrupted. When the transmission fails and the file is corrupted, write the file again. Also, when
start-up fails, initialize the memory of the Motion CPU.
• Do not perform FTP transmission or access the same file from multiple modules.
• When large files such as cam data are in the Motion CPU and the location of the file to be accessed is near the end, it may
take time until the command is completed.
