• When Internet Explorer is used for FTP access, data logging files, event logging files, report files, and recipe files may not
open directly due to the Internet Explorer specification. Make sure to open the files after saving them to a personal
computer.
• When Internet Explorer is used for FTP access, due to the Internet Explorer specification, errors may not be displayed even
if the transfer failed when files are transferred to the SD memory card which does not have enough free space. Update the
display and check if the files are transferred normally.
• When Internet Explorer is used for FTP access, a retry is performed at user authentication failure due to the Internet
Explorer specification. Note that unintentional repeated entry of wrong passwords may lock the module.
■
Connecting GX LogViewer
• The maximum number of connections for GX LogViewer to access the high speed data logger modules simultaneously is 2.
■
Connecting configuration tools
• Note that the module may be in an unintended status when operating it from multiple configuration tools at the same time.
Considerations for security
• Although the high speed data logger module supports basic authentication (account setting) using user names and
passwords, it does not completely protect the system from illegal access. Avoid accounts (user name, password) consisting
of simple alphanumeric characters only, and include some non-alphanumeric characters ($, &, ?) to create a complicated
user name and password.
Considerations for using SD memory cards
■ SD memory card file/directory
• Do not create files (excluding module operating files and recipe files) or folders on the SD memory card with a personal
computer. If files or folders are created on the SD memory card with a personal computer, they may be deleted.
■
SD memory card to be used
• Use SD memory cards manufactured by Mitsubishi Electric Corporation. If any other SD memory cards are used, a failure
such as data corruption on the SD memory card or a system shutdown (module major error (error code: 2450H) occurs in
the CPU module) may occur during an operation. (

■ When turning OFF or resetting the CPU module
• When a CPU module is powered OFF or reset while writing data to an SD memory card, the processing to write data to the
SD memory card may not be completed. It may cause a loss of logging data during the processing, corruption of data in the
SD memory card that is being accessed, or occurrence of a file system error. The file is automatically recovered when the
high speed data logger module is powered ON again, but it will not succeed in some cases.
The operation, powering OFF or resetting the CPU module after stopping file access, should be considered. For the
important data, a periodic backup is recommended.
