• When a web browser is used for FTP access, data logging files, event logging files, report files, and recipe files may not be
opened directly due to the specification of the web browser. Make sure to open the files after saving them to a personal
computer.
• When a web browser is used for FTP access, due to the specification of the web browser, 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 a web browser is used for FTP access, a retry may be performed at user authentication failure due to the
specification of the web browser. Note that unintentional repeated entry of wrong passwords may lock the module.
• The following port numbers (communication protocol) are used for the FTP server function.
Port for transferring data: 20 (TCP/IP)
Port for controlling communications: 21 (TCP/IP)
■Replacement of an older version of a module
• When replacing an older version of a high speed data logger module, delete temporary internet files (caches) of a web
browser before accessing a newer version of the module.
■Connecting GX LogViewer
• The maximum number of connections for GX LogViewer to access the high speed data logger modules simultaneously is 2.
• The following port numbers (communication protocols) are used for the online function.
Connection via a hub: 49900, 49902 to 49906 (TCP/IP)
Direct connection: 49900 (UDP)
High speed data logger module search: 49901 (UDP)
■Connection with Configuration Tool
• Note that a module may be in an unintended status when operating it in multiple pieces of Configuration Tool at the same
time.
• The following port numbers (communication protocols) are used for the online function.
Connection via a hub: 49900, 49902 to 49906 (TCP/IP)
Direct connection: 49900 (UDP)
High speed data logger module search: 49901 (UDP)
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 in the manual below. 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.
