Security and HTTP, FTP, and TFTP Services
You can enhance security for your project by disabling the FTP/TFTP and HTTP services at times when you do not need to use them. The module uses the HTTP service to provide access to the embedded webpages. The module uses the FTP and TFTP services to support various features including firmware upgrades, and FDR services.
The module’s HTTP, FTP, and TFTP services can be disabled or enabled using the Security screen of the Ethernet network configuration window.
HTTP, FTP, and TFTP services are disabled by default in DTM instances created using Unity Pro 8.1 or later, with respect to the following modules and firmware versions:
-
BMX NOE 0100 firmware version 2.90 or later
-
BMX NOE 0110 firmware version 6.00 or later
-
BMX P34 20•0 firmware version 2.60 or later
NOTE: Unity Pro is the former name of Control Expert for version 13.1 or earlier.
HTTP, FTP, and TFTP services are enabled by default in instances created using previous versions of Control Expert.
You can use Control Expert to enable or disable HTTP, FTP, and TFTP services as described in the following procedure.
If the HTTP, FTP, or TFTP services have been enabled with Control Expert, they can also be enabled or disabled at run time using a DATA_EXCH function block. (See the Communication Block Library for Control Expert.)
