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 DTM Browser Security screen.
HTTP, FTP, and TFTP services are disabled by default in DTM instances created using TSX ETC 101 module firmware version 2.04 or later and Unity Pro 8.1 or later. They are enabled by default in instances created using previous versions of Unity Pro/Control Expert.
NOTE: Unity Pro is the former name of Control Expert for version 13.1 or earlier.
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.)
