Security and HTTP, FTP, and TFTP Services
The module uses HTTP services to provide access to its embedded Web pages. The module uses FTP and TFTP services to support various features including firmware upgrades, FDR services, and Ethernet remote IO.
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 PlantStruxure EIO Version 1.5 and Unity Pro 8.0 or later. They are enabled by default in instances created using earlier versions of Unity Pro.
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 an MBP_MSTR block with operation code FFF0 (hex).
