==Module Description File==
Keeping track of which register serves what purpose can be a challenge, especially for the application specific registers. But this is where the module description file or MDF comes in. The MDF file is a machine-readable XML file describing the function of each register of a module, giving the configuration options for that register, etc. This file is used by configuration software (VSCPWorks) to show configuration options specific for the module addressed. The MDF file can be stored on the node itself and fetched from there by
VSCPWorks, but more commonly the MDF file will be an XML file hosted on a webserver somewhere. A node then just needs to inform VSCPWorks where (URL) the XML file can be found. This URL is present in the VSCP reserved registers 0xE0-0xFF.
