3.3 Configuring DDFR Settings Files
3.3.1 What is a Settings File?
The DDFR Settings File - identified by its .DFR suffix - contains information on all the relays
associated with that particular DDFR. When a Settings File is accessed by clicking on the
Device Setup line in either the Online or Offline window (see figure 3-2), it is found to
contain the following information:
FIGURE 3–9: Contents of a Typical DDFR Settings File
This screen - essentially the contents of a single Settings File - provides information on two
relays - named
489_01 and F60_04 - that are associated with one specific DDFR. The
Settings File name itself (see the screen header) is dfr1.DFR , which is the name assigned to
it by the person who created it. Other relays can easily be added to this screen (ie: this
Settings File) as shown in section 3.3.3 below. What all these relays have in common, as
stated above, is that they communicate with this single DDFR, and are thus defined in this
single Settings File which is dedicated exclusively to that DDFR.
3.3.2 Using Settings Files
As indicated above, a DDFR Settings File is sent to a particular DDFR to configure the
relationship between that DDFR and the relays connected to it. A Settings File can also be
retrieved from a DDFR if it has been changed online (see below), in order to ensure that that
the two files are consistent (ie: contain exactly the same information) in both the DDFR and
the controlling computer. These features follow the paradigm used by all EnerVista Setup
applications.
Each Settings File is always, therefore, associated with a specific DDFR and all its
associated relays, and this association is used when transferring the setup parameters to
and from that DDFR.
