DD Methods and DD Menu
Overview
Fieldbus technology has enabled a broad range of functions to be covered by a field device
alone. Conversely, it has resulted in increased parameters to support these increased
functions. To alleviate intricate operations due to the multiplied parameters and to provide
easier-to-use user interfaces, fieldbus technology offers a menu facility and interactive
guidance facility called methods, to be incorporated in device descriptions (DDs). With a
field device whose DD contains a pre-embedded menu and methods, you can easily and
intuitively access desired parameters and perform a series of setup operations.
A DD menu and DD methods are features embedded in a DD file for a field device,
therefore, software supporting them needs to be used on the host computer for fieldbus
system configuration. Make an inquiry to the software supplier about whether and how the
software you use supports DD menus and DD methods. This User’s Manual describes only
the DD menu and DD methods of the FVP110.
DD Methods
DD methods guide you in setting parameter procedures properly. Simply following
instructions given by DD methods accomplishes the intended parameter setting without
accessing a wrong parameter or failing to follow the correct setting procedure. In principle,
accessing the individual parameters can also make the settings that can be made using DD
methods.
As for the FVP110, there are twelve DD methods for the transducer block, two for the AO
block, and one for the OS block. The following describes these methods for each block
model.
