Using Fdc For Various Device Operations - Honeywell SLG 700 User Manual

3.2.8

Using FDC for various device operations

Typical operations with a smart field device involve configuration, monitoring, and diagnostics.
FDC enables the user to achieve these operations with a HART device via the various
interfaces/constructs exposed through the DD file of the device.
The "Functions" tab under the device home page provides the entry points for navigating through
the device specific user interface to perform the above mentioned operations. A device may define
up to four entry points in the DD file. All devices shall have at least one entry point, generally
referred to as "Online". Besides the device specific entry points, FDC provides custom entry points
for navigational aids to specific types of information/features. One such entry point is called Device
Status, which is used for reviewing device health. Another is called Methods List, which is used to
navigate to all the methods available in a device.
All of the device specific entry points represent the device interface, as explained using the Online
entry point as an example. All the other device specific entry points have a similar interface except
for the fact that the variables and other DD constructs provided under each may vary as indicated
by the title of each entry point.
For the sake of explanation, the pages that appear on navigating through the device
specific entry points are referred to as "Device Configuration" pages in this document.
However it must be noted that this does not prohibit the user from performing other
device operations as explained above.
Online Device Entry Point: When the user tap on to open the Online tab, the device configuration
screen appears as shown below.
