7. INTEGRATED VALVE INTERFACE (IVI)
The main application screen of ValveNavi is the Integrated Valve Interface (IVI) that is
displayed after a successful logon (ValveNavi Logon). It monitors the operation state
and status of the valve. It provides access to all other services.
Figure 7.1 IVI
ValveNavi operation begins with the Integrated Valve Interface, IVI. The IVI is a window
with a menu bar, a toolbar, a status bar, and frames containing displays and controls for
fieldbus data objects. Each of the data objects relates to Foundation fieldbus parameters.
The menu and tool bars provide access to services to work with files, devices and blocks.
The status bar shows status of the fieldbus segment. The frames are used to group the
device list tree, positioner data, Analog Output (AO) Block, and PID scheduling status, and
block modes, as well as device tag.
IVI displays all valve and positioner variables and provides access to services such as
Setup Wizard, Configuration, Calibration, and Diagnostics tools. The information and
controls for services are logically arranged in frames within IVI. From the IVI the user has
single click access to the PID Controller interface. IVI displays and updates real time values
for valve position, valve setpoint, and actuator pressure, etc.
The IVI offers tools and wizards using standard Windows conventions, offering multiple
paths to functions to suit a user’s preferences. When the cursor is moved over an icon, a
Tool Tip appears to identify the icon’s purpose.
