3.3 Installing NI-FBUS
ValveNavi software interfaces to the fieldbus segment through an interface card that must
be installed in the PC running ValveNavi. The card is supplied with NI-FBUS installation
software. ValveNavi is designed to operate only with National Instruments NI-FBUS cards,
which are AT-FBUS, PCI-FBUS, or PCMCIA-FBUS.
Prior to using ValveNavi, install the NI-FBUS card and its software in accordance with the
instructions provided by National Instruments, Inc. Note that the instructions are different
for the AT card used in a desktop and the PCMCIA card normally used with a laptop.
Furthermore, the instructions are different for Windows 2000, for Windows XP, and
Windows Vista.
Note that there are two NI configuration tools that serve separate purposes:
• NI-FBUS Interface Configuration Utility- This is used to install and set up interface
boards. It provides access to IRQ and memory settings needed for Windows. It
provides tools for importing DD’s. It is described in the Getting Started manual
supplied with the NI-FBUS interface card.
• NI-FBUS Fieldbus Configuration System- This is the tool for configuring the
Foundation fieldbus network, including the devices, setting up the control strategy, and
schedule. It is described in the NI-FBUS Configurator User Manual installed in the
program online help. After opening the NI-FBUS Fieldbus Configuration System, click
Help>>Online Help to open the manual in PDF format.
WARNING
Do not configure the interface as a Link Master when connecting to the segment with an
existing host. Disruption of control may result.
3.3.1 Configure the NI-FBUS interface card safely for different
tasks
The configuration of a portable PC for use with ValveNavi will vary depending on the
immediate task. If ValveNavi will be used to maintain or configure a valve on an existing
Foundation fieldbus segment, the PC running ValveNavi must configured carefully so it
does not interfere with control communication. Two configurations are described in the
following sections.
Table 3.1 Two configurations of the NI-FBUS Interface Card
T0301.EPS
To configure a positioner in the Foundation
fieldbus segment with a host computer. The NI-FBUS Interface card must be configured as a BASIC
DEVICE at a Visitor address.
To configure a positioner in the segment
without other host (Initial Setup, for example). The NI-FBUS Interface card must be configured as a LINK
MASTER DEVICE at a FIXED address (0
ϫ10 is
recommended).
NOTE
A Visitor device will not start until connected to a running segment with an active LAS that
can assign a node address to the visitor.
