A host computer hosts the screen files that serve as the user interface for operators
and runs the VeriStand Gateway.
The host computer must be a PC running
a supported version of Windows.
VeriStand Gateway—Creates a TCP/IP communication channel that facilitates
communication with the VeriStand Engine over the network. The VeriStand Gateway
receives channel values from the VeriStand Engine and stores them in a table. You
can view these values using the Channel Data Viewer tab in VeriStand
Editor or the Channel Data Viewer workspace tool. If you run a
project on a desktop PC, the VeriStand Gateway initiates the VeriStand Engine.
If you run a project on an real-time target, the VeriStand Gateway
synchronizes with the system definition file that is running on the RT target. If
the system definition file currently running on the VeriStand Engine does not match
the system definition that the VeriStand Gateway expects, then the VeriStand Gateway
does not synchronize with the system definition file running on the RT target.
The following are features that you can modify.
Project File—The .nivsprj file
that defines high-level settings, such as:
The screen and system
definition files to run
Available users and their
permissions for the project
The list of tools you can
launch from the Tools Launcher
Which services run when you
deploy a project to the target
The IP address of the
Stimulus profiles and
Screen File—The .nivsscr or
.nivsscreen files that define the configuration and
settings for the screens and display items you view in the
VeriStand Editor or Workspace,
Stimulus profile—A test executive that can call real-time sequences, open and close VeriStand projects, and perform data-logging
and pass/fail analysis. It also connects real-time sequences to system definition files to bind channel data within the system
definition file to variables in the real-time sequence. Stimulus profiles execute on the host computer. You create and run
a stimulus profile using the Stimulus Profile Editor.
National Instruments Driver Software—You need the appropriate driver software to communicate with hardware installed on a
target. For a list of the required driver software, see the VeriStand Readme located at
<Program Files>\National Instruments\NI VeriStand\readme\readme.html. If you installed VeriStand to a different location, locate the readme directory in the install location you specified.
