Web-enablement Technologies
You can use VEE to disseminate data you have collected in programs, to
monitor test systems, or to review test results remotely. This section
describes web-enablement technologies for test and measurement
applications, and how VEE supports these technologies.
Overview of Web Technologies
This example describes how to create a web site internal to an organization
(an intranet web site) that provides reference data as a server. It assumes that
users accessing this site have browsers. The example uses a Microsoft
environment (Windows 95, Windows 98, Windows NT 4.0, or Windows
2000), MS Office, and MS Internet Explorer. The communication will go
from the instrument to the server, and then to the client browser, as shown in
Figure 12-4.
Note This example uses PC screen dumps. VEE is also web-enabled on HP-UX.
Figure 12-4. Model of Web Measurement Application
In Figure 12-4, the communication is as follows:
n The device under test (DUT), or sensor, or instrument sends information
to the server application through the network I/O layer. The network I/O
layer includes the interface and backplane (GPIB, RS232, VIX, MXI, PC
Plug-in), and the I/O programming layer such as drivers, VISA, or SICL.
