  1. VxWorks Real-Time Kernel Connectivity

  2. What is VxWorks? • VxWorks is a real time operating system developed by Wind River for use in embedded systems.

  3. Automated Devices • It’s not always possible to monitor them directly. • How do we monitor and test them from a remote location?

  4. Monitoring DAQ Devices • A web-based toolkit allows the status of DAQ devices to be seen by users with an internet connection.

  5. Overview • The client requests the status of a device, and the host queries the target for the data.

  6. The client accesses the host, selects the page of the device for testing, and submits a form with parameters for the device. • The host forwards the form to the appropriate target. • A CGI program on the target receives the form and performs the requested tests. • The CGI response is returned to the host and forwarded to the client.

  7. Devices Target Host Web Page Target Client Web Page Target

  8. “Host” Computer • An HP Desktop PC running an Apache server and Windows XP. • Acts as a medium between the client and the target(s). • Used for development on the VxWorks computer

  9. “Target” Computer • Connected to one or more devices as well as the host. • Runs the specialized web server for communication with the host.

  10. Simple WEB Server • Last updated in 1999, and is tricky to compile now. • Written in C and designed with VxWorks in mind • Provides very basic functionality
