I have a web server enabled HMI (Beijers) connected to a PLC in my plant. This HMI is on our plants ethernet network. I can compose a webpage for the HMI and FTP the file to the HMI. The HMI will then serve the web page. The web page contains special SSI and CGI scripts that allow PLC register values to be viewed or changed in the web page.

I want to be able to, from the SQLServer machine, pull data from this web page. Can this be done using the winHTTPrequest object in VB? Anyone ever done anything like this?
