I need a cheap way of sending data over the internet from plc direct or Ge9030 plcs. I need to make a html web page to send commands and access data. Any ideas??
2) I used the Lite edition of OPCWare Client Developer from Data Layers. I used the samples they provide as the basis to write some ASP that delivers the HTML page, I also got great support from them when I got stuck. Look at http://www.opcware.com/OPCWare.html
Cost: $199
3) I set this up on the web server. The web server is a bog standard Windows box already located in our control room and already set up with some web pages.
Cost: $0
I can now read or write any register in the PLC from one simple web page anywhere in the world. No ActiveX or Java plug-ins on the browser. I built in a userID and password to access the page of course - we don't want anyone taking control of our plant now do we.
