See a live demonstration www.plcdotnet.com
A Windows 2003 server is located in southeastern Florida. Over 1000 miles away in eastern Pennsylvania sits an Allen-Bradley PLC-5/40E. An ASP.NET web service uses INGEAR.NET.ABLINK to connect the PLC-5 over the internet to deliver a web page with real-time PLC data to whereever you’re setting.
All without the need for RSLinx, OPC Servers, or 3rd party software of any kind.
Using Visual Studio .NET, a few lines of code, and INGEAR.NET, you can have web-based access PLC data anywhere, and on virtually any browser, including PDA devices such as Blackberry and IPhone.
