Can any one point me in the derection on how to set up an ASP web page that can control a plc connected on my com port "modbus RTU" , so i can see data over the internet.

 

Well, it's not ASP, but the MatPLC can do a similar job with Zope. There's an on-line demo at http://www.ace-lab.com/SCADA/demo.html

(I'm not sure you'll have much luck getting Open solutions for ASP, which your topic selection seemed to indicate...)

In constructing ASP pages:

Do you just want to "see" data? Or do you also want to "flip switches"?

Please post a bit more info.

 

It's simple. With a good component that encapsulate Modbus protocol (via serial link or ethernet) and some knowledge of ASP programming the problem is done.

I'm in the final part of the development of a dll for the platform .NET, that encapsulates the protocol MODBUS (primary for serial links). If you want I can send you a demo, together with examples of as using it from vb.net, c# or asp.net.

 

I'm developing a dll that encapsulates the protocol modbus for the platform dotNet to be used in anyone of their languages ( VB.NET, C#, ... ). With this is simple to make an ASP.NET web page chord to your requirements, so much to see data of the PLC, like to "flip switches". If you want , i send to you a demo, with some examples of use.

I would be interested in that. We use several factorycast modules, but the Java thing is a pain.

 

Hi.

Here is the demo component and a demo project (.zip 80kb):
http://200.40.51.145/severits/sITSModbusNet.zip

It's a fully functional demo but with the following restrictions: only
support Ascii data mode and only have coils functions.

Please send me feedback.
