AB PLC drivers ActiveX Control


Thread Starter


Can somebody please give the information if ActiveX control is available with which I can communicate to Allen Bradley PLC using Ethernet? I want to use this control in web page.

You might want to try an ActiveX OPC container such as that found at http://www.opcactivex.com/. However this is not an ideal solution, you may be better of writing a small program in VB or delphi that periodically collects the values from the PLC via OPC and said activeX control, and puts them somewhere your web page can access them. Otherwise you could have a lot of users accessing your OPC server via the web, this would not be good for a large number of users.

Best of luck,
