AB PLC interchanging data with servers

[biskvito]

Hi, does anyone know how to communicate an Allen Bradley PLC with a Server to interchange data like values of variables, databases, etc?

I need to do this in order to make a program developed in RSLOGIX5000 interact with a program maybe developed in C++, Visual Basic, or another language; Making them interchanging numeric, string or floating values.

thanks in advance.

Yeps - RSLinx (any version besides Lite) or KepServerEX will be your "OPC Server" - basically a hardware driver with an API. Your application will be the "OPC Client", putting in read/write requests. The OPC Foundation and other organizations have sample code, although getting started isn't the most straightforward thing.
