Hi, I'm pretty new to plc programming. My current project at work is to design a c++ program that will be able to communicate to an allen bradley SLC 505 plc via ethernet. ultimatly, i'm looking for the pc to recieve data from the plc, use that data to search an sql database, and then return a value from the database back to the plc. Is there any source code or drivers to do the communications? i would prefer freeware, just to see if I would be able to do it. Then I could spend money on a more expensive package if i need to.
Thanks a lot for all your help.
