I cannot go online or download to my SLC-505. I recently purchased another license for RSLogix500, but I don't think this has anything to do with it. When I try to connect I get "Going online requires FactoryTalk Security user authentication." I think this has to do with the fact that the "processor secured" box in the controller properties is checked, (which I would like to be able to turn off as well). I recently had to change the Ethernet IP address, and since I haven't been able to connect. I can ping it, but I just can't get through with RSLogix.
