kaiser_will, thanks so much, that makes complete sense. It really is obvious when you look at it like that. I'll try to connect through the 01 channel, and see how that goes.  I won't be able to get back to the plant until next week, but I'll report back on what I find.  Thanks all, for the help!!

I am trying to connect to the MonoFloBoxSnap PLC, IP address 192.168.2.10. I connected via DF1 and Ethernet I/P. I can see everything else connected to the network, but when I try to do anything with the actual processor, "00, CompactLogix Processor", I can't. 

Thanks for all the help everyone! I will attempt to get a copy of version 17.004 installed on my computer...perhaps I can make a virtual XP machine, or possibly find an actual XP machine somewhere. pcmccartney7 - The machine is actually running, so there has to be something installed. But the fact that it has no Online Name in Linx is exactly why I thought the connection was not working. And I will need to get a copy of the existing program off of the PLC - I do not have an existing backup. I will try again to connect over RS-232. Perhaps that is the issue.  

Second issue first: I did try to connect via Ethernet I/P and RS232 separately, with the other disconnected. I just connected them both for the screenshot. In both cases, the "00, CompactLogix Processor" is non-responsive. In the I/P connection, it shows an "X" as you see; in the DF1 connection it just doesn't respond - as shown in the image below.  I do know that the processor is version 17, but I am hoping I will be able to download the program using version 19... I can't seem to get version 17 to install on my Windows 7 laptop. But since I can't even get a status on the PLC in RSLinx, I'm thinking there is a communication issue outside of what versions of RSLogix I have. I'm hoping that if I can get it to talk in Linx, then I can troubleshoot the version issue. Thoughts?

I'm having trouble communicating with a CompactLogix L32E processor. There are a pair of photoeyes that are not functioning, and I believe they may be forced on in the program, but I can't get online with the PLC to check. My ABB vendor said I was using the wrong version of RSLogix 5000 at first, but now I have tried connecting with versions 14, 19, 21, and 24. I think the version I will actually need to use is 19. However, I can't even get the PLC to communicate using RSLinx. I am using RSLinx Lite, which might be the problem. I have tried connecting via ethernet over the local switch in the machine, via ethernet directly to the PLC, and via RS-232 directly with the PLC.  I've attached some screenshots...I would really appreciate any help or advice!
