Thats a little bit like asking "Can you tell me the address of the third house on that street with the big tree on the corner that I'm thinking of."
We are going to need a lot more specific information to help you out.
erm... 47

Let me explain so you understand me better, I HOPE. Our company took over a support contract for a jail facility and what I post is what I upload from the PLC. That all I have. Question: If I upload the file from the PLC I should be able to get comments?
The PLC is a 1756-L61 Turbo Control Logix
And there is the following note...T The 1756-L6x controllers have nonvolatile memory if you install a 1784-CF64 CompactFlash card. With nonvolatile memory, the controller can be used without a battery. If you do not use a battery, current tag data will be at the state they were when the nonvolatile memory was saved.
I think you are classing the -L6x series as "turbo", which I accept they are faster than the -L5x series, but I've never heard them called "Turbo" before.The 1756-L6x controller executes ladder scans almost twice as fast as the 1756-L55 controllers and executes function block, REAL data type math, and motion instructions four to five times faster than the 1756-L55 controllers.
While you are welcome here at the Forum and we aim to be of help to fellow automation professionals, I'm going to give you one of my less pleasant bits of advice.
Stop what you're doing, and get some help.
You're close, very close, to figuring out how the controller data is mapped in the system. But if you click just one wrong thing, you're going to erase the crucial "Scanlist Map" in the 1756-DNB and you'll be out to sea without a sail.
Rockwell Automation has an office in Tampa, just south of the airport, (813)289-5320. Call and talk to Jim Redifer or Patrick Barry and get a reference from them for an integrator or one of their own field guys to come out and just run you through how to upload with RSNetworx for DeviceNet software and explain the way the data maps from the network module into the controller.
Both RSNetworx and RSLogix are comparatively easy and straightforward software tools, but in your situation and for your application, I very strongly recommend that get qualified assistance. It will be far less costly, even in the short term, than making a mistake.
