Hello, I have a customer that is a predicament. The automation company that they used for years went under water and left them with very little PLC program and wiring information.
Find new and reconditioned PL7 Schneider Software at EU Automation. Free 1 year warranty on all parts. Concept 26; Unity SFC. For comparing 2 Modicon TSX Micro.
They have a plc system with alot of IO. Using Modicon Quantum CPUs. The p/n for the cpu is 140CPS11420. Can someone help with what software I well need to connect to this. They did give me program on a USB that might be right thing but they don't know. I tried it with my SoMachine v.4.1 and that can't open the files that they gave me, but I don't know if these are the right files or not. Can someone please give me some advice?
SoMachine is definitely no help to you. Likely to be ProWorx32 or possibly even modsoft based on the age of that CPU model. What's the file extension? 
It's possible that they upgraded to Unity Pro firmware but no way to know without connecting to the CPU using proworx, unity or the OSLoader tool.
I would contact Schneider and see if they have a tech who can help you. Someone with the right tools can point you in the right direction with only a few minutes work. They may even offer his time for free if there's the potential for upgrade. Note that the Quantum range is now considered mature and a lot of CPUs are reaching obsolescence. This does appear to be some old software! I got a download setup file for the Concept v.2.6, but I didn't realize it has to be XP. It cant run on my laptop.
Might need to find an XP machine somewhere. Those familiar with Concept programs: I suppose it is pretty likely that like in many softwares nowadays the upload is passwordable? That is another thing I fear that I get all setup, but then the program cannot be even accessed. I've never even attempted an upload.
Earlier versions of Concept software didn't even support uploads, which made it very important to carefully manage the program backups.
