Software for Schnider M340

I am trying to complete a project that has been abandoned. The CPU has a run light lit so I am guessing it has some sort of program. I am looking for the correct software to communicate and hopefully extract the program. Also they have some 140 CPS CPU's would these use a different software? any help would be appreciated
Thanks

M340 will use Unity Pro / Control Expert depending on how long it has been sitting abandoned. You need the "S" version or higher for M340. "S" stands for small, and is cheapest package available. Contact your Schneider Rep is my suggestion. Control Expert will run for a few weeks without a license so you can just use it like that to try upload what's there.

140CPS is a power supply for a Quantum PLC. It -might- be running Unity Pro if they have updated their firmware in the last 5 years or so. Find out what software they use and come back to us.

If you are purely looking to upload the program and not make any changes you can also use unity loader which is a free software for down/uploading to the plc and upgrade its firmware

Thankyou I will try that.
