Advant controller 31 07 KR51
Where I can find/download software 907 PC331 (for DOS), because that software was used when project was downloaded to PLC, and I found that only with that software it can be uploaded from PLC.
Second question is about internal battery in Advant controller 31 07 KR51, I red that is rechargeable battery soldered on a printed-circuit board inside PLC. Our PLC is more then 15 years in operation non-stop.
Will be software in PLC lost if we switch off PLC because battery is probably in very bad condition?

Most probably ABB (France) could explain how to buy that software, in case it is possible. The product is obsolete (I think from end of 2015).
In case the CPU is AC31 07KR51, the software is called AC31GRAF (it is Windows based, not DOS).
But... the upload of application from the CPU is not possible. You need to have the source code / the project saved on disk.
2. Incorporated battery is for backup of retain data ONLY - variables.
The application/program is saved in Flash EPROM, so it can't be lost/erased even if the internal battery is out of service
From the manual about the battery:
The life time depends on the use of the CPU. A normal case:
- the power supply is OFF every night life time = 15 years
- the power supply is OFF every week-end and day-off life time = 12 years
- the worst case power supply is every week for 4 days life time = 6 years3. I have a good expertise with AC31 series 50 PLC's and many applications realized with it. And I can strongly recommend to replace it with AC500 (eCo).
I don't know for translation tool for the application software, so you have to re-write it. But that is easy in case you have the old project
