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?
