Hi fellow PLC veterans, I am new in the PLC world so please forgive me if my questions read dumb to you..   I am just wondering if there are any newer PLC machines that can: 1. keep the program even after its battery is completely flat or faulty  (Is this even possible?) 2. allow users to copy and save the program somewhere so one can install the program again without the need/presence of the machine supplier What tools/software may be required?   Thank you for reading and look forward to your response :)

Hi fellow PLC veterans, Reading from your posts above, I am just wondering if there are any newer PLC machines that can: 1. Still keep the program even after its battery is completely flat or faulty  (Is this even possible?) 2. allow users to copy and save the program somewhere (as a file perhaps?) in case one needs to install the program again without the support of the supplier   Thank you in advance. :)
