Pandawa Posts: 5 Rating: (1)	I have a problem with the PLC 115U, --- Power supply not live a green light does not light, check the voltage until after at 250VAC .. Is my Power Supply is damaged? --- If my power supply off and I change, whether the program in the CPU / Eprom will be lost? I wait for the answer

So without Eprom installed, the program is lost if you change the supply. you have Eprom so after powering up the new supply the program will be loade in Ram again. Regards, Marcjan

Can you go online and save all? Maybe it is possible to provide power directly via rack.
