Good evening, we have a machine in our plant that uses the PLC 7CP476.60-1 and we need to make a backup of the program that is in this PLC. I have tried with Automation studio 3.0.90 in windows 7 with serial connection and creating a new project, I was able to load the hardware configuration, but what I cannot do is recover or upload the program that is in the PLC, could you help me please?
Thanks
Roger
