I have a PLC with an S7-314 IFM CPU which I want to change its hardware configuration for communication purposes. As far as I try to change the Hardware cinfiguration the more I try the less it change. The CPU is equipped with ROM, I tried the "Copy Ram to ROM" in Step7 no error comes on but no change happens. the CPU is of the old types with 4 position selector and battery. I guessed may be there is a jumper or key on the CPU in order to protect the ROM. Can anybody help me ?
