Hello med_selmi; You are using a CPU 318-2DP? You do know that this model of CPU was a compromise between a S7-300 and S7-400 PLC, it was actually a small S7-400 packaged as a S7-300. Read this FAQ, and pay special attention to the following note: "SIMATIC S7-400 CPUs The "Copy RAM to ROM..." function is not supported by S7-400 CPUs and the CPU S7-318 2DP. The options offered by the S7-400 are given in Entry ID 23670531." https://support.industry.siemens.com/cs/us/en/view/15389520 Hope this helps, Daniel Chartier |

Thank you Daniel, now I know the only way for CPU 318 is to use load user program on memory card, but this function is enabled only with offline project, so if I make a back-up then I load this back-up to EPROM, is there problem with Data blocks? Shall I put machine in initial position before doing this? |
