Hello Med_selmi; The CPU 318-2DP was a strange beast, a S7-400 disguised as a S7-300 CPU. This was done to give more power to S7-300 projects that required it at the time. The subsequent S7-317 and S7-319 CPUs were designed with higher processing speed and more memory, so Siemens stopped production of the CPU 318-2DP. See the quote from Ayman Elotaifi in the first post of this discussion for help in selection of a replacement CPU: Note however that the CPU 318-2DP is still available as spare part, if you want to maintain the same processor in your project. https://support.industry.siemens.com/cs/products/6es7318-2aj00-0ab0/cpu318-2dp-512kb?pid=214641&mlfb=6ES7318-2AJ00-0AB0&mfn=ps&lc=en-US This generally means that the unit is more expensive than a regular module. You can contact Spare Parts yourself (use the Services link above) or ask a Siemens rep. to find price and availability for you. Hope this helps, Daniel Chartier |

thank you very much Daniel, I noticed sometimes a strange state of cpu 318-2dp : sometimes all its LED flashes and sometimes I can't load modification because of memory problem . So even I find spare part, I want to replace this cpu. I think cpu 317-2dp will be the best choice. |
