Same problem here, two cpus from two different machines are down because of this. The last one used to hang intermittently, diagnostic buffer showed memory card evaluation error. When I replaced the memory card (in power off) the CPU remained in hanged state and now wont boot at all with all LED's OFF and display showing "CONNECTING" PLCs are S7-1511T ------------------------------------------------------------------------------------------ |
