Hello,
In case of using external RAM memory, If you have intact fiber optic connection , with no fault, download to rack#0 suffices.Configuration and user program will be transferred automatically to other CPU.Read more in getting started section of this manual(PAGE#41): SIMATIC Fault-tolerant systems S7-400H (V6.0)In case of using FLASH memories, test your config without external memories.When you are sure your hardware is working properly, you need copy the data to Flash and test the system again.(Identical program on flash). I hope it helps you, hdhosseini |
