Did you try putting PLC to run from the mode switch on CPU? If yes, can you post info from Diagnostic buffer? |

You'll have to put PLCs in RUN-P mode via STEP 7 (PCS7) since newer CPUs doesn't have hardware switch position Run-P. |

Dear, DS SURESH KUMARis absolutely right, we need not to download the program in both PLC, it should be downloaded in rack-0 PLC ONLY. And on connecting the FO patch cord between the plc, the rack-1 PLC will sync with the rack-0 PLC automatically. But one more thing to be noted here is that it may few minutes (i.e 5-10 min) to sync depending on the program size. so my advise tohexeis, First download the program only in rack-0 PLC, while turning off the rack-1 PLC or by disconnecting the FO patch cord. After downloading, kindly turn on the rack-1 plc or connect the patch cord. Wait of sometime to synchronize. Reg, Ashish

hi, for an H station you need to download the only hardware configuration to both the CPU's whereas you only need to download the program to one CPU.
