Hello I wonder if you deleted Data Blocks "DB_WORK_NO", "DB_SEND_NO" and "DB_RCV_NO" (typicallyDB1, 2 & 3) online after you made the change to FC100 and before you restarted the CPU? If not it would explain your problem and chapter 5.8 of the SIMATIC S7-300/S7-400 Software redundancy for SIMATIC S7 manual has more on this. I hope this helps |
