	I hope that the answer will help, if you have still questions, don't hesitate to ask me. All the best, Late Never say never, think in solutions, not in trouble......

What I've added to the fail-safe program is: since I want to use FB82 (motor control) in the standard program, I have tryed to make visible the needed variables from the fail-safe program. Instead of duplicating every comand from fail-safe program to a defined byte in the memory, I've created a data block that contains the status for the bytes needed for FB82. So it looks like the fail-safe program can't read/write the bytes in the data block. What do you think? 3.Also because this is a programming error OB (OB121), and it is called up during run, how can I see inside OB121 (detailes, code errors. etc.)? The question is the same also for OB70, 72, 80, 82 etc. Thank you.

The question is the same also for OB70, 72, 80, 82 etc. 1. In the diagnostic buffer ... 2. Are you having a program extended as a failsafe program ? When you for example extended the program with standard code between the Failsafe program then it will not work... 3. Every OB have 20 bytes of header information where all kind of information is showed, in the handbook of the Standard blocks for the S7-300/-400 are the variables described.
