CPU 315-2DP SF/STOP on FM357

Dear Experts,

Good day!

I have to replace the old cpu (315-2AF03-0AB0) with (315-2Ah14-0AB0), first i download the new HW configuration the cpu run with no error but when i download the program the cpu stop with sf error (i/o access reading) adrress 352 which is the adrress of FM357 module. Via diagnostic stacks FC2, FC22 cause of error but it is lock and standard program for FM module..

See screen for info.. thanks for the help..<<

Best Regards

It seems to me you don't have a configuration inside the FM since you changed CPU and disconnected powersupply. If you never generated SDBs for the FM, you can not change module without PG. So now I think you should go into FM config tool (parameter button insede FM HW Cofig), connect online with CPU and download FM configuration.

Regards!
