How can i change an old cpu 319-3-pn/dp with exactly the same new cpu ?

Hi all 

If i want to replace an old cpu 319-3-pn/dp with exactly the same new cpu (319-3-pn/dp)

but to use MMC card that has the old cpu 

Can someone tell me how can i do it ? 

Hello,

first you should check if the new PLC have the same FW like the old PLC.

Do you change the same Type or different type (Check the Ordernumbers of the PLC)

If you use the same type you can use the old MMC without any other canges in the new PLC.
