Notice
Please remember that if you replace a module, you must only use the blocks
permitted for the configured CP type in the user program.
This means:
If you replace the module without adapting the configuration data to the
possibly newer module type, you do not need to make any changes to the
blocks used.
If you replace the module and you do adapt the configuration data to the newer
module type, you must use the block versions approved for this module type.
We recommend that you always use the latest block versions for all module types.
With the older module types, this recommendation assumes that you are using the
latest firmware for the particular block type.
You will find more information on replacing blocks in our Customer Support on the
Internet.
The manuals for specific devices /2/ contain information on the compatibility of the
S7-CPs and the corresponding blocks (FCs / FBs).
