Which Block Version Should I Use?
The following descriptions also include information on differences between the
various block versions. Please take note of the version identifiers of the blocks you
are using.
The SIMATIC Manager block libraries installed with STEP 7 / NCM S7 contain the
block versions that were current at the time of the STEP 7 release.
Note
We recommend that you always use the latest block versions for all module types.
You will find information on the current block versions and the current blocks to
download from the Internet in our customer support.

With the older module types, this recommendation assumes that you are using the
latest firmware for the particular block type.
