3. New features of STEP 7 V5.5
We have summarized the important new features of STEP 7 V5.5 in a set of overhead slides
In addition a list of the new features:
List of newly supported modules:
  • STEP 7 V5.5 is fully upwardly compatible with STEP 7 V5.4, V5.3, V5.2, V5.1, V5.0, V4.x and V3.x, i.e. programs and projects created with these versions can be further processed with STEP 7 V5.5 without any changes.
  • STEP 7 V5.5 is also reverse compatible with these versions under the condition that a V5.5 project does not contain components and functions which are not supported by STEP 7 V5.4, V5.3, V5.2, V5.1, V5.0, V4.x or V3.x, e.g. new CPUs or new functions.

    • If a project created with STEP 7 V5.5 is to be further processed with STEP 7 V5.0, for instance, the V5.5 project may only contain module order no.'s which are known to STEP 7 V5.0. It may be necessary to configure new modules with the "predecessor order no." in this case.
    • In the reverse case down to STEP 7 V5.1 incl. SP3 it is not necessary to consider the above restriction, because here it is possible to also represent new modules that are not known to the STEP 7 version.
  • From STEP 7 V5.2 and higher many new modules can be "post-loaded".
