8.1 Configuring the CPU
Requirements for configuration of the CPU
1)
1)
The following CPUs can be configured as of V12: CPU 1511-1 PN, CPU 1513-1 PN, CPU 1516-3 PN/DP
Note that all other CPUs can be configured only as of a later version (e.g. V12 SP1). Refer to the manual for the CPU to
find out whether the version of the CPU you are using is configurable in STEP 7.
Project compatibility of CPUs with firmware version V3.0
In order to download older projects to CPUs with firmware version V3.0, you must upgrade
your project to CPUs with at least firmware version 1.8 and article numbers 6ES751x-xxx01-
0AB0.
Spare parts compatibility for CPUs with article numbers ≥ 6ES751x-xxx03-0AB0
The following applies to CPUs as of article numbers 6ES751x-xxx03-0AB0:
For these CPUs, spare parts for CPUs with article numbers ≥ 6ES751x-xxx01-0AB0 are
compatible for use.
You cannot download STEP 7 projects having a hardware configuration with CPU article
number 6ES751x-xxx00-0AB0 to a CPU with article number 6ES751x-xxx03-0AB0. Exception:
CPUs S7-1500R, see above
Solution: When exchanging a CPU 6ES751x-xxx00-0AB0 for a successor type 6ES751x-xxx03-
0AB0, you must upgrade the STEP 7 project to ≥ 6ES751x-xxx01-0AB0. For the upgrade, use
SIMATIC STEP 7 ≥ V13 SP1 Update 3.
Configuring CPUs with article numbers < 6ES751x-xxx03-0AB0 in older STEP 7 versions
CPUs with article numbers ≥ 6ES751x-xxx03-0AB0 are compatible with their predecessor
version in terms of spare parts. Manipulation protection, particularly with respect to the
SIMATIC Memory Card and RUN/STOP function, is retained.
When replacing a CPU (e.g. 6ES7515-2AM01-0AB0) with a compatible successor type (e.g.
6ES7515-2AM02-0AB0), the STEP 7 project does not have to be changed, nor is it necessary
to upgrade the STEP 7 project.
You can still configure modules with new article numbers in STEP 7 as the predecessor
version (e.g. 6ES7515-2AM01-0AB0). Because the new article number (e g 6ES7 515-2AN03-
0AB0) is not yet contained in previous STEP 7 versions, you can also configure the CPU as
predecessor version, i.e. with the previous article number (e.g. 6ES7515-2AM01-0AB0).
