Exchanging a V3.0 CPU for a V4.0 CPU
Web server
If you exchange a V3.0 CPU for a V4.0 CPU, your Web server project settings (Page 603)
for activating the Web server and whether or not to require HTTPS access will be the same
as they were in V3.0. You can then configure users, privileges, passwords (Page 604), and
languages (Page 603) as needed to use the Web server. If you do not configure users with
additional privileges, then you are limited as to what you can view from the standard Web
pages (Page 609). The S7-1200 V4.0 CPU does not support the former pre-configured
"admin" user and password.
Formerly, the Data log Web server page provided a "Download and Clear" operation. The
V4.0 Web server File browser page (Page 622), from which you access data logs, no longer
provides this feature. Instead, the Web server provides the ability to download, rename, and
delete data log files.
Transfer card incompatibility
You cannot use a V3.0 transfer card (Page 125) to transfer a V3.0 program to a V4.0 CPU.
You must open the V3.0 project in STEP 7, change the device to a V4.0 CPU (Page 142),
and download the STEP 7 project to your V4.0 CPU. After you have changed your project to
a V4.0 project, you can then make a V4.0 transfer card for subsequent program transfers.
GET/PUT communication
By default, GET/PUT communication was enabled in V3.0. When you replace your V3.0
CPU with a V4.0 CPU (Page 142), you see a message in the compatibility information
section stating that GET/PUT is enabled.
Motion control support
S7-1200 V4.0 CPUs do not support the V1.0 and V2.0 motion libraries. If you perform a
device exchange for a STEP 7 project with V1.0 or V2.0 motion libraries, the device
exchange substitutes compatible V3.0 motion control instructions (Page 455) for the V1.0 or
V2.0 motion library instructions at compile.
If you perform a device exchange for a STEP 7 project that contains two different motion
control instruction versions (V3.0 and V4.0), the device exchange substitutes compatible
V4.0 motion control instructions (Page 455) at compile.
During a device exchange from V3.0 to V4.0, the motion control Technological Object (TO)
version automatically changes to V4.0. The TO structure is different between V3.0 and V4.0.
All associated blocks change as well. Block interfaces, watch tables, and traces update to
the new V4.0 structure. You can find the differences between the V3.0 and V4.0 motion
control axis parameters in the following two tables:
