Exchanging a V3.0 CPU for a V4.1 CPU

B.1

Exchanging a V3.0 CPU for a V4.1 CPU

You can replace your V3.0 CPU with a V4.1 CPU (Page 77) and use your existing STEP 7

project that you designed for the V3.0 CPU. You cannot upgrade a V3.0 CPU to a V4.1 CPU

by firmware update; you must replace the hardware. When you replace a V3.0 CPU with a

V4.1 CPU, you might also want to check for and apply firmware updates (Page 348) to your

connected signal and communication modules.

Note

No device exchange possible from V4.1 to V3.0

You can exchange a V3.0 CPU for a V4.1 CPU, but you cannot exchange a V4.1 CPU for a

V3.0 CPU after you download the configuration. If you want to view or otherwise use your

existing STEP 7 V3.0 project, make an archive of your STEP 7 V3.0 project prior to the

device exchange.

Note that if you have not downloaded the exchanged device configuration, you can undo it.

After downloading, however, you cannot undo the exchange from V3.0 to V4.1.

You need to be aware of some configuration and operational changes between the two CPU

versions:

Organization blocks

With V4.1, you can configure OB execution to be interruptible or non-interruptible (Page 58).

For projects from former V3.0 CPUs, STEP 7 sets all OBs by default to be non-interruptible.

STEP 7 sets all OB priorities (Page 58) to the values they were in the V3.0 CPU STEP 7

project.

You can subsequently change the interruptability or priority settings if you choose.

The Diagnostic error interrupt OB start information references the submodule as a whole if

no diagnostics event is pending.

433

Exchanging a V3.0 CPU for a V4.1 CPU

B.1 Exchanging a V3.0 CPU for a V4.1 CPU

CPU password protection

STEP 7 sets the password protection level (Page 87) for the V4.1 CPU to be the equivalent

password protection level that was set for the V3.0 CPU, and assigns the V3.0 password to

the "Full access (no protection)" password for the V4.1 CPU:

V3.0 protection level

V4.1 access level

No protection

Full access (no protection)

Write protection

Read access

Write/read protection

HMI access

Note that the V4.1 access level "No access (complete protection)" did not exist for V3.0.

Web server

If you use user-defined Web pages in your V3.0 project, store them in your project

installation folder under the subfolder "UserFiles\Webserver" prior to upgrading your project.

If you store your user-defined pages at this location, saving the STEP 7 project will also save

the user-defined Web pages.

If you exchange a V3.0 CPU for a V4.1 CPU, your Web server project setting for activating

the Web server and HTTPS setting will be the same as it was in V3.0. You can then

configure users, privileges, passwords (Page 253), and languages 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 254). The S7-1200 V4.1 CPU

does not support the former pre-configured "admin" user and password.

The S7-1200 V3.0 Web server Data log page provided a "Download and Clear" operation.

The V4.1 Web server File browser page (Page 254), 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 61) to transfer a V3.0 program to a V4.1 CPU.

You must open the V3.0 project in STEP 7, change the device to a V4.1 CPU (Page 77), and

download the STEP 7 project to your V4.1 CPU. After you have changed your project to a

V4.1 project, you can then make a V4.1 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 V4.1 CPU (Page 77), you see a message in the compatibility information section

stating that GET/PUT is enabled.

434

Exchanging a V3.0 CPU for a V4.1 CPU

B.1 Exchanging a V3.0 CPU for a V4.1 CPU

Motion control support

S7-1200 V4.1 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 307) for the V1.0 or

V2.0 motion library instructions at compile.

If you perform a device exchange from a V3.0 CPU to a V4.1 CPU for a STEP 7 project that

contains two different motion control instruction versions (V3.0 and V5.0), the device

exchange substitutes compatible V5.0 motion control instructions (Page 307) at compile.

During a device exchange from a V3.0 CPU to a V4.1 CPU, the motion control Technological

Object (TO) version does not automatically change from V3.0 to V5.0. If you want to upgrade

to the later versions, you must go to the Instructions tree and select the required S7-1200

Motion Control version for your project as shown in the table below:

CPU version

Allowed motion control versions

V4.1 (motion control V5.0)

V5.0 or V4.0 or V3.0

V4.0 (motion control V4.0)

V4.0 or V3.0

V3.0 (motion control V3.0)

V3.0

The TO structure is different between motion control versions V3.0 and V5.0. All associated

blocks change as well. Block interfaces, watch tables, and traces update to the new motion

control V5.0 structure. You can find the differences between the V3.0 CPU and V4.1 CPU

motion control axis parameters in the following two tables:

Instruction changes

The following instructions have changes in parameters or behavior:

● RDREC and WRREC (Page 146)

● CONV (Page 109)

HMI panel communication

If you had one or more HMI panels (Page 20) connected to your S7-1200 V3.0 CPU, the

communication to the S7-1200 V4.1 CPU depends on the type of communication you use

and the firmware version of the HMI panel. Recompile and download your project to the CPU

and the HMI and/or update your HMI firmware.

436

Exchanging a V3.0 CPU for a V4.1 CPU

B.1 Exchanging a V3.0 CPU for a V4.1 CPU

Requirement to recompile program blocks

After exchanging a V3.0 CPU for a V4.1 CPU, you must recompile all program blocks before

you can download them to the V4.1 CPU. Additionally, if any of the blocks have know-how

protection (Page 89) or copy protection bound to a PLC serial number (Page 90), you must

remove the protection before you compile and download the blocks. (You do not, however,

need to deactivate copy protection bound to a memory card.) After a successful compile, you

can reconfigure the know-how protection and/or PLC serial number copy protection. Note

that if your project includes any blocks with know-how protection that an OEM (Original

Equipment Manufacturer) provided, you must contact the OEM to provide V4.1 versions of

those blocks.

In general, Siemens recommends that you recompile the hardware configuration and

software in STEP 7 and download to all devices in your project after the device exchange.

Correct any errors that compiling the project finds, and recompile until you have no errors.

Then, you can download the project to the V4.1 CPU.

S7-1200 V3.0 projects might not fit in S7-1200 V4.1 CPUs

S7-1200 V4.0 added a reserve area of 100 bytes to each DB to support download without

reinitialization.

You can remove the 100-byte reserve area from DBs prior to attempting to download a V3.0

project to a V4.1CPU.

To remove the 100-byte reserve area, follow these steps before you perform the device

exchange:

1. From the TIA Portal main menu, select the Options > Settings menu command.

2. From the navigation tree, open the PLC programming > General node.

3. In the "Download without reinitialization" area, set the memory reserve to 0 bytes.

437

Exchanging a V3.0 CPU for a V4.1 CPU

B.1 Exchanging a V3.0 CPU for a V4.1 CPU

If you have already performed the device exchange, you must remove the 100-byte reserve

from each block individually:

1. From the project tree, right-click a data block from the Program blocks folder and select

Properties from the shortcut menu.

2. In the Data block properties dialog, select the "Download without reinitialization" node.

3. Set the memory reserve to 0 bytes.

4. Repeat for each data block in your project.

Refer to the S7-1200 Programmable Controller System Manual for complete details on the

V4.1 features.
