Download Link : Click Here 

In order to work with the STEP 7 V5.5 SP2, you need a suitable programming device or a suitable PC. There are no special hardware requirements. Therefore, the minimum requirements specific to the operating system apply. You can find these requirements on the appropriate Microsoft websites.

In addition, you will need an external prommer for SIMATIC memory cards / MMC if you are using a PC and want to save your user programs to EPROMs and a SIMATIC NET interface if you want to use online functions with your personal computer for the automation system.

As of STEP 7 V5.5, you can use the USB prommer without installing additional software. The necessary functionality has been integrated in STEP 7.

Operating systems

STEP 7 V5.5 SP2 can be used with the following operating systems:

·         MS Windows XP Professional SP2 or SP3 (32 bit)

·         MS Windows Server 2003 R2 SP2 (32 bit) Standard Edition as workstation computer

·         MS Windows 7 32 Bit Ultimate, Professional Enterprise (standard installation), with or without SP1. The Windows XP mode under Windows 7 has not been approved yet.

·         MS Windows 7 64-bit Ultimate, Professional and Enterprise, with or without SP1.

·         MS Windows Server 2008 R2 (64-bit), with or without SP1.

STEP 7 has not been tested on any other operating systems; use at your own risk.

Important additional information:

·         Special considerations when installing the software on MS Windows Server 2008:
You need administrator rights to configure the PG/PC interface or install hardware support packages. The user rights from the user group "Siemens TIA Engineer" are not sufficient.

·         Special consideration when installing the software on MS Windows 7: Observe the notes in the paragraph "Special Characteristics of the MS Windows 7 Operating System" regarding the user group "Siemens TIA Engineer".

Internet Explorer

All operating systems must be using MS Internet Explorer 6.0 (or higher).

Display of PDF files

To read the supplied PDF files, you need a PDF reader that is compatible with PDF 1.7 (ISO32000-1:2008 PDF).

Security settings

In project directories, all users who have write access are to receive write permission in case of non-exclusive use by one user only. These rights have to be set up by an administrator.

Note: The standard rights available in the operating system depend on the operating system in use. Tools used for the creation of partitions will implement their own security guidelines.

Hibernation mode

Shifting to hibernation mode is generally permitted in STEP 7. However, hibernation must not be triggered if online connections are open or projects are being accessed by STEP 7 applications via a network.

In such cases, online connections could be terminated unintentionally and open projects on networks may experience data loss.

For these reasons, the energy options for the operating system in the Windows Control Panel should be set so that hibernation is not automatically triggered (by timer). Hibernation should not be triggered manually by the user in the cases mentioned above.

1.1  Memory Requirements

Memory requirements for STEP 7

Depending on your installation requirements and the number of languages installed, STEP 7 V5.5 SP2 requires between ca. 650 MB and 900 MB of memory on your hard disk. The exact value also depends on your operating system and on the file system used on your programming device/personal computer.

MS Windows swap file

The supported Windows operating systems also require additional free space on the hard disk (typically C:) for their swap files, depending on the memory configuration. You should keep at least double the value of the RAM free. (Example: If you have 512 Mbytes of RAM, you will require another 1024 Mbytes of free space on the hard disk for the swap file after STEP 7 has been installed.) Depending on the size of the project, it may be necessary to have a larger swap file, for example, when copying an entire project (twice the size of the project on the hard drive in addition). If the free memory area for the swap file is too small, errors may occur (the program could possibly crash). Additional Windows applications which run parallel to STEP 7 (such as Microsoft Word) also require additional hard disk space for the swap file.

In order to ensure that the required memory for the swap file is really available, the minimum size for the swap file should be set to the above value. This can be set in Windows (for example, Windows XP Professional) in the taskbar in Start > Settings > Control Panel (in System > Advanced > System Performance > Settings > Advanced).

You must make certain that you have enough free memory on the drive where the project data are located. If there is not enough memory on the drive, the project data may be destroyed during an operation (for example, when compiling an STL source file into blocks). We also recommend that you do not store the project data on the same drive as the Windows swap file.

1.2                    Compatibility with Other Software Products

1.2.1              Rational ClearCase

STEP 7 projects must not be stored on ClearCase drives; that is, drives that are linked to a ClearCase View (MVFS).

1.2.2              Network Settings when using Other Software Products

If you are using other software products (for example, mail providers) on a programming device or PC with STEP 7, observe the additional notes on network settings in the section "Using Network Drives".

2                     Installation

2.1                    Installing STEP 7 V5.5 SP2

When installing STEP 7 V5.5 SP2, you can overwrite existing installations of STEP 7 V5.1, V5.2, V5.3, V5.4 or V5.5 while observing the authorized operating systems (refer to Chapter 3.1). You do not have to uninstall these STEP 7 versions and optional packages prior to the installation.

Before starting the Setup program, close all applications (such as Microsoft Word, etc.) and the "Control Panel" window, because you will need to restart Windows following the installation of STEP 7 V5.5 SP2 so that all system variables can be entered completely.

Insert the STEP 7 DVD in the drive. The setup program will guide you through the installation. The setup program starts automatically after the STEP 7 DVD is inserted in the drive. If you have disabled this function on your computer, start the setup program by double-clicking the SETUP.EXE program in the root directory.

In the component selection box, select the Adobe Reader, STEP 7, the Automation License Manager and any other components that you wish to install.

If you would like to change the installation path suggested in the setup during the STEP 7 installation, please note that you cannot install it directly to a root directory (e.g. D:) on your computer. There has to be at least one higher-level folder such as "STEP7", for example, D:\STEP7.

These components will then be installed.

The following notes are intended to help you make the correct user entries required during the Setup program:

• ·         The drive on which you install STEP 7 V5.5 SP2 can be selected freely. On some PCs/programming devices, you will not be able to select the drive via the selection list. In this case, simply enter the drive with its path in the appropriate input box (for example, "e:\Siemens/Step7"). For practical reasons, STEP 7 optional packages should also be installed on this drive, so there must be sufficient space available (see "Memory Requirements"). Avoid installing STEP 7 on a SUBST drive.
• ·         Before you use STEP 7 V5.5 SP2, Windows must be restarted. Only then do all of the Microsoft Windows entries become active. If you do not restart Windows, STEP 7 V5.5 SP2 cannot run properly and data may be lost. If the installation procedure is aborted, you will also need to restart Windows.
• ·         Refer to the tables in the S7KOMP_B.PDF file (in the directory "Step7" following installation) for information on which versions of the optional packages can run with STEP 7 V5.5 SP2 under the respective operating systems.
• ·         STEP 7 must not be installed in a directory whose path includes characters that are not listed in the ASCII character set (refer to the section “Note on Using Foreign-Language Character Sets”).
• ·         The security settings of your system are modified during installation. During the installation, you will be informed of the changes made by STEP 7.
• If you are using additional firewall software, you may have to ensure that the exceptions made in the Windows Firewall are also taken into consideration in your additional firewall software.
