Installation Procedure

Preparing for Installation

Before you can start installing the software, Windows 95/98/NT must be started.

• You do not require an external data medium if the STEP 7 software was shipped on the hard disk of your programming device.

• To install STEP 7 from diskette, insert disk 1 in the floppy disk drive of your programming device or PC.

• To install from CD-ROM, insert the CD-ROM in the CD-ROM drive of your PC. Starting the Installation Program

To install the software, proceed as follows:

1. Start the dialog box for installing software under Windows 95/98/NT by double-clicking on the ”Add/Remove Programs" icon in the ”Control Panel". 2. Click on ”Install."

3. Insert the disk (disk 1) or the CD-ROM and click on ”Continue." Windows 95/98/NT searches automatically for the installation program SETUP.EXE. 4. Follow the instructions displayed by the installation program step by step. The program guides you step by step through the installation process. You can switch to the next step or the previous step from any position.

During installation, queries are shown in dialog boxes for you to answer and options are displayed for you to select. Read the following notes so you can reply to the queries faster and easier.

If a Version of STEP 7 Is Already Installed...

If the installation program finds another version of STEP 7 on the programming device, it reports this and prompts you to decide how to proceed:

• Abort the installation so that you can uninstall the old STEP 7 version under Windows 95/98/NT and then start the installation again, or

• Continue the installation and overwrite the old version with the new version. Your software is better organized if you uninstall any older versions before installing the new version. Overwriting an old version with a new version has the disadvantage that if you then uninstall, any remaining components of the old version are not removed.

Selecting the Installation Options

You have three options open to you to select the scope of the installation:

• Standard configuration: all languages for the user interface, all applications, and all examples. Refer to the current Product Information for the memory capacity required for this configuration.

• Minimum configuration: only one language, no examples. Refer to the current Product Information for the memory capacity required for this configuration.

• User-defined configuration: you can determine the scope of the installation, selecting which programs, databases, examples, and communication functions you want to install.

ID Number

You will be prompted during installation for an ID number. Enter this ID number which you will find on the Software Product Certificate. Otherwise your STEP 7 Standard software will only function as a demo version.

Using Authorization

During installation, the program checks to see whether an authorization is installed on the hard disk. If no authorization is found, a message appears that the software can be used only with an authorization. If you wish, you can run the authorization program immediately or continue the installation and execute the authorization at a later date. In the first case, insert the authorization diskette when you are prompted to do so.

PG/PC Interface Settings

During installation, a dialog box is displayed where you can assign parameters to the programming device/PC interface. You will find more information on it in "Setting the PG/PC Interface."

Assigning Parameters to Memory Cards

During installation, a dialog box is displayed where you can assign parameters to memory cards.

• If you are not using memory cards, you do not need an EPROM driver. Select the option ”No EPROM Driver".

• Otherwise, select the entry which applies to your programming device.

• If you are using a PC, you can select a driver for an external prommer. Here you must specify the port to which the prommer is connected (for example, LPT1).

You can change the set parameters after installation by calling the program ”Memory Card Parameter Assignment" in the STEP 7 program group.

Flash-File Systems

In the dialog box for assigning memory card parameters, you can specify whether a flash-file system should be installed.

The flash-file system is required, for example, when you write individual files to or delete individual files from an EPROM memory card in SIMATIC M7 without changing the remaining memory card content.

If you are using a suitable programming device (PG 720/PG 740/PG 760) or external prommer and you want to use this function, select the installation of the flash-file system.

If Errors Occur during the Installation

The following errors may cause the installation to fail:

• If an initialization error occurs immediately after starting Setup, the program was probably not started under Windows.

• Not enough memory: you need to have at least 100 Mbytes of free space on your hard disk for the standard software, regardless of the scope of your installation.

• Bad disk: verify that the disk is bad, then call your local Siemens representative.

Completing the Installation

If the installation was successful, a message appears on the screen to tell you this. If any changes were made to DOS files during the installation, you are prompted to restart Windows. When you have done this, you can start the basic STEP 7 application, the SIMATIC Manager.

You can also choose to start the SIMATIC Manager straight from the final installation dialog.

Once the installation has been completed successfully, a program group is created for STEP 7.
