1 Overview

New and Modified Functions in STEP 7 Version 4.02

The information in this supplement will familiarize you with the additional functions of STEP 7, version 4.02 in a short and concise manner.

You should already be familiar with version 4.01 of the STEP 7 software and the manual package “STEP 7 Basic Information V4.0” (Order Number 6ES7 810-4CA03-8BA0) supplied with it.

This supplement is structured in a similar way to the STEP 7 User Manual. First, you will find details of the most important updates/changes in creating and editing projects; then, information on configuring hardware, networks, and connections; and finally, notes on creating and debugging user programs.

Minor changes are not documented here. If, for example, dialog boxes have been changed, these changes are explained in the online help.

New Function: Password Protection for Access to Programmable Controllers

With the aid of password protection you can:  Protect the user program and its data in the CPU against unwanted changes

(write protection),

 Protect the know-how in your user program (read protection),  Inhibit online functions which would interfere with the process.

You can only assign a password to a module if the module supports this function. If you want to protect a module with a password, you must define the level of

protection and the password in the module parameter assignment, and then download the modified parameters to the module (see Chapter 3, New CPU Parameters).

If a password is required before an online function can be executed, the dialog box “Enter Password” is displayed. By entering the correct password you are authorized to access modules which have been assigned parameters specifying a special level of protection. You can then establish online connections to the protected module and execute the online functions which have been protected.

You can use the menu command PLC Password” dialog box directly. Here you can specify that the password entered should be used for all future access to protected modules. The dialog box will then only appear if this password is invalid.

The tabbed dialog box which you open with the menu command Options Customize has been expanded and restructured. For example, you can now

select a “Quick View” when diagnosing hardware (see Chapter 10).

3 Configuring Hardware

New CPU Parameters

There are many new components in version 4.02; for example, racks, C7 control systems, or CPUs in the hardware catalog. It is not possible to list all the updates or changes within the scope of this supplement; instead, only the new CPU parameters (which are relevant to the operation of the latest CPUs) are covered:

CPU Parameter

Test operation/ process operation

(see also Chapter 9)

Protection level Can be set in the “Protection” tab. Write access, and read

Improved Copy Function1

If you hold the CTRL key down and select several modules or DP slaves, you can then paste these modules/DP slaves at another location.

Remarks

Can be set in the “Protection” tab. In process operation, debugging functions such as “program

status” or “monitoring/modifying variables” are limited to prevent the permissible increase in the scan cycle time from being exceeded. For example, call conditions are not permitted in the program status, and the status display for a programmed loop is aborted on return.

It is not possible to debug with breakpoints in process operation, nor can you execute a program step-by-step.

In test operation, all programming device/PC debugging functions can be used without restriction, including those which result in increases in the scan cycle time.

and write access to the CPU can be made dependent on the use of a password. The password is set in this tab.

Before pasting copied DP slaves, you must select the DP master system to which the DP slaves are to be “attached.”

Improved Display and Print Functions

The changes to the display and print functions are listed below in detail, with a brief description of how each function can be used.

You can use the new menu command Options  Configure Network to switch to the application for network and connection configurations.

Working with DDB Files

The original procedure for supplying STEP 7 with new device database (DDB) files has been improved. You can now use the menu command Options DDB Files and the subsequent dialog boxes to locate the DDB file you require.

Another new feature in STEP 7, version 4.02 and above, is that type files (DDB files (.GSD)) and DP slave symbols (bitmaps) are now also stored in a project. When you configure a new station, you can refer back to the type/DDB files and symbols which were used to create another project (for example, on another programming device). The new menu command Options Files enables you to do this.

The menu command for updating the hardware catalog is now Options Catalog, rather than Options

Configuring the ET 200X (BM 147/CPU) as a DP Slave

The BM 147/CPU basic submodule is configured as an intelligent DP slave. In contrast to other intelligent DP slaves, the basic submodule can be found under “PROFIBUS DP/ET 200X/BM 147/CPU” in the “Hardware Catalog” window.

Requirement: The application “Configuring Hardware” must be running. Proceed as follows:

1. Configure the DP slave ET 200X (with BM 147/CPU) as an S7-300 station.

– Create a new station of the type S7-300 (menu command Station – Select the “PROFIBUS DP/ET 200X/BM 147/CPU” directory in the

“Hardware Catalog” window.

– Copy the object “BM 147/CPU” to the empty station window using drag &

drop.

A configuration table is created for BM 147/CPU. – Configure the DP slave with the required I/O expansion modules. – Save the station (the intelligent DP slave).

New).

2. In another station, configure a DP master (CPU with integrated PROFIBUS-DP interface or CP with PROFIBUS-DP interface; only the latest CP 342-5 (342-5DA01-0XE0)).

3. Using drag & drop, copy the DP slave ET 200X (with BM 147/CPU) from the “Hardware Catalog” window (Configured Stations container) to the symbol for the DP master system.

4. Double-click the symbol for the intelligent DP slave and select the “Link” tab. In this tab you can specify which station is to represent the intelligent DP slave.

5. Select the intelligent DP slave and click the “Link” button.

6. Select the “Slave Configuration” tab and assign the master and slave addresses to one another.

7. Confirm the settings with “OK.”
