1 Software Redundancy

Within WinCC, the software redundancy feature makes it possible to monitor

critical sections of a plant by using a redundant connection to several PLCs.

Software redundancy considerably improves reliability when critical plant

sections are to be monitored. For example, a redundant connection to two

PLCs means that one PLC takes over if the other PLC fails. Using software

redundancy does not mean that you can only establish redundant connections

to the PLCs configured. It is still possible to connect any PLC in a non-

redundant layout. The switchover between redundant PLCs is performed

automatically in the event of a malfunction. However, a manual switchover is

also possible by specifying a tag (@ForceConnectionState).

Note

Establishing a redundant connection requires two PLCs.

1-2Setting up software redundancy:In order to use software redundancy under WinCC, the following settings arerequired in the Control Center:Step 1

The computer properties must be set to the following values:Step 2Within the Alarm Logging system, the "short-term archive" must be

activated:If the "short-term archive" has not yet been activated, proceed as follows:In the navigation window, open the pop-up menu of the "Archives" objectand select the "Add/Remove" menu item. Within the "Assign StorageParameters" dialog box, activate the "Short-Term Archive Active" checkbox.

Step 3

Within the Alarm Logging, the system messages must be retrieved; select

the "Options" and "WinCC System Messages" menu items for this

purpose. In the "WinCC system messages" dialog box, activate the "Create

New System Messages Only" option and press the "Create" button. This

procedure retrieves the system messages associated with software

redundancy.

1-4Step 4By means of the "DynWizEdit.exe" program, integrate the DynamicWizard for software redundancy into the WinCC system (GraphicsDesigner). This integration procedure requires the following steps: In theWindows Explorer, start the "C:\Siemens\WinCC\bin\DynWizEdit.exe"program. Select the "German" language in the toolbar. Retrieve the"C:\Siemens\WinCC\wscripts\wscripts.deu\SW_Redundanz.wnf" script byselecting the "Dynamic Wizard" and "Retrieve Wizard Script" menuitems. The compilation progress is shown in the output window. After thecompilation has been completed successfully, the new entry "Establish

Redundant Connection" appears in the "Dynamic Wizard" window.Step 5Integrate the "SIMATIC S7 PROTOCOL SUITE" communications driverwithin the tag management.Step 6Within the required bus type (e.g. MPI), create a logical connection in the"SIMATIC S7 PROTOCOL SUITE" communications driver. Give anexpressive name to this connection.Step 7Open an existing picture in the Graphics Designer. Within the Dynamic-Wizard (in the "System Functions" tab), start the "Establish Redundant

Connection" program by double-clicking.

Step 8

Press the "More" button in the welcome screen.

Step 9

Select the main connection in the "Set Options" dialog box. Then press the

"More" button.

Step 10

1-6Edit the settings for the back-up connection in the "Set Options" dialogbox. Then press the "More" button. The "Automatic Switchover" check

box must be active (default setting).The settings for the back-up connection (S7 network address) can be foundin the "Connection" tab. Access this tab via the connection properties

dialog box for the connection.

Step 11

The settings you specified are displayed in the final "Finished" dialog box.

By pressing the "Finish" button, connection-specific internal tags are

created in a tag group. This tag group is stored within the tag management

under "SIMATIC S7 PROTOCOL SUITE" and the associated channel

unit.Note
