What''s New in STEP 7, Version 5.3?
The following subject areas have been updated:
Installation
· STEP 7 is released for MS Windows 2000 Professional and MS Windows XP Professional.
· As of STEP 7 V5.3 there is a new licensing procedure. User rights are no longer issued by means of authorizations but now by means of license keys. License Keys are managed in the Automation License Manager. The "AuthorsW" program is no longer used.
Printing
· The paper size and page layout (headers and footers) in all applications can now be
specified with the File (or the corresponding menu item in the specific application) > Page Setup. This no longer has to be done centrally in the SIMATIC Manager.
· As of SP 1, you can include the storage path of the object to be printed as a predefined key field in the footer or header.
SIMATIC Manager
· The "Compare Blocks" dialog box how has the option "Compare Details". To select the path for comparing blocks, click the "Select" button.
· Data that you have saved to an MMC or Memory Card are displayed in the "Your project files" folder, which is located below the block folder.
· There are new symbols for libraries. All user-created F-libraries, which only run on Fsystems, are now supported. To create F-libraries, select the File > New > Libraries
menu command. In the "New Project" dialog box that is displayed, select the "F-library" check box.
· The menu command PLC > Diagnostics/Setting > Node Flashing Test lets you identify the node directly connected to the programming device (PG)/PC by means of the flashing FORCE LED.
· As of SP 1, you can remove objects in a multiproject (e.g. projects, subnets and
connections) from the multiproject so that you can edit them. To do this, select the File > Multiproject >Remove for Editing menu command.
· As of SP 1, you can return previously removed objects to the multiproject, regardless of their call environment. To do this, select the File > Multiproject > Reapply After Editing menu command.
· As of SP 1, the "Compile and download objects" dialog box was augmented to include the "Select All" and "Deselect All" buttons. These new buttons allow you to conveniently select or deselect multiple objects all at once from the selection table.
Programming LAD/STL/FBD Blocks
· The "Call Environment of the Block" dialog box now allows you to manually enter call paths that were previously not detected by means of the cross-reference function in the reference data display.
· If the program editor show the current block status, you can now display the current status values in the LAD and FBD languages in decimal, hexadecimal or floating-point format.
· In the dialog box displayed after selecting the Options > Customize you can go to the "General" tab and specify whether the program status change for blocks should take place automatically whenever the maximum number of blocks that can be monitored has been reached.
· As of SP 1, when a function block is open, you can update data blocks and adjust
interfaces. To do this, select the File > Check and Update Accesses menu command.
· As of SP 1, when inserting symbols, you can choose in the "View" tab whether the
addresses in the address selection list should be alphabetically sorted by name or the
absolute address. To do this, select the Options > Customize menu command.
· As of SP 1, the symbolic name of a block is also displayed in the title bar of the program editor.
· As of SP 1, symbolic names that are longer than the specified address field width are split and continued on a subsequent line ("word-wrapped") after special characters in the name
(e.g. +, -, *, /, %, =, space, _) in order to improve readability.
Symbol Table
· Within a symbol table, you can now select and edit contiguous areas. This means that you can copy and/or cut parts of one symbol table and insert them into another symbol table or delete them as required.
Configuring and Diagnosing Hardware
· The previous "H" optional package "S7-400H Fault-Tolerant Systems" is no longer supplied as a separate optional package; instead, it is now integrated in STEP 7 V5.3. To open the related electronic manual "S7-400H Fault-Tolerant Systems", go to the task bar and select Start > SIMATIC > Documentation. The block library "Redundant IO" contains blocks for supporting redundant I/O devices.
· You can now search for components or any text strings desired in the Hardware Catalog.
· You can now search for information (product support, FAQs, and, as of SP1, also manuals) on modules and components directly via an Internet address. Provided information on the module is available, you will be taken to a page that contains a selection of information. To do this, select the required module from the Hardware Catalog or in the module rack, rightclick to open the context-sensitive menu listing the information options available.
· New modules with new functions are now supported:
· You can assign parameters to the new "Option Handling" function for ET 200S.
· You can issue a location ID for CPU 41x-xxx04.
· As of SP 1: You can now search in HW Config for manuals for modules and components.
To do this, select the desired module in the Hardware Catalog or in the rack. Then rightclick to display a context-sensitive menu. In this menu, select the "Find Manual" menu command.
· As of SP 1: Support for PROFINET IO.
· As of SP 1: When downloading hardware updates, Internet connections via proxy servers with authentication are supported.
Configuring Networks and Connections
· NCM S7 Industrial Ethernet and NCM S7 PROFIBUS, the configuration tools for S7 CPs, are no longer separate software packages, but are now automatically installed with STEP 7 V5.3.
· The network view can now be switched over to a view with reduced subnet lengths. This provides a clearer overview of projects, especially those with numerous stations.
· The CPU 317-2 PN/DP supports S7 communication as a client via its integrated PROFINET interface. You will find the communication blocks in the standard library (Communication Blocks, CPU_300, see Blocks for Different Connection Types).
· Errors and warnings are now displayed in a newly designed output window for consistency testing. This window is clearly structured in columns and has menu commands for locating the error position, to display the help on the specific message and for printing.
· Connections (including cross-project connections) can be downloaded to stations from a central point with the function "Compile and Download Objects". If the object used as a starting point is a multiproject, then all stations involved in a connection are automatically loaded, regardless of which project the station is located in.
· As of SP 1: In general, handling of multiprojects has been improved: There is a general view of multiproject with all cross-project subnets. From this view, you can also download to the stations in the multiproject. In addition, the calculation of bus parameters and the assigning/checking of PROFIBUS addresses has been improved for merged PROFIBUS subnets.
· As of SP 1: Support for PROFINET IO.
· When you print a project that is part of a multiproject, the text printout (print option:
"Network Text") always includes the multiproject information, which is added at the end of the printout.
Standard Libraries
· The standard library "System Function Blocks" has been expanded with the blocks SFC85 for creating retentive or non-retentive data blocks as well as SFC112, SFC 113 and SFC 114 for use in PROFINET communication.
· As of SP 1, the standard library "System Function Blocks" has been expanded with the blocks SFC 70, SFC 71 and SFB 81 for determining addresses and reading parameters with PROFINET IO.
· The standard library "Communication Blocks" has been expanded with the blocks for S7 communication for CPU 317-2 PN/DP (CPU_300).
· As of SP 1, the standard library "Communication Blocks" has been expanded with the blocks FB 63, FB 64, FB 65 and FB 66 for open TCP/IP communication.
· The symbols used for libraries are new. You can now identify which libraries are usercreated F-libraries, which can only be run on F-systems.
· As of SP 1, the standard library "Organization Blocks" has been expanded with OB 65 for CPU 317T-DP.
Process Diagnostics
· The new Process Diagnostics > Import Templates menu command lets you import
templates for process monitoring in S7-PDIAG.
Managing Multilingual Texts
· With STEP 7 V5.3, in addition to CSV format you can now use XLS format as an export format.
Report System Error
· As of SP 1, ET 200 eco is supported.
