Converting an S5 File STEP 7, Version 5.4

Converting an S5 File

As of V5.4 SP2, you can use Options > Customize to assign STEP 7 blocks to be converted from STEP 5 blocks to user-defined block numbers and thereby retain the block numbers of the earlier STEP 5 function blocks.

Operating/monitoring variables

As of V5.4 SP 2, you can now easily replace addresses in the variable table using the menu command Edit > Find/Replace.

Configuring Networks and Connections STEP 7, Version 5.4

Configuring Networks and Connections

·         PROFINET IO with IRT Communication (Isochronous Realtime) is supported. This means that short and equal-length bus-cycle times can also be configured for PROFINET IO (see Introduction: Isochronous Realtime Ethernet).

·         There is improved handling when inserting copied IO devices into another station. If the IP addresses are already assigned, you can specify the action to be taken upon insertion (retain addresses or assign new ones).

·         In a manner similar to that for PROFIBUS DP slaves, you can now set the watchdog time for PROFINET IO devices: as an object property of the IO device in the "IO Cycle" tab.

·         When using optical components for PROFIBUS DP: when configuring with an optical ring, you can specify the optical link modules (OLMs) to be used. This makes calculation of bus parameters more exact. In addition, it means that the bus cycle time can be shortened when higher-performance components are being used.

Standard Libraries

·         The standard library "Communication Blocks" has been expanded with the blocks FB 67 and FB 68 for open TCP/IP communication.

·         The standard library "Communication Blocks" has been expanded with the blocks FB 20, FB 21, FB 22 and FB 23 for cyclic accessing of user data in accordance with the German PROFIBUS User Organization [PROFIBUS Nutzerorganisation e.V. (PNO)].

·         In addition to the existing redundancy library "Redundant IO (V1)", there is the new block library "Redundant IO CGP" (channel granular peripheral devices). It supports redundancy for single module channels. You can find further information in the context-sensitive block help or the STEP 7 readme file. A current list of supported modules is available under the FAQs here: http://support.automation.siemens.com/.

·         As of V5.4 SP2, the system functions for SFC 109 "PROTECT“ have been expanded for activation of write-protection.

Report System Error

·         As of STEP 7 V5.4, a data block (DB 125) for PROFIBUS is supported. This data block can be used to output diagnostic events on an HMI device.

·         As of V5.4 SP1, you can export messages and error texts after you have generated them.

·         As of V5.4 SP1, you can use the unique name of the station from the S7 project in the message information that you configure in the "Messages" tab.

·         As of V5.4 SP2, you can specify values for any type of reporting component, which can be used in the generation of messages.

·         As of V5.4 SP2, the support for AS I links has been expanded.

Diagnostics

·         As of STEP 7 V5.4 SP1, maintenance information is displayed for certain PROFINET IO components (see Hardware Diagnostics and Troubleshooting).

·         As of STEP 7 V5.4 SP1, the module information functions for PROFINET IO interfaces and their ports on CPUs with an integrated Ethernet interface have been expanded by the "Communication Diagnostics" tab (see Module Information Functions) when the module supports this function.

·         As of V5.4 SP2, the functions of the module information for diagnostic repeaters as been expanded with the "DP Cycle Time“ tab.

·         As of V5.4 SP2, the functions of the module information for PROFINET IO devices has been expanded with the "Identification“ tab.

·         As of V5.4 SP2, the "Network Connection“ tab of the module information is now also displayed for PROFINET IO ports.

·         As of V5.4 SP2, the "Statistics“ tab of the module information now has two views.

·         As of V5.4 SP2, the "Module Information“ dialog box has been expanded with the current protection level of your CPU.

Configuring and Diagnosing Hardware STEP 7, Version 5.4

Configuring and Diagnosing Hardware

·         The "Information and Maintenance" process is supported in order to be able to read identification data from or write identification data to modules. This function is also available in the SIMATIC Manager (see Identification & Maintenance (I&M)).

·         Identification data can also be written to PROFIBUS DP interface modules during redundant mode (by means of "Accessible Nodes"). The interface module must support this function.

·         As of V5.4 SP1, you can also download identification data over PROFINET lO (see Entering or Changing M Data in HW Config).

·         CAx data can be imported and exported. In this way, data can be exchanged between STEP 7 and CAD systems or CAE engineering systems (see Exporting and Importing CAx Data)

·         The firmware for PROFIBUS DP interface modules can also be updated during redundant mode, as long as such a module will support this process. Each of the redundantly used interface modules can now send the updated firmware through the active backplane bus to the other, redundant interface module.

·         The "Software Redundancy" function now allows PA links with subordinate PA slaves to be copied and redundantly inserted (see Configuring SW Redundancy)

·         Applications for editing objects in HW Config can now be started with the Edit > Open Object menu command (see Opening Objects in HW Config).

·         You can configure a watchdog time for PROFINET IO devices (see Configuring the Watchdog Time)

·         You can have module times displayed in the local time of your programming device (PG)/PC.

·         As of V5.4 SP1, you can download language-specific information to CPUs to allow you to read information online with a Web browser in the required language (see Configuring the CPU for Web Access).

·         As of V5.4 SP2, you call tools external to STEP 7 from HW Config to configure distributed devices (see Integrating Tools for Configuration of Distributed Devices (TCI; Tool Calling Interface)).

·         As of V5.4 SP2, the PROFINET Topology Editor is included in STEP 7. It contains a graphical and tabular view, and online views with diagnostic information.

·         As of V5.4 SP2, you can configure additional PROFINET IO devices with IRT (S7-CPU, ET200, ScalanceX).

·         As of V5.4 SP3 you can assign asset IDs to modules within the framework of asset management. These asset IDs are then available to the TIA Maintenance Station (see Assigning Asset IDs).

Additional PROFINET IO functions are available with SIMOTION/Scout:

·         As of V5.4 SP2, you can configure "direct data access" to F modules (SINAMICS_Integrated) for special SIMOTION CPUs / D4x5 controller as lower-level I slaves (see Direct Data Access to a Module in the Lower-level I Slave). This can only be done within the context of SIMOTION/Scout!

·         As of V5.4 SP2, you can configure intelligent IO devices in IRT mode (see What You Should Know about Configuring Intelligent IO Devices). This can only be done within the context of SIMOTION/Scout!

·         As of V5.4 SP2, you can set update times for PROFINET IO devices in IRT mode as can be done for PROFINET IO devices of the RT classes (see Update Times for Cyclic Data Exchange). This can only be done within the context of SIMOTION/Scout!

·         As of V5.4 SP2, you can configure redundant sync masters for a PROFINET IO configuration with devices in IRT mode (see Configuring Redundant Sync Masters). This can only be done within the context of SIMOTION/Scout!

What's New in STEP 7, Version 5.4?

Operating systems

As of STEP 7 V5.4 SP3, the MS Windows Vista 32 Business and Ultimate operating systems are also supported.

SIMATIC Manager

·         There are two formats available for displaying the date and the time. You can select a display in the respective STEP 7 national language and or in ISO 8601 standard format. To make this setting, go to the SIMATIC Manager, open the "Customize" dialog box and select the "Date and Time" tab.

·         You can have module times displayed in the local time for your programming device (PG)/PC. To make this setting, go to the SIMATIC Manager, open the "Customize" dialog box and select the "Date and Time" tab.

·         You have the option of restricting access to projects and libraries by assigning a password to them. In order to do this, you must have installed SIMATIC Logon V1.3 SP1 and SIMATIC Logon V1.4 SP1 under MS Windows Vista (as of now referred to as SIMATIC Logon) (see What You Should Know About Access Protection).

·         After setting up access protection for projects and libraries, you have the option of keeping a change log that records online actions such as "Download", "Operating Mode Changes", and "Reset". In order to do this, you must have installed SIMATIC Logon V1.3 SP1 and SIMATIC Logon V1.4 SP1 under MS Windows Vista (as of now referred to as SIMATIC Logon) (see What You Should Know About Access Protection).

·         As of V5.4 SP3, the supplied PKZip V8.6 CLI archiving program is provided as a standard component for archiving and retrieving projects and library. Under MS Windows Vista, ARJ.exe,  previously supplied on the CD is no longer installed for this operating system due to lacking compatibility. PKZip V8.6 CLI supports the ZIP format that is standard in STEP 7 and which can also open some other archive formats, such as ARJ. If the previously used archive format is no longer available under MS Windows Vista, or if it is not supported by PKZip, retrieve your projects on the platform you have used to date and archive them again with PKZip V8.6 CLI.
