STEP 7 is already equipped with a powerful, context-sensitive Help
system.
To be able to access current information and software updates
quickly and accurately (finding instead of searching), we now link
STEP 7 with our Internet product information system.
The following functions are possible:
 Detailed information (technical specifications, FAQs,
documentation) on modules can be queried direct from HW Config
via our Product Support pages on the Internet.
 Updating of HW Config via Internet – this provides the opportunity
of integrating individual components such as new CPUs or new
distributed I/O devices "a bit at a time" into the current version of
STEP 7 without having to install an extensive Service Pack.

Multi-project
Benefits
The Multi-project allows you to configure your systems flexibly. At
the forefront here is time-saving parallel creation of projects that can
be combined with support from the system.
With the help of the Multi-project, you can, for example, create one
project per operator for distributed processing and share the stations
among the projects according their operators.
Agreement is only needed for executing cross-project functions such
as networking.

Configuration in RUN (CiR)
There are plants that must not be shut down during operation.
Nevertheless, dismantling work or conversion work can become
necessary.
With the help of CiR, it is possible to carry out certain changes to the
hardware configuration during operation (that is, in the RUN state of
the S7-CPU). In doing so, operation of the process is interrupted for
one second at the most.
This requires the use of an S7-400-CPU (from FW V3.1*) or an S7-
400-H-CPU of expansion stage 1v1 (from FW V3.1*).
*Planned start of delivery: start of 2003

Principle of CiR
 In configuring the hardware, provision is made for later hardware
modifications by setting “CiR capability activated”.
 CiR elements are defined that can be replaced later, step-by-step, with
actual objects (slaves and/or modules) in the RUN operating state.
CiR means
 During the CiR synchronization time, the process inputs and outputs
are maintained at their last values.
 The CiR synchronization time depends on the degree of expansion of
the line (input and output bytes of the DP master system)

Address priority (symbolic/absolute)
Setting the address priority (symbolic/absolute)
In the dialog box for block folder properties, you can specify whether
the symbol or the absolute value is to have priority when opening the
blocks following changes to the symbol table. In STEP 7 versions
older than V5, the absolute value has priority.
This functionality has been expanded and is now valid for all accesses
(inputs, outputs, bit memories, timers, counters, and data blocks).
You can specify STEP 7’s behavior, from absolute access right up to
symbolic access.

Symbol table
The symbol table has been completely revised. The following
performance features deserve a special mention here:
 The previous restriction to a maximum of 16380 symbols in one
symbol table has been removed.
 The "special object properties" of the symbols are represented
clearly and are easy to edit. All the information on the symbol is
available at a glance.
 In the new "Status" column, non-unique symbols, for example, are
graphically designated. There is also a powerful filter function.
 Support for the wheel mouse.

revised:
 Address priority is taken into account when opening a table.
 If the "Symbol Comments" column is blanked out, the symbol
comments are displayed in a condensed form in the "Symbol"
column.
 Condensed information can now also be shown using the keyboard.
 The table can be maximized and minimized.
 It is possible to display force values with results.

Hardware Configuration
 New versions of the CPU 31xC have additional functions already familiar in
other CPUs, for example:
 Distributed reading and writing of consistent data (> 4 bytes)
 In "DP slave" mode, the option "Startup/test mode" can be set. This option
allows powerful execution of the programming device functions and it
enables S7 routing.
 The new S7-400-CPUs (V 3.1) offer the possibility of operating up to four
DP master systems in clocked mode with the help of OBs 61 to 64.
 Parameterization of acknowledgement-triggered signaling (SFB 33 to 35)
for CPUs used for PCS 7: if this function is activated on the tab
"Diagnostics/Clock" of CPU Properties, the above-named SFBs only report
a signal change again if the previous fault message has been acknowledged.
This prevents the piling up of messages that cannot then be processed.
 New versions of the DP/PA Link support DPV1 mode. When the DP/PA
Link is plugged in, the mode of the higher-level DP master is automatically
adopted.

 Online coordination of identification data:
 For the new ET 200M interface module (153-2AA03) and the new DP/PA
Link (157-0AA82) as well as for other signal modules of the S7-300,
modifiable identification data such as plant designation and creation date
can be coordinated (that is coordination between configuration and loaded
identification data).
 The times specified for events in the diagnostics buffer can be displayed
both as module time and as local time.
 In module status (PLC >Module Status), specific help can be called up for
many of the displayed hardware channel faults. In the case of DP slaves
integrated via GSD file, help for device-specific diagnostics can be called
up, provided the associated GSD file contains the relevant help texts.
 The module status of slaves can be called up via accessible nodes.

Topology display - diagnostics repeaters
In conjunction with diagnostics repeaters Stage 2 (6ES7 972-0AB01),
it is possible to display the topology of the PROFIBUS network in
addition to displaying PROFIBUS line diagnostics.
In contrast to the network view with NetPro, it is not the "logical"
view of a PROFIBUS sub-network that is presented but the physical
arrangement of the PROFIBUS nodes with the actual order and
distanced to the nodes.

Saving data on MMC/flash card
Since STEP 7 V5.1, we have offered the facility for storing the entire
project (programs, symbol information, comments, and HW
Configuration) on a MicroMemoryCard (MMC). We have expanded
this function too.
Now, any data can be stored along with the project data on the MMC
or, in the case of the S7-400, on the flash card.

Configuring messages
 In addition to project-wide assignment of message number, CPU-
wide assignment is also possible.
 Advantage: with CPU-wide assignment of the message numbers, a program
can be copied without the message numbers changing and giving rise to the
necessity for recompiling.
 Standardizing the message attributes
 Advantage: there are no more specifications for monitors. This simplifies
configuring.
 Integration of the message texts into the project texts
 Advantage: multi-language message texts can be exported, edited, and
centrally managed in a user-friendly way.
 Text libraries
 Advantage: users can create their own text libraries.

Report system fault
Since STEP 7 V5.1, S7 components and DP standard slaves
can initiate organization block calls when a system fault
occurs.
Example: in the event of a wirebreak, a diagnostics-enabled
module can initiate a diagnostics interrupt(OB 82).
With the function "Report system fault", STEP 7 offers a user-
friendly method of displaying the diagnostics information
provided by the component in the form of messages.
STEP 7 automatically generates the blocks and message texts
required for this. The user only has to load the generated
blocks into the CPU and transfer the texts to the connected
HMI devices.

 The function "Report system fault" can now also be used for F
systems.
 The name of the user blocks and the diagnostics blocks can be
entered as an absolute name or as a symbolic name.
 In the case of an existing block, the available parameters of the
interface are preset after the block name has been entered.
 For messages, the help texts for correcting the fault can be
incorporated into the message text or the info text.

Compatibility
In previous STEP 7 versions it was possible that the modules and the
lower-level objects were not displayed when opening a project - if the
project contained new modules unknown to that STEP 7 version.
With the new STEP 7 version, this behavior is a thing of the past:
 Effective retroactively from STEP 7 V5.1 including Service Pack 3,
all modules will be represented, even those configured with a later
STEP 7 version and therefore unknown to the "older" STEP 7.
Modules configured with an optional package will also be
represented - even if the required optional package is not installed
on the programming device used to open the project. Normally it is
also possible to delta load the new module over the Internet into
the existing version (from STEP 7 V5.2) (see also "STEP 7 goes
Internet").

Compatibility
Basic information on compatibility:
 STEP 7 V5.2 is fully upwards compatible with STEP 7 V5.1, V5.0,
V4.x and V3.x, that is, programs and projects created with these
predecessor versions can continue to be processed unchanged with
STEP 7 V5.2.
 STEP 7 V5.2 is also downwards compatible with these versions
provided no components and functions are used in a new V5.2
project that are not supported by STEP7 V5.1, V5.0, V4.x or V3.x,
such as the new CPUs or the multi-project function.
 If a project created with STEP 7 V5.2 is to be further processed
with, for example, STEP 7 V5.0, only module MLFBs that are known
to STEP 7 V5.0 must be used in the V5.2 project. In certain
circumstances, new modules must be configured with the
"predecessor MLFB".
 Effective retroactively from STEP 7 V5.1 including SP3, this no
longer has to be taken into account, since new modules unknown to
the STEP 7 version are also represented here.
 Normally new modules can be "delta loaded" with STEP 7 V5.2.
