CPUs for demanding tasks
There is a graded range of CPUs from the entry-level CPU right up to the high-performance CPU for configuring the controller. All CPUs control large quantity structures; several CPUs can work together in a multicomputing configuration to boost performance. Thanks to their high processing speed and deterministic response times, the CPUs enable short machine cycle times.
The different CPUs are distinguished by, for example, work memory, address range, number of connections and execution time. As well as the standard CPUs, there are also two failsafe and three fault-tolerant CPUs available.
With the Version 7 the continuous advancement of the series will be continued. Among others, storage, performance and quantity structure have been innovated. Furthermore the focus was on the new expansion of the Profinet communication performance.
The complementary systems are still the high-end controller for all industries.
Technical data

-
Chemical industry and petrochemicals
Benefit
-
The power of the S7-400 is scalable thanks to a graded range of CPUs; the capacity for I/O is almost unlimited.
-
The power reserves of the CPUs enable new functions to be integrated without further hardware investment, e.g. processing of quality data, user-friendly diagnosis, integration into higher-level MES solutions or high-speed communication via bus systems.
-
The S7-400 can be structured in a modular way; there is a widely varied range of modules available both for centralized configurations and distributed structures. This results in very cost-effective spare parts handling.
-
The configuration of the distributed I/O of the S7-400 can be modified during operation (Configuration in Run). In addition signal modules can be removed and inserted while live (hot swapping).
This makes it very easy to expand the system or replace modules in the event of a fault. -
The storage of the complete project data including symbols and comments on the CPU simplifies service and maintenance calls.
-
Safety engineering and standard automation can be integrated into a single S7-400 controller;
plant availability can be increased through the redundant structure of the S7-400. -
Many of the S7-400 components are also available in a SIPLUS version for external environmental conditions, e.g. extended temperature range (-25 +60°C) and for use where there is aggressive atmosphere/condensation.
-
The high-speed backplane bus of S7-400 ensures efficient linking of central I/O modules
Design and function
The powerful backplane bus of the S7-400 and the DP communication interfaces that can be plugged directly onto the CPU allow the high-performance operation of many communication lines. This permits, for example, the division into one communications line for HMI and programming tasks, one line for high-performance and equidistant motion control components, and one "normal" I/O fieldbus.
Additionally required connections to MES-/ERP systems or the Internet via SIMATIC IT can also be implemented. The S7-400 can be expanded centrally or in a distributed configuration depending on the task. Add-on devices and interface modules are available centrally for this purpose.
Distributed expansion is possible over the PROFIBUS or PROFINET interfaces integrated in the CPUs.
If required, communication processors (CPs) can also be used.
Design
An S7-400 system basically comprises a rack, power supply, and central processing unit. It can be installed and expanded in a modular way. All modules can be positioned freely next to the power supply plugged in on the left. The S7-400 has a rugged design without a fan. Signal modules can be hotswapped. A multi-faceted module range can be used for central expansions as well as for simple configuration of distributed topologies with ET 200.
In a centralized expansion, additional mounting racks are connecteddirect to the central controller.
In addition to the standard mounting racks, aluminum mounting racks with 9 and 18 slots are also available. These aluminum racks are highly resistant to unfavorable environmental conditions, and they are more rigid and around 25% lighter.
Multicomputing
Multicomputing, that is, the simultaneous operation of several CPUs in one S7-400 central controller, offers users different benefits:
-
The overall performance of an S7-400 can be shared by means of multicomputing.
For example, complex tasks in technologies such as open-loop control, computing or communication can be split and assigned to different CPUs. Each CPU is assigned its own, local I/O for this purpose. -
Some tasks can also be disconnected from each other in multicomputing, that is, one CPU processes the time-critical process tasks and another handles the non-time-critical tasks.
In multicomputing operation, all CPUs behave like a single CPU, that is, when one CPU goes to STOP, the others are also halted. The actions of several CPUs can be coordinated selectively by instruction via synchronization calls.In addition, data exchange between the CPUs takes place at an extremely high speed via the "global data" mechanism.
Data/program memory
The size of the work memory is determined CPU that can be selected from a finely graded range of CPUs.The integral load memory (RAM) is sufficient for small to mediumsized programs.
For larger programs, the load memory is enlarged by plugging in RAM or FEPROM memory cards
(64 KB to 64 MB).
Special functions
The S7-400 CPUs have some highly useful special functions:
-
Simpler and faster upgrade due to firmware update via network from an engineering workstation
-
Additional write-protection (for e.g. no component download from PC to CPU) via a system function
-
Optional know-how protection by reading the serial number of the memory card, so that it is ensured that the program runs only with the particular memory card
An integrated data record gateway permits integrated accessto data records across different bus systems and networkboundaries e.g. a control-level PC can communicate via PROFINETwith a lower-level S7-400 controller and the field devicesconnected to it via PROFIBUS.

Technical data
Increase system availability and productivity
Description
The flexible insurance against downtimes
Regardless of the industry, cost pressure and the demand for maximum productivity are ratcheting up automation levels in production plants. This means that economic effectiveness depends directly on the availability of the systems, that is, the automation components used.
To retain productivity, regular maintenance and modernization work needs to be performed through the lifecycle of a plant/machine. For this reason alone, the ideal availability of 100% cannot be attained in practice.
However, with SIMATIC S7-400H, Siemens offers a highly available controller which minimizes the probability of production failures – and thus decisively contributes to maximum productivity.
All innovated CPUs of series -5H have 5 interfaces:
1 PROFINET DP interface
1 MPI-/PROFIBUS DP interface
2 interfaces for sync-modules
1 PROFINET interface with 2-port-switch
All CPUs enables optional Safety and can be used in maximum of 10km distance
between 2 CPUs

Design and function
The SIMATIC S7-400H suitable as a controller for high-availability processes, with two H CPUs of the same type; in the event of a fault, changeover takes place from the master system to the standby station. The method of event-driven synchronization supports fast and bumpless changeover to the redundant CPU in the event of a fault. It resumes processing at the point of interruption without any loss of information or interrupts.All components can be replaced during normal operation (hot swapping). When a CPU is replaced, all the current programs and data are automatically reloaded. The SIMATIC S7-400H is suitable for high-availability processes with hot standby requirements (processes with changeover times shorter than 100 ms).
Design
The central devices can be configured in two different ways:
-
When the subunits have to be completely separated from each other for availability reasons, it is appropriate to use two standard racks (UR1 and UR2). Each rack accommodates one CPU and one power supply (PS). If extremely high availability is required, two redundant power supply modules can be used. The distance between the two racks can be up to 10 km.
-
Two CPUs, each with either a single or a redundant power supply, are plugged into the UR2-H rack with a segmented backplane bus. This supports an extremely compact configuration.
I/O and communication
Maximum availability is not absolutely perfect until it can be matched exactly to your needs. We offer I/O that can be configured and operated redundantly. These modules can be configured in separate racks – or also in the same rack – with a simple or redundant PROFIBUS/PROFINET connection. Maximum availability also applies to communication. Depending on the network topology, redundant connections are created to which it is possible to switch over in the event of a failure. When a failure occurs, fault-tolerant communication is automatically continued without any problems being noticeable to the user.The I/O can be connected to suit the availability requirements.The following types of connection are available:
-
Single-sided connection (normal availability) for all PROFIBUS slaves, e.g. ET 200M, ET 200S, ET 200eco
-
Switched connection (increased availability) for ET 200M
-
Redundant connection (fault-tolerant) for ET 200M. These configurations can also be mixed
These configurations can be mixed.
Engineering
Programming is possible, as in the case of a standard system, in all STEP 7 programming languages. The programs can easily be ported from standard systems to a redundant system and vice-versa. When the program is loaded, it is automatically distributed onto the two redundant CPUs. The functions and configurations specific to redundancy are parameterized using the S7 H-Systems option package (integrated into STEP 7 Version 5.3 or higher). The planning engineer is free to concentrate solely on controlling the process.
Diagnostics / Module replacement
Apart from the standard diagnostic functions, the following functions are also available:
-
With the integrated self-diagnostics functions, the system detects and signals errors before they can affect the process. They enable the faulty components to be identified and replaced quickly which speeds up repairs.
-
All components can be replaced during normal operation (online repair). When a CPU is replaced, all the current programs and data are automatically reloaded. It is also possible to modify the program during normal operation, e.g. changing and reloading function blocks.
-
Changes can also be made to the configuration during normal operation, e.g. adding or removing of DP slaves or modules, changing the memory configuration of the CPU.
