Product Brief · January 2003 The most powerful PLC
Introduction The S7-400® is the most powerful PLC in the SIMATIC® Controller family; the range that enables successful automation solutions with Totally Integrated Automation. The S7-400 is an automation platform for system solutions in the manufacturing and process industries, and is distinguished above all by its modularity and performance reserves. Areas of application Application areas are found in · the automobile industry (e.g.
CPU performance There is a graded range of CPUs available for controller design, from the entry-level CPU right up to the high-performance CPU. All CPUs have large quantity structures, and several CPUs can work together in multicomputing configurations in order to boost performance. The CPUs enable short machine cycle times, thanks to their efficient processing speed and deterministic response times. Memory in MB 4.0 3.2 1.6 0.
Integrated interfaces On the other hand, following integration of the DP V1 functions according to IEC 1158 Parts 3-6, new, standardized PROFIBUS DP functions are now also available in the S7-400 for communication with non-Siemens systems. In automation, there is a trend towards distributed systems. The SIMATIC S7-400 supports the required data exchange between distributed systems.
Memory concept, isochrone mode, configuration changes in RUN (CiR) Memory concept All S7-400 CPUs have two types of memory: load memory and main memory. This splitting of the main memory improves performance by around 100 %. While a standard processor accesses its RAM memory at least twice, the special S7-400 processor accesses the code memory and the data memory simultaneously in a single cycle. This is made possible by the separate code and data bus.
S7-400H fault tolerant PLC Based on standard S7-400 modules, the S7-400H is a fault tolerant (redundant) PLC which drastically reduces the risk of production downtime. Its fault tolerant structure makes the S7-400H ideally suited to applications in which MTTR and downtimes need to be reduced or avoided where possible, e.g. for energy generation / distribution, the chemical industry, mining, transport, etc.
S7-400F/FH fail-safe PLC The new SIMATIC S7-400F/FH is an addition to the range of SIMATIC S7 controllers. It is a fail-safe controller based on the technology of the fault tolerant S7-400H. The SIMATIC S7-400F/FH enters a safe state immediately when an error occurs or remains in a safe mode, thus guaranteeing a high level of safety for man, machine, the environment and the process. The S7-400F/FH has a TÜV approval (TÜV = German Technical Inspectorship) and fulfills all relevant standards.

Programming The configuration and programming of the S7-400 is based on STEP® 7. STEP 7 offers functions for every phase of an automation project – from configuration to startup, testing and servicing. Memory requirement STEP 7 STEP 7 incorporates the SIMATIC Manager, the central tool for the software-related handling of the project. This relates not only to a single CPU, but to the whole plant – irrespective of how many controllers, drives and HMI devices the solution consists of.
Communication Totally Integrated Automation A single, completely integrated and consistent system with which you can execute any automation functions! An element of central importance within the system is the communications network: Industrial Ethernet (IEEE 802-3 and 802.3u) – the international standard for area and cell networking – with a connection to the IT environment. S7-400 S7-300® OS Data communication PROFIBUS (IEC 61158/EN 50170) – the international standard for the cell and field levels.
Range of modules In addition to the range of specific S7-400 modules, the S7-400 also gives access to the world of PROFIBUS through the integrated PROFIBUS DP interface. This means that a large number of I/O modules are available with which the S7-400 can be adapted to a wide range of functions. Users of the system have access to PROFIBUS DP modules from Siemens as well as modules from other manufacturers.
I/O modules – Properties Selection guide for digital inputs/outputs Signal modules are the interface between the SIMATIC S7-400 and the process. A wide range of different digital and analog modules provide exactly the right inputs/outputs required for the function in question. However, the S7-400 signal modules represent only a subset of the modules which can be connected to the S7-400 through PROFIBUS DP.
