SIMATIC S7-400 PLC

Link to the Latest S7-400 Information

The S7-400 is the most powerful PLC in the SIMATIC Controller family designed for large applications with high performance . It enables successful automation solutions with Totally Integrated Automation (TIA). The S7-400 is an automation platform for system solutions in production engineering and process engineering, and it stands out above all for its modularity and special performance reserves.

Fast processing speeds of 0.1 µs per instruction.

Large memory , up to 64 Mbyte with memory card.

Extensive I/O , up to 65536 Digital I/O and 8192 Analog I/O can be achieved with a wide range of central and distributed digital / analog expansion modules. Failsafe I/O is achieved with ET200 Remote stations with Safety Integrated signal modules

Special Function Modules , such as High Speed Counters, Electronic Cams, Positioning Modules for Stepper and Servo Motors, Closed Loop Modules for PID control loops,

Totally Integrated Automation through: MPI (Master/Slave), PtP-serial, Modbus (Master/Slave), Data Highway, Profibus (Master/Slave), Industrial Ethernet, Web-server, and Modem connectivity with Teleservice.

Modularity

An outstanding feature of the S7-400 is its modularity. The powerful backplane bus of the S7-400 and the communications interfaces that can be plugged direct into the CPU allow high-performance operation of a large number of communications lines. This enables, for example, subdivision into one communications line for HMI and programming tasks, one for high-performance motion control components, and one "normal" I/O fieldbus. Additionally required connections to MES/ERP systems or to the Internet can also be implemented.

Engineering and diagnostics

The S7-400 achieves extremely efficient configuring and programming in conjunction with the SIMATIC Engineering Tools, especially in the case of extensive automation solutions with a larger engineering component. Examples of this are high-level languages such as SCL and graphical Engineering Tools for sequential controls, state diagrams, and technology-oriented diagrams. Storage of all the project data including symbols and comments on the CPU makes service and maintenance work much easier.
In addition, powerful integrated system diagnostics functions guarantee higher controller availability and therefore also higher productivity. On top of this, you have configurable process diagnostics functions for analyzing process faults, reducing downtimes, and further increasing productivity.

Graded CPU range

There is a graded range of CPUs for configuring the controller: from the entry-level device right up to the high-performance model. All CPUs have large quantity structures and possess integral standard interfaces. Several CPUs can work together in multi-computing for even more performance power. The effective processing speed and deterministic response times of the CPU's enable extremely short machine cycle times

Deterministic features

The large performance reserves guarantee deterministic response times even when communication tasks or other unforeseen loads have to be handled at the same time

Special applications? No problem.

There are further product versions based on the S7-400 for precisely this purpose:

Fault-tolerant applications can be implemented with the S7-400H

For failsafe applications, there is the S7-400F that is also available in a fault-tolerant version

There are S7-400 CPUs as PC plug-in cards for PC-based solutions

Human machine interfacing and diagnostics on the Internet? SIMATIC S7-400 makes it possible. It only takes a CPU and the CP443-1 IT communications processor to open the door to the IT world.
