PLC Simatics S7 – 1500

The SIMATIC S7-1500 features a modular design and can be scaled in terms of its functionality.

Different central processing units (CPU types) are available for multiple performance classes. A wide range of signal modules for input and output as well as technology modules for special technological functions, such as counting, and centralized and decentralized communication modules are available to serve as interfaces to the machine or plant. The SIMATIC S7-1500 is approved for protection class IP20 and designed for installation in a control cabinet.

SIMATIC S7-1500 – probably the fastest controller worldwide

You’ll achieve the highest productivity and product quality in your production process by using SIMATIC S7-1500 with its fast backplane bus, PROFINET performance, shortest reaction times, and a command processing time of up to 1 ns in the CPU.

Therefore the PROFINET interface with deterministic time behavior provides reproducibility and precision in the μs timeframe.  

Fast failure detection and correction

Thanks to a uniform display concept, the diagnostics functionality integrated into the SIMATIC S7-1500 system ensures that error messages in TIA Portal on the HMI, in the web server, and on the display of the CPU are visualized identically as plain text information. The configuration and the diagnostic reporting channels are integrated into the system in a user-friendly manner. The trace function is supported on all CPUs.

This makes it possible to run accurate diagnostics on user programs and motion applications and optimize drives. If a fault occurs, the corresponding channel can be quickly identified and precisely assigned. That reduces downtimes and increases plant availability.

Easy handling and installation

The SIMATIC S7-1500 offers the easiest handling and the greatest level of user friendliness in numerous new details. Detailed plain text information offers full plant transparency. The standardized front connector provides simplified spare parts storage. Easy and practical assignment of clamp and label reduces wiring times and facilitates diagnostics in cases of failure.

Integrated potential bridges permit the simple and flexible formation of potential groups, and auxiliary components such as automatic circuit breakers and relays can be mounted quickly and easily. The shielding of analog signals ensures a high quality of signal reception and robustness with regard to external electromagnetic interference. Easy expandability, customized assembly, and upwards compatibility offer maximum cost efficiency and investment security.

Reliable protection of investments and expertise

The security concept of SIMATIC S7-1500 includes measures ranging from authorization stages and block protection to communication integrity. Security Integrated protects your investments, helps prevent the reproduction of machines, and helps to ensure a high level of plant availability.

On the SIMATIC memory card, individual blocks are linked to the serial numbers of the original memory card to prevent program copies. The controller detects modified engineering data or if data is being transmitted from an unauthorized source. Access protection safeguards against unauthorized configuration changes.

Fail-safe control for all functions

What is special about SIMATIC Safety Integrated: It is a system for standard and fail-safe applications. Fail-safe SIMATIC controllers offer the greatest possible integration: one controller, one communication, and one engineering for standard and fail-safe automation.

Safety Integrated applies to all SIMATIC S7-1500 controllers and provides for the simple connection of PROFIsafe devices Geräten via PROFIBUS and PROFINET. With SIMATIC STEP 7 Safety Advanced and in the TIA Portal, users create their programs using the same engineering and operating concept for standard as well as for fail-safe tasks. Data consistency functions automatically synchronize standard and fail-safe program components.

Optimally prepared for all technological tasks

The SIMATIC S7-1500 Advanced controllers are perfectly equipped for technological tasks. Motion Control, signal acquisition and output, and PID control are integrated and can be used in a broader scope with the T-CPUs. The TIA Portal offers support with the engineering of Motion Control tasks such as electronic drives or cam discs.

Siemens offers a coordinated package consisting of the SIMATIC S7-1500 Advanced Controller and the SINAMICS servo drive system, which can easily be linked through the integrated PROFINET interface. The controllers additionally contain compact controllers for continuous or discrete control processes (PID control) in order to provide for simple commissioning and an optimal control quality.

Efficient engineering in the TIA Portal

The Totally Integrated Automation Portal (TIA Portal) provides you with complete access to the entire digitalized automation system, from digital planning to integrated engineering to transparent operation. The new version decreases the time-to-market through a variety of measures including simulation tools, increases the productivity of your plant through additional diagnostic and energy management functions, and offers you greater flexibility thanks to a connection to the management level.

TIA Portal offers flexible cloud solutions, virtual commissioning with a digital twin, coordinated teamwork in interdisciplinary teams, greater transparency, and integrated energy management.
