Modular toolbox

Flexible system offers total scalability

The SIMATIC S7-1500 controller features a modular design and can be scaled in terms of its functionality, so you can adapt assemblies and functions perfectly to suit your machine design. The SIMATIC S7-1500 modules are approved for protection class IP20 and designed for installation in a control cabinet.

SIMATIC S7-1500 CPUs - The heart of the controller system

The central processing units (CPU) are the heart of the SIMATIC S7-1500 PLC. They execute the user program and network the controller with other automation components. Thanks to numerous innovations, the CPUs of the SIMATIC S7-1500 deliver the ultimate plus in productivity and efficiency. 

Further information on the decentralized configurations:

Scalability, performance and usability

The signal modules or peripheral modules of the SIMATIC S7-1500/ET 200MP form the interface between the controller and the process. Via the connected sensors, the controller records the current process status and triggers corresponding reactions of the actuator. The digital and analog modules provide exactly the inputs/outputs that are required for the respective task. They can be used both centrally, i.e. directly at the SIMATIC S7-1500 CPU, and decentrally in the SIMATIC ET 200MP IO system. Analog modules possess expanded functions like oversampling or clock synchronism.

Technology Modules (TM) - The specialists in the system

Technology modules which can be used either centrally in the SIMATIC S7-1500 or decentrally in the SIMATIC ET 200MP IO system offer signal preprocessing close to the hardware for extremely fast counting and measuring as well as precise position detection for incremental and SSI absolute encoders. The intuitive parameterization and efficient programming is done by technology objects in the TIA Portal. A fast reaction to internal or external incidents and counter values is supported by various process alarms. The behavior of the TM modules regarding a "CPU stop" can be parameterized.

More flexibility and performance

Interfaces for communication via PROFINET and in part PROFIBUS DP as well are already integrated in the CPUs. Communication modules increase the communication capabilities of the S7-1500 / ET 200MP providing additional functions or additional interfaces and increase the flexibility and performance of automation solutions with SIMATIC S7-1500 / ET 200MP. Additional interfaces enable realization of complex automation structures or process optimization through connection to the enterprise management level.

Tangible benefits

The ultimate plus for productivity and efficiency

Use the SIMATIC S7-1500 controllers for all aspects of production automation and applications for medium-sized and high-end machines that are demanding in terms of performance, communication, flexibility, and technology.

Perfect interaction between SIMATIC S7-1500 and SIMATIC ET 200MP

The ET 200MP I/O system in protection class IP20 is scalable and is used both as centralized I/O with S7-1500 and in distributed configurations with PROFINET or PROFIBUS. The SIMATIC ET 200MP uses the same assemblies as the central controller for its distributed I/O system.
