System overview

SIMATIC S7-1200 – Be flexible thanks to networking possibilities

SIMATIC S7-1200 Basic Controllers are the ideal choice when it comes to flexibly and efficiently performing automation tasks in the lower to medium performance range. They feature a comprehensive range of technological functions and integrated IOs as well as an especially compact and space-saving design.

Impressive functionality

Compact size with integrated IOs and modular expansion options

Thanks to extensive expansion options, SIMATIC S7-1200 can be perfectly tailored to the specific automation task.

The integrated PROFINET interface ensures that additional automation components and the TIA Portal engineering framework work perfectly together.

The modular board concept makes it easy to expand the controller without changing the physical size.

Error messages are displayed in plaintext in the TIA Portal on the HMI or web server

Efficient troubleshooting and rapid error localization with the new uniform display concept reduce commissioning times and minimize production downtimes.

SIMATIC S7-1200 offers you a diagnostics functionality that is already integrated in the system with no additional programming required.

Protected CPU access with copy and know-how protection functions

Protection against unauthorized modifications to code or process values requires a higher level of availability in operation. Know-how protection, copy protection, and access protection prevent unauthorized parties from opening or duplicating modules and protect your algorithm and process. These security functions are integrated into the S7-1200 and the TIA Portal.

Failsafe CPUs for standard and safety applications

The failsafe CPU is suitable for standard and failsafe applications in the machine and plant automation.

Safety Integrated provides for a connection to PROFIsafe devices via PROFINET.

In the STEP 7 Safety Basic engineering tool, users create their programs with the same engineering and operating concept for standard and safety-related tasks. 

Technology Integrated: integrated functions and flexible connection of drives

Integrated technology functions for counting and measuring tasks, regulation and motion control make the SIMATIC S7-1200 a versatile system that is perfectly suited for numerous automation tasks.

Thanks to the integrated PID controllers, you can precisely and efficiently adjust physical variables (such as room temperature) to a specific target value.

All CPUs support the trace function. This makes it possible to precisely diagnose and optimize user programs and motion applications.

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.
