Take control of communication
Communication modules increase the versatility of SIMATIC S7-1200 offering several open communication protocols as serial communication, PROFIBUS, IO-Link, AS‑Interface, PROFINET, Industrial Ethernet, Telecontrol as well as innovative vertical and horizontal protocols as MQTT and OPC UA providing massive storage and data analisis system possibilities. Those attributes are the best foundation for digitalization and are the drivers of new applications and business models such as predictive maintenance or machine learning.
Protection concept for the controller
The security concept of SIMATIC S7-1200 includes communication integrity. Security Integrated protects your investments, helps prevent the reproduction of machines, and helps to ensure a high level of plant availability.
Highest machine safety
One system for standard and fail-safe applications: One controller, one communication system, and one engineering environment for standard and fail-safe automation. Safety Integrated means the easy connection of PROFIsafe devices via PROFIBUS and PROFINET, and data consistency between standard and fail-safe program components. It offers support for mixed option using fail-safe and standard I/O assemblies.
Ready for the digitalization
SIMATIC S7-1200 has technological integrated functions such as HSC, PTO/PWM and Motion Control.
The vision of intelligent data analysis
Collecting, analyzing, processing and forwarding data in an automation system is becoming increasingly important. Based on SIMATIC Industrial OS, a multifunctional controller platform and Industrial Edge devices are already prepared today for these applications at the control level. They are connected via Ethernet and can be scaled for use with any SIMATIC S7-1200 CPU. These devices combine the advantages of a cloud with the strengths of a local solution and enable different data acquisition and optimization concepts: local, cloud-based and hybrid.
Individually expandable
SIMATIC S7-1200 has dedicated modules which increase the CPU added value offering specific automation tasks:
- Energy Meter Condition Monitoring System CMS Weighing systems SIWAREX

The SIMATIC S7-1200 modules at a glance
The S7-1200 controller is designed as a compact CPU, which means that IOs are already integrated. Yet the S7-1200 station can be equipped with additional IO modules to enlarge the capabilities of the PLC.


SIMATIC S7-1200 CPUs
The modular SIMATIC S7-1200 controller is at the core of our offering for simple but highly precise automation tasks. The SIMATIC S7-1200 controller is modular and compact, versatile, a secure investment, and is perfectly suited to a whole range of applications.

SIMATIC S7-1200 Signal modules
The central processing units of the SIMATIC S7-1200 PLC are designed as Compact CPUs with integrated I/Os. Their modular design can be used to increase the configuration limits or to adapt the controller to new tasks: through mounting a Signal Board on the CPU or adding separate signal modules.

SIMATIC S7-1200 Special modules
Special modules enhance the application area of the whole system, e.g. for Codition Monitoring, integrated weighing technology, simulation of input signal or for extending the power reserve for the S7-1200 real-time clock by an additional battery board.
SIMATIC S7-1200 Communication modules
Communication modules increase the communication capabilities of the SIMATIC S7-1200 PLC through additional functions and interfaces. S7-1200 communication modules support serial communication, PROFIBUS, IO-Link, AS-Interface and several mobile standards.
