With the SIMATIC S7-1200 G2, Siemens introduces a new generation of compact programmable logic controllers (PLCs) that meet these requirements precisely.
More automation in less space
Compared to previous S7-1200 models, the S7-1200 G2 family offers significantly greater computing power and memory capacity, as well as improved communication options, all without taking up significantly more space in the control cabinet. This enables more demanding automation tasks to be realised.
- A higher clock speed and faster program execution ensure quicker response times.
- Larger program and data memory enables more extensive projects.
- The compact design allows for modular expansion via signal boards or modules.

| SB/CB | 38 × 62 × 21 mm | SB/CB | 15 × 62 × 63 mm |
Integrated motion control and safety
The S7-1200 G2 supports motion control functions directly in the controller, ranging from single axes to coordinated movements via PROFINET IRT. This makes it suitable for basic motion tasks without the need for additional motion hardware. In addition, safety functions can be integrated into many applications. Certain CPU variants (e.g. those with ‘FC’ = failsafe) support functional safety in conjunction with safety I/O modules.
Secure communication and diagnostics
Network and data security form an integral part of the S7-1200 G2 architecture:
- It supports modern encrypted communication for secure data transmission (e.g. TLS for specific services).
- With NFC (Near Field Communication), diagnostic and operating data can be read out contactlessly directly on site, which is practical for maintenance and troubleshooting.
Scalable engineering with TIA Portal
From version V20 onwards, the parameterisation, configuration and diagnosis of the S7-1200 G2 is carried out in the TIA Portal. A common engineering environment is used for standard and safety functions.
- Projects can be set up in a standardised manner and transferred to larger SIMATIC systems as required.
- Integrated libraries support motion and safety functions in the development process, for example.
Practical modules and extensions
The S7-1200 G2 family includes various CPUs with integrated I/O and extension options:
- CPUs with 8 to 14 digital inputs/outputs.
- These can be expanded via signal boards or signal modules for additional digital/analogue channels.
- There is also a pluggable memory card for programme uploads, firmware updates, and long-term measurements.
The smart choice for compact automation
The SIMATIC S7-1200 G2 from Siemens is a compact and powerful PLC that is ideal for classic automation tasks, basic motion control and flexible safety. Thanks to standardised engineering and modern communication and diagnostic functions, it provides a solid foundation for efficient automation solutions in small and medium-sized machine environments.
