The smart choice for basic automation
As technological advances put greater pressure on industry and machine building, the need for smart, efficient and reliable automation has never been more critical: more productivity, scalable and tailored solutions, and stringent legal regulations — without compromising efficiency. The SIMATIC S7-1200 G2 rises to these challenges.
S7-1200 G2 controllers combine integrated I/Os, communication and technology functions in a space-saving design for automation tasks in the low to medium performance range — available in standard and fail-safe versions.

Featured capabilities

Enhanced performance & scalability
Powerful processing, dedicated communication performance and expanded memory for faster data processing and more multitasking — higher productivity and complex motion handled seamlessly. Standardised engineering in TIA Portal lets you scale as required.

Flexible machine safety
Cost-effective, scalable fail-safe solutions for safe machine operation. The optimised fail-safe portfolio meets legal safety requirements without compromising productivity; PROFIsafe devices connect via PROFINET.

Efficient motion control
Precise, reliable control of single axes, coordinated axes and simple kinematics, with integrated technology objects and PLCopen standard functions.

Increased data transparency
Wireless access to diagnostic and device data via NFC and a mobile app, an integrated web server and Web API — better monitoring, faster analysis and less downtime.
Integrated in TIA Portal, built for every machine
The scalable S7-1200 G2 controllers have integrated inputs and outputs plus communication options, and are modularly expandable with digital and analog I/O and communication modules. Integrated technology — high-speed counters, pulse-width modulation and pulse-train outputs — covers temperature control, pump and fan control, conveyor technology and packaging machines.

Already using the SIMATIC S7-1200?
S7-1200 G2 is not hardware-compatible with the previous S7-1200 family, but existing PLC programs can typically be converted with only minor adjustments. Brandco engineers the complete migration — hardware selection, program conversion in TIA Portal, panel modification, testing and commissioning.

S7-1200 G2 inside a complete solution
As Siemens technology partners we select, program and commission S7-1200 G2 controllers inside our automation and drive control panels — together with SINAMICS drives, HMI and SCADA — as one tested system from one team, with 24×7 support afterwards. Our TIA training institute also offers hands-on S7-1200 G2 training.
