The New SIMATIC S7-1200 G2: A Leap Forward in Automation

Siemens has revolutionized its automation offering with the new SIMATIC S7-1200 G2 controller, bringing high-end features to the entry-level segment for the first time in a decade.

Enhanced Processing Power

The G2 stands out with its dramatically improved processing capabilities, featuring a 40-nanosecond bit performance and expanded memory. The 1214C CPU model now packs 250KB of program memory and 750KB of data memory, enabling more sophisticated applications than ever before in a basic controller.

Advanced Motion Control Features

Perhaps most significant is the controller's enhanced motion control capabilities. Users can now control multiple coordinated axes and implement simple kinematics – features previously reserved for advanced controllers, like the more expensive S7-1500 family. This makes the G2 ideal for applications like packaging machines and basic robotics, supporting up to four positioning axes or five synchronized axes.

Innovative Maintenance Solutions

Innovation extends to maintenance and diagnostics through the addition of Near Field Communication (NFC). Technicians can now access diagnostic and operational data wirelessly without powering up the controller, significantly reducing troubleshooting time. The system provides clear, plain-text diagnostic information about the entire PLC station.

Simplified Safety Integration

Safety integration has been simplified with the failsafe versions (CPU 1212FC and CPU 1214FC). Starting with TIA Portal V20, safety programming is included in STEP 7 Basic without requiring a separate license, making safety automation more accessible than ever.

Improved Design and Communication

The physical design has been optimized with a 25% smaller DIN rail footprint and convenient push-in wiring terminals. Communication capabilities now include PROFINET RT and IRT support for up to 31 devices of either type, enabling precise synchronization between components.

With the S7-1200 G2, Siemens has created a future-ready controller that brings advanced capabilities to the basic automation segment while maintaining simplicity and cost-effectiveness. It's a powerful starting point for those beginning their automation journey, with the scalability to grow as needs evolve.
