Siemens announced SIMATIC S7-1200 G2 on June 6, 2024, with market availability planned for winter 2024. Described as the first new generation of the controller in ten years, it is part of the Siemens Xcelerator portfolio and continues standardized engineering in TIA Portal. The update is relevant wherever compact PLCs control machines, manufacturing cells or modular equipment and where performance, safety, motion and transparent data access must grow without moving to an unnecessarily large control platform.
Performance & ScaleThe G2 platform adds processing, memory and communication headroom for more demanding compact-machine projects. |
Motion ControlIntegrated motion functions support coordinated axes and simple kinematic applications within the compact controller class. |
Flexible SafetyFail-safe CPUs and fail-safe I/O allow standard and safety-related automation to be engineered within one platform. |
Data TransparencyNFC diagnostics, the integrated web server and Web API help make operating and diagnostic information easier to access. |
The S7-1200 range combines CPU, integrated I/O, communication and technology functions in a modular compact system. That makes it useful for new machine designs as well as controlled expansion of existing equipment. Engineers can choose standard or fail-safe CPUs and add signal or communication modules according to the verified hardware configuration rather than treating every S7-1200 order as interchangeable.
Siemens states that S7-1200 G2 is not hardware-compatible with modules from the previous S7-1200 generation. Existing programs can often be migrated with engineering adjustments, but the CPU, signal modules, communication modules, terminal and wiring arrangement, firmware and required TIA Portal version must all be checked. For maintenance orders, the complete MLFB is more reliable than a shortened family name.
Send the full order number, CPU designation, power and I/O variant, hardware generation, firmware, quantity and clear label photographs. Also identify the installed signal and communication modules and the engineering software version. These details help procurement and engineering teams distinguish an exact spare from a migration project before quotation.
Use the references below as a starting point for CPU and module inquiries. Confirm the complete MLFB, generation, firmware, quantity and label data before ordering.

No. Siemens identifies G2 as a successor generation, not a hardware drop-in. Review the complete system and migration path.
No. CPU family names can cover different power, I/O and generation variants. Use the complete order number from the label.
Provide the full MLFB, firmware, quantity, label photos and surrounding module list so the requested hardware can be checked before quotation.
