Lead: Siemens announced the S7-1200 series transition. First-gen S7-1200 will be discontinued on Nov 1, 2026. S7-1200 G2 is its successor with better performance and web functions.

01 Official Discontinuation Date

Siemens sets Nov 1, 2026 as the PM400 milestone. It covers 1212C,1212FC,1214C,1214FC first-gen CPUs. Production will stop gradually. Plan spare parts in advance. Official migration guides and cross-reference numbers are available.

02 S7-1200 G2 Core Advantages

S7-1200 G2 replaces the original S7-1200 for modern automation.

• Models:1212C G2,1214C G2,1215C G2,1217C G2 and FC failsafe versions
• Built-in OPC UA for IT/OT integration and cloud data transfer
• New web server with WebAPI for simple remote monitoring
• Retain PTO interfaces for positioning and motion control

03 Final Firmware V4.6.1 for First-Gen

Siemens released V4.6.1 in Sep 2025. This is the last maintenance update. V4.6.0 expanded CPU work memory. V4.6.1 fixes OB execution priority and CP data receiving after faults. Upgrade to V4.6.1 to stabilize your production lines.

04 TIA Portal Version Requirement

S7-1200 G2 needs TIA Portal V20 or above. TIA Portal V21 is recommended for full stable configuration. You can migrate old S7-1200 projects to G2. Most codes and variables can be reused.

05 Transition Timeline

• 2025-09: Final firmware V4.6.1 release for first-gen S7-1200
• 2026-11-01: PM400 discontinuation announcement for first generation
• Ongoing: Supply of S7-1200 G2 and migration technical support

06 Migration & Selection Tips

New projects: Choose S7-1200 G2 directly, such as 6ES7214-1AH50-0XB0 (1214C G2). Existing projects: Assess spare stock before Nov 2026. Migrate step by step to reduce downtime. Safety projects: Pick FC G2 models to keep safety function consistent. Cloud/OPC UA demands: Select G2 version.

07 Impacts for Different Users

OEM & machine builders: G2 supports OPC UA and web diagnostics to raise machine value. System integrators: Master migration service and prepare TIA Portal V21 early. End users: Stock spare parts during transition period to avoid equipment shutdown.
