Frequently asked questions
What is the replacement for Siemens 6ES7231-0HC00-0XA0?
The S7-200 platform itself is legacy; a migration to the S7-1200 or S7-1500 platform with the corresponding analog input module (e.g., 6ES7231-4HD32-0XB0 for S7-1200) is the typical upgrade path, but this requires a CPU change and rewiring. For a like-for-like spare, the 6ES7231-0HC00-0XA0 remains the direct part.
