Hello everyone,

I am facing an issue adding a new SM 1231 AI 8 x RTD module to my project in TIA Portal V20 and would appreciate your guidance.

**The Problem:**

The physical module I have is:

*   **Article Number:** 6ES7 231-5PF32-0XB0

*   **Module:** SM 1231 AI 8 x RTD

*   **Hardware Revision:** 6

*   **Firmware Version:** V2.1

*   **Manufacturing Date:** 03.2025

However, in my TIA Portal V20 Hardware Catalog, the highest options available for this module are only up to **Hardware Revision 5 / Firmware V2.0**. I cannot select the correct version for my module.

**What I have tried so far:**

1.  I have already installed the latest available update for my TIA Portal version: **TIA Portal V20 Update 3**.

2.  I have also updated all Hardware Support Packages (HSPs) to their latest versions.

Despite these steps, the Hardware Revision 6 does not appear in the list.

**My Question:**

Is there something else I need to do to make Hardware Revision 6 appear in the catalog? Has anyone successfully configured this specific hardware revision in TIA Portal V20?

Thank you in advance for your help.

**Best regards,**

Maxi
