Adding Siwarex Cards (WP 251 & FTA) to TIA Portal V15.1

You are right to note the difficulty in directly finding HSPs for Siwarex cards in TIA Portal V15.1. Here's how to proceed:

1. HSP Availability: Official HSPs for older Siwarex cards (like WP 251 and FTA) are often not available for the latest TIA Portal versions (V15.1).
2. Using Older TIA Portal Version: The recommended approach is often to use a TIA Portal version for which the HSP is available (e.g., V13/V14). Configure the Siwarex cards in that version, and then archive the project.
3. Import into V15.1: Import the archived project into TIA Portal V15.1. The Siwarex cards should be recognized, but you may lose some newer V15.1 features for those specific cards.
4. Siemens Support & SiePortal: Check SiePortal for relevant FAQs, HSP downloads for older TIA Portal versions, and potential workarounds. Search specifically for your card (WP 251 or FTA) and the older TIA Portal versions.
5. Consider Newer Alternatives: If possible, evaluate migrating to newer Siemens weighing technology that has native TIA Portal V15.1 support.

Important Note: Compatibility can be complex. Thoroughly test your configuration after importing into V15.1.
