where can get V3 of the library?

Hi, I think I have the same issue as the owner of this thread. The difference is that I have WP321, specifically option 1. My PLC has firmware V3.0, and the Siwarex library says CPU_V4.

You mentioned that I can use version V3 of the library, but where can I get it?

Best regards.

Hello msgsadek,

Well, you use in your TIA project:

- a PLC with the firmware V3.0

- the FB231 with the version V4.1

This combination doesn’t work!

You have two possibilities:

1. possibility:

For your older PLC with the firmware V3.0, you use the FB231 with the version V3.0 (= without Siwarex DB)

2. possibility:

You use a PLC with the firmware V4.x.

If so, you can use your FB231 with the version V4.1 (= with Siwarex DB)

Best regards

Siwarexi
