Hi all, 

Anybody know where I can find the 'total list of TUV approved Safety blocks' ??

I think i have seen as .PDF Document  (??) but now not sure if this thing is really available becoz I cannot find on the website.

If any body knows kindly provide me a link.

Thanks in advance

Hello sunny;

This linnk opens up the TUV annex 1 to Certification of the Simatic Safety Systems, which lists the certified CPUs, instructions and safety blocks recognized by TUV:

This link is mentionned in the Simatic Safety- Configuring and programming manual:

Compliance of the system library elements used in the safety program with Annex 1 of the Report for the TÜV certificate

Introduction

The STEP 7 Safety optional package contains LAD/FBD instructions for programming of your safety program as well as F-system blocks that have been created and tested by SIEMENS and certified by TÜV for creating an executable safety program. In the process, the F-system blocks used are automatically defined by the F-system based on the set safety system version (see section"Settings" area).

To allow you to check whether the used versioned LAD/FBD instructions and F-system blocks correspond to Annex 1 of the Report for the TÜV certificate and to the versions you intend to use, these are listed in the safety summary.

Procedure

To check, download the current Annex 1 of the report for the TÜV certificate "SIMATIC Safety" from theInternet.

Hope this helps,

Daniel Chartier
