simatic microbox 427B-RTX

I need to troubleshoot a bottle blowing machine which has a simatic microbox 427B-RTX.
Is it the same thing as connecting to S7-300 or there is something I should be aware of.
Thanks.

Hello rachiahi;

Even though the WinAC RTX system has been discontinued for almost 15 years, there are still documents available describing the Win AC RTX system on the forum, you can locate them using the Search box at the right of this page (filter with the Knowledge Base).

One of those documents is found here:

https://support.industry.siemens.com/cs/ca/en/view/7216008

In the introductory pages, it describes the constituant parts of a WinAC RTX system, which includes a version of Step 7 and WinCC. The exact version will depend on the specific version of your WinAC RTX system, and they will run under Windows NT 4.0.

Hope this helps,

Daniel Chartier

Thank you Daniel.
