http://www.vipa.com/en/home/

no its working for me too 

but some of vipa plc's can be programmed over siemens software 

so i asked in siemens forum rather than google !

the picture show a faked CPU 224XP DC/DC/DC , not a real SIEMENS PLC! (only China copy)

VIPA: Yes some VIPA PLC can programmed with SIEMENS SW but this is not supported from Siemens and no knowledge here published in the Customer Support from SIEMENS.

If you need how to configure the VIPA in Step7 then you must go to the VIPA Support Sites.

Hello amrelhaja;li;

No, Vipa is not property of Siemens; actually, it is now part of the Yaskawa offerings...

I remember the waves that were generated in the Siemens world when the company was founded (originally by ex-Siemens people) in order to propose Siemens S7-compatible I/O modules. There was a very serious breach-of-copyright trial,because they had retro-egineered the backplane communications of the S7, and insisted on using the same part numbers as Siemens for their modules. Siemens lost, and Vipa grew from a Siemens-compatible provider to create their own range of PLCs.

The Siemens vs Vipa copyright trial is discussed in this article:

The chinese module you are showing seems to be somewhat the same story, in another continent. Siemens built a "cheap" version of the s7-200 controllers exclusively for the chinese market (the infamous S7-200CN), about 10 years ago. It seems to now have been hacked and copied by many chinese manufacturers, using the same faceplates and part numbers (generally with much cheaper components, though). See thislink to show you how many clones ypu can find in a single page:
