SIMATIC S5 3rd party programming environments

[EirikV 1]

Hi, I read on Wikipedia that there allegedly exists several third party programming environments for SIMATIC S5, even a C cross-compiler. Does anyone know where I can get my hands on this? Would be nice to experiment with!

Yes there are several alternatives for the Siemens Step 5 software. PG95/PG2000 at www.process-informatik.de Accon PG at http://www.classicautomation.com/STEP-5-Alternative.aspx IBH Softec at http://www.ibhsoftec.de Win-SPS at http://www.mhj-software.com/de/ Most offer a free demo download

I dont think there were ever a "C compiler" for S5. I think there was the precursor to SCL, which is a Pascal like language for S7. Are you writing a history book about S5 ? Could be interesting. Surely you are not wasting any time on S5 with a view to actually make new programs to run on it ;)

Hehe, no I'm not writing a history book :) It was more out of curiosity, I kind of have a fascination for these old, obsolete monoliths. Besides, there are lots of them in my area, so a little more knowledge about them could probalby be nice when I'm running around trying to figure out what went wrong! :)
