Hi Pratapks, not sure to understand what your question meaning , anyway, i found this about self-hosting meaning http://en.wikipedia.org/wiki/Self-hosting "From wikipedia" The term self-hosting was coined to refer to the use of a computer program as part of the toolchain or operating system that produces new versions of that same program—for example, a compiler that can compile its own source code. Self-hosting software is commonplace on personal computers and larger systems. Other programs that are typically self-hosting include kernels, assemblers, and shells. In this case i don't think we can talk about self-hosting because AWL language is interpreted by plc porcessor (not compiled) It's just my opnion Regards |

Hi Pratapks , as well as Mario Bragan... & playerslight already said, the AS system don't need ES or OS for his functionality: it can restart for complete functioanlity when you equiepped in right way (if you are keeping program in RAM memory module remember to check battery backup ). My question is: why you are asking in PCS7 forum instead SIMATIC S7? because PCS7 is a complicate system...well...there is ALWYAS an ES or OS in PCS7 system. Reagrds |
