I think I need the P-BUS information to control the I/O card ?
and also Backplane bus in S7-300 and S7-400 |

Hello AmirAlwaled I'd say you can rest assured that the backplane P-bus (I/O bus) protocol is Siemens propietary and also that there are differences between the S7-300 and 400 at least as far a thebackplane K-bus (communication bus) is concerned (none of which will make your task any easier I'm afraid). One additonal pointer I can give you though is to read Decinteresting research into this subject in the thread informations about backplane (S7 300 related). While this, together with the other info you found, may give you enough starting points to do the reverse engineering of the backplane protocol, you will still have your work cut out for yourself. Saying that, "value added third party" modules from other companies do exist (e.g. Helmholz offers CAN bus modules for the S7-300 which don't exist inthe Siemens portfolio) and these companieswould have the knowledge of the backplane protocol and may (but possiblymay not) be willing to share it. My question to you is though: Is it a must have that you hook your product/module onto the S7 backplane? It may not only be easier, but would possibly also open you development to a wider market, if you instead develop it as a standalone module withlet's say Profibus or Profinet interface (which are open andwell documented interfaces). Food for thought anyhow and I hopeit helps. |

That is right .But I prefer the hard way
It's a great post from Dec I should PM him thanks fritz.
I have already communicated with VIPA but "Frau Kuefner" transferred me twice to egyption sales partner so I will wait until "Willi Heintz" VIPA Vice President back to his office in 17 october. I will tray to counicte with ILStechnology that devolop " Siemens CP 343-1 ERPC " . and you have add Helmholz to my list thank you again .
Yes you are completely right. but I am developing it first " for fun" second for student to use WinAC with Siemens Rack 300 without ET200 module, then we should develop our WinAC Software under windows, then we should customise linux to be controller OS(operating system) . For example there is aggregate Servers from HP called " HP Blade ". We have four of them each are 2 Xeon processors 2.4 GHz 8 cores each, 24 G ram,10 G NIC , with great redundant ,HP 4400 Enterprise Virtual Array,HP SAN Switch, Cisco Core switches , Symantec Backup Exec System Recovery , But we can't use it with WinAC because there is no CP1616 for Mezzanine interface . |
