Can Libnodave be used to enable communication of PC (with MPI PC-Adapter cable 6ES7 972-0CA23-0XAC) with 6 PLC's S7-226. The PLC's are connected with PC via communication modules EM-277.
Thanks.

I don't whether the PC-Adapter cable 6ES7 972-0CA23-0XAC can be used with S7-200 at all. I thought it cannot. But if it could be used in principle, there is certainly no way to initialize the adapter for anything else than MPI/Profibus in Libnodave :-(
Next I don't know what the EM277 does. Does it provide a programmer port?
Do you want to replace the EM277 by a PPI network?

EM-277 is galvanically isolated MPI/PROFIBUS Slave Card. I need to use it because it provides the galvanical insulation, oppositely to Port0 and Port1.

Also, I don't intend to use it for programming, but to design HMI between PC and network of 6 PLC's S7-200.
