S7-200 that supports MPI

Hi everyone,

This is probably a dumb question (but I'm not that experienced with Siemens systems). One of our customers claims that there exists S7-200 CPU's that support MPI? We are interested in buying such a CPU (it should have a RTC as well). Any thoughts? Which CPU supports both MPI and RTC?

Thanks!

As far as I know, all second generation S7-200s (S7-22X) are capable of communicating over MPI and have a RTC on board. S7-22X can however only act as a slave on an MPI network, so you'll need at least one S7-300 to take on the role of master on the network.


Kind regards,

I am not positive but S7-200 could do peer-peer with PPI and I think it can with MPI, I know there are some limits to the connections available. Another option as a master is a TD-200, of course a PC with MicroWin will be a master.

Check out the manuals etc from the support site: http://support.automation.siemens.com/US/llisapi.dll?csquery0=MPI&aktprim=0&caller=view&extranet=standard&func=cslib.csinfo&lang=en&nodeid0=10805149&objaction=csbrowse&objid=10805149&siteid=cseus&subtype=130000

As above the 200 needs to be a slave:-
