All CPUs S7-22x can be used as slaves on an MPI network. The following FAQ will show you how to connect a S7-22x to a S7-300 master over MPI, how to setup MicroWin and how to program the XPUT and XGET ffunctions in the S7-300 master, with a small example. http://support.automation.siemens.com/WW/view/en/747743 Hope this helps, Daniel Chartier

	Best regards, Darius
