CPM series as well as the older C series models cannot use "inline" rising ? or falling edge ? contacts, this is only supported by the newer models (CS,CJ,CP). For this you need to use the Differentiate Up/Down (DIFU and DIFD) instructions. Basically your edge condition fires the instruction, and the address number entered for the DIFU or DIFD can be used elsewhere in your ladder as the edge contact.
