I'm not very good at programming PLCs and i have one problem if someone could help me. I have CPU 315-2 PN/DP with 3 modules for I/O signals, and at slot 7 i have CP 342-5. On CPU 315 the MPI/DP interface (X1) is broken and PLC cant send information on SCADA program. Could i send information through CP 342-5 on SCADA? Do i need DP_SEND and DP_REC functions defined in program block of CPU 315-2? Should I make slave/master on CP 342-5? Communication with SCADA is through Profibus DP. Hope that you guys could give me some advice where to start... Attachment hardwere setup.PNG (49 Downloads)

Update: here is some example about CP342-5 as Master (Step7 v5.x), you can check infos there to better understand some problematic (link): S7-300 CP 342-5 Profibus Master Example In other case you can use search box on upper right side of this page for find some other examples.

That means, right rack and slot position of CP 342-5. Thanks you guys for yours suggests. THOMPSONvk
