iulian Posts: 14 Rating: (1)	Communication between S7 315-2DP with CP342-5 and PS with Wincc 6.0 and CP 5612 I have a project with Cpu S7 315-2DP with CP342-5 and PS with Wincc 6.0 and CP 5612. I use S7 protocol via profibus. What parameter most by set in Wincc software in S7 protocol Profibus CP 5612 and Step 7 for communicate with S7 315-2DP via CP342-5. If I connect direct PS with 315-2DP via Profibus work properly (in Wincc communication Profibus CP 5612 I set for communication CPU 315 address). If I connect PS with 315-2DP via CP342-5 Profibus don’t work (in Wincc communication Profibus CP 5612 I set for communication CP342-5 address). Please tell my what I mast do?

J_Bell Posts: 5822 Rating: (411)	Hello iulian, I am not sure, but as far as I remember you have to address the node Address, the PROFIBUS Address, and the location within the Rack you want to connect to, don't you? If so have you addressed the CP or the CPU? If you addressed the CP it will not work because the device you want to connect tois the CPU, as you do it directly to the CPU. So you have to use the Rack 0 Slot 2, for the CPU in the S7-300. Best regards J_Bell

iulian Posts: 14 Rating: (1)	I connect direct with cable CP342-5 and CP 5611 and I set Rack 0 Slot 4 ( slot for CP 342) and address 2 (CPU 315 address ) bat not work. I don’t use 315 for communication because I have 4 cpu 315 (the Profibus 1 from CPU port is busy with ours slaves). The PS most communicate with 4 cpu 315 with Profibus 2 bus via 342.-5 I draw communication . how attach doc file?

J_Bell Posts: 5822 Rating: (411)	Hello iulian, well... think about, which device do you really want to talk to? Does the CP or the CPU run the Program and handle the Memory? [;)] If you are connected to the CP it is OK to use the CP PROFIBUS Address, but you have to set the RACK and SLOT of the CPU instead of the CP, this is my point. Best regards J_Bell

iulian Posts: 14 Rating: (1)	The programs is in CPU. I connect a 270 OP(protool) to cp 342-5 .Communication between cpu 315 and OP via CP 342.5 is OK. When I connect Cpu 315 (Rack 0 Slot 2 addres 3 ) with PC (CP 5611 WinCC ) via Cp342-5(Rack 0 Slot 4 addres 4 ) communication is not ok. I set in WinCC S7 protocol Profibus CP 5611 for communication Rack 0 Slot 4 ( slot for CP 342) and address 3 (CPU 315 address ) bat not work
