Hello, please find attachment. It shows my system configuration. Here my 300 plc is connected to field I/Os over profibus network & CP 342-5 card is act as a slave connected via y-link to 400 system over optical fiber network. I have done all programming which is required for this communication. My questions is how much maximum data can be tranferred between 400H master station & 300 plc through CP 342-5 profibus CP card using fiber optical network.??? regrds, manoj AttachmentSYSTEM_CONFIG.pdf (303 Downloads) |

Hello Manoj; When you are using a CP 342-5, you cannot use the DPWR_DAT and DPRD_DAT unctions (SC 15/14), you must use the DP_SEND and DP_RCV (FC 1 and FC2) functions dediacted to the CP 342-5. You will find basic information and examples in the following links: How do you configure an S7-300 CPU or a CP342-5 as DP slave to an S7-400H as DP master using a Y-link? Why does my CP 342-5, operating as a DP master or DP slave, not switch to data transfer, even though the CPU is in RUN mode?

Hello, Please find attachment. As per this siemens's support manual, I have done all the procedure. These SFC 14 & 15, I am using in master PLC. FC 1 & 2 are using in slave plc to read & write data from CP 342-5. Shall i use FC 1 & 2 at both end?? I am not able to establish communication more than 64 byte Total consistency IN & OUT. What is total & 1 byte consistency?? Thank you for reply. regards, manoj AttachmentDP_Slave_on_H_System.pdf (207 Downloads) |
