Hello ssantiago, hello Tala it appears that there is a mismatch concerning the CP342-5 DP Slaves I/O config that theDP Master expects to "see" (done in HWconfig of the DP master CPU) and the one that is actually configured for the CP342-5 (done via the setup of DP_Send/DP_RECV calls and related DB's). Its hard to say what is exactly wrong without looking at your S7 projects (pelase upload them). For now I adda couple oflinks which have more on the matter and there's plenty more info to be found on the subject of CP342-5 with a search at https://support.automation.siemens.com: What are the differences between an integrated DP interface of my CPU (e.g. CPU 315-2 DP) and the DP interface of the CP 342-5? What master/slave communication options are available on PROFIBUS DP? I hope this helps |
Cheers |

Attached is the program of Salve Node connested with CP 342-5, please chwck wether the configuration is correct or not, the Bus Fault is blinking on the CP 342-5. the profibus address is 5 in the CP 342-5 but in the HMI it shows profibus DP address = 100, there is one screen which shows the profibus address. I downloaded the HW configuration several times but its still showing hundred there but when I upload the program from the PLC it shows me the Profibus Address of CP 342-5 = 5, The Diagnostic Buffer is syaing that the Mastre and Slave configuration mismatch. The Master DP program is attached in the next post.

The attached program is the S7 300 Master DP, there are several nodes in the HW configuration the one which is not working is node 5. When I check the Diagnostics of this node its saying that, DP slave not available.
