Hello Navang, Until Krish gives an answer.Please take a look at Y-Link manual. In page 165, 12.2 Diagnostics with STEP 7: IM 153-2 Diagnostic interrupt If a DPV0 slave or a non-interrupt-capable DPV1 slave on the underlying master system reports a diagnosis, the IM 153-2 initiates a diagnostic interrupt on the higher level DP master system ("proxy diagnostic interrupt").The diagnostic frame of the slave is stored in the additional interrupt information. If this frame is longer than 59 bytes, the information exceeding the 60th byte is discarded. In addition to this, bit 7.(Ext_Diag_Overflow) is set in the third forwarded byte (byte x+6). The diagnosis of an interrupt-capable DPV1 slave operated in DPV1 mode does not cause a diagnostic interrupt.In page 166, 12.2.4 Example of a diagnosis in redundant mode (Using SFC13) |

Hi All I had asked this from SIMATIC Technical Support. I am sharing their reply for the benefit of all concerened : ----------------- It Is possible by using the block sfc 58 ,sfc 59 ,sfc 52,sfc 53. and also use link better diagnostic feature http://support.automation.siemens.com/WW/view/en/387257 ----------------- Thanks & Best Regards Navnag |
There is no such thing as the last bug in a program |

Hello Navang, Thanks for the feedback regarding diagnostics. I hope you will give us feedback on how you will configure and parameterize ET200S under Y-Link (DPV0 or DPV1) About FB125, I'm not sure it will show you slaves under Y-Link. the DP Master system of the Y-coupler always have 5980 or above and I don't believe this number would fit as a parameter for FB125 (You have to check it). So, FB125 will tell you about DP slaves connected directly to the upper DP masters which means you will have your Y link (IM153-2)displayed just as a single slave (No slaves behind). Now, I'm having doubts whether you have to switch DP MASTERSYSTEM parameter of FB125 according to which CPU is master or not. Takea look at this thread. Best regards. H-H |

Dear Krish, Thank you very much for your feedback. I was really astonished that there's a dedicated function in PCS7 (I have quite limited knowledge of PCS7 I've read its description and it's really good. Thanks again for such info and such help. Dear Navang, I've tried to configure the ET200S standard and HF interface module behind IM153-2 based Y-Link and no use. I still can't mark Operation at preset <>actual configuration. The only way I could enable such feature and also to enable Replace module during operation was to use the inserted DPV0 GSD file. Do you mind if you upload your sample configuration so I can figure out what's wrong with mine? Since I'm still interested in such configuration (Y-Link with ET200S) I read more on the FB125 and found out that the S7-400 H CPUs are not listed in application area of FB125. Best regards.
