Hello Swami_GS, there are no special GSD files for redundant systems. regards |

Gents, I too am configuring PAC3200 meter to S7-400 PLC over profinet. A link to the GSDML file is below: GSDML-File: Switched Ethernet PROFINET Module http://support.automation.siemens.com/WW/view/en/59840946 I can ping the PAC3200 meter when wired in to the 'ethernet' port but not when wired in to the 'profinet' port. Using the PAC3200 meters menu structure the ethernet type and address can be configured but doesn't seem to have any Profinet configuration. Is there a tool/software required to setup the profinet expansion module? If not, perhaps the Profinet plug in module to the PAC3200 is faulty. May need to try a different one of the same type. Using the GSDML file is useful as you can drag and drop power meter parameters in HW config to assign "I" addresses to them. Have you experienced this profinet behaviour before? |

Hello Swami_GS I'm afraid to say that the PAC's do NOT (yet) support Profinet System Redundancy. System Redundancy means that there is a logical connection of IO devices via Profinet with a each of the two H-CPUs. Your PAC's will belong to only one of your H-CPU's (so called one-sided I/O's). As long as that CPU is up and running (irrespective if it currently runs as the Master or Standby CPU), the PAC data is available to both CPU's,if you loose that CPU though, you'll also loose the PAC I/O's. Possibly not the answer you were hoping for, but I hope ithelps anyhow |

That is correct dear Swami_GS the PAC's are one-sided I/O's and communicate only with the CPU in which you have configured them. As long as that CPU is up and running, the PAC I/O data is though also available to the partner H-CPU. See also chapter 13.2 of the SIMATIC Fault-tolerant systems S7-400H manual for more on the ramifications of using one-sided I/O's in a H Systemand chapter 8 for things concerning Profinet I/O's. Having the PAC's in anMRP ring does NOT change any of this, it does though provide you with a greater availability of the physical connection. |
