Hi all, Where can I find the CPU 1500 's safety data (exactly CPU 1513F-1), such as MTTFD, DC, CCF and category or λdu ? Thanks in advance for the help! ------------------------------------------------------------------------------------------ |

hi, MTBF values are also available in the lins in this entry: Mean Time Between Failures (MTBF) - list for SIMATIC products hope this helps, regards, |

Hello FC_CIPEN; The SET team proposes Safety-related data for the Siemens F_CPUs using PFD and PFDh values. For users who would rather have them in MTTFd and DCav format, there are ways to establish a relationship between the 2 sets of data, through specific calculations. An easier way is to use a Safety Calculator, such as Sistema, to do the translation for you. For that purpose, Siemns' SET team proposes a VDMA format library to import CF-CPU data in programs such as Sistema. See the screenshot below. Safety Evaluation Tool offers VDMA 66413 neutral data interface https://support.industry.siemens.com/cs/ww/en/view/109750403 And look at this presentation: ISO 13849-1 PL Calculations Simplified - Robotic Industries AssociationWhen you open the CPU data for a Safety-related configuration, information is provided in terms of PDFh; but you can ask for the same data to be translated to MTTFd, DCav and CCF (depending on the configuration of the Safety function, through the "Determine MTTFd from blocks" selector). Hope this helps, Daniel Chartier |
