Hello Sir I am a new to use Seimens PLCs. I want to use ET 200 module 6ES7 153-2BA00-0XB0 with CPU 315 2PN DP. I make hardware configurations as attached PICs. download program it shows BF red indication. also when the CPU 315 also indicates SF and BF. when i reset the CPU both indications run out ,but when ever i run the program SF and BF indications come. ------------------------------------------------------------------------------------------ |

Is there any addressing problem |

Check the diagnostics buffer of the PLC, it will tell you what the problem is. |

Hello ihsei; BF indicates a Bus Fault, meaning the CPU master cannot see the configured IM modules; possibly there is an address mismatch.between the dipswitches on the IM 153-2 module and the configuration of your network. See the attachment below, taken from the ET 200M Operating Instructions manual https://support.industry.siemens.com/cs/us/en/view/1142798 SF means a System Fault, which can be a general hardware or software fault; however, in combination with an active BF LED, it generally relates to your program requesting a link to an address that annot be reached (because of the Bus Fault). Start by determining if there is a Profibus address mismatch in your system, and correct it (preferably on the IM 153-2 dpswitches). See if the SF LED goes out at the same time as the BF. If it is still active, open your CPU's diagnostic buffer (CTRL+D, in Simatic Manager) to read the messages logged that can indicate the cause of the fault. Hope this helps, Daniel Chartier |

Helllo ihsei908, do you adjust the right address at the IM153-2 (DIP-switch)?
