Hello everybody. I spend hours struggling to solve the problem without results, so maybe here is somebody who had simillar situation to mine. Problem is with CPU 410-5H in redundant mode. Here is the problem: After power off and then power on both CPUs, cannot go to RUN mode. Both CPUs have STOP light active and RUN light blinking all the time and cannot go to RUN. It takes more than 15 minutes and nothing... Here is what I tried: - clear both CPUs (by taking out batteries) - download hardware, netpro and cfc to the first CPU, start the first, go to RUN and start second one to synchronize with the first. - after that both CPUs work correctly, redundancy work ok, switching one of them causes the second one takes master function and vice versa. - But when I power off both CPUs and power on both again situation looks the same. Both CPUs have STOP light active and RUN light blinking all the time and cannot go to RUN. Is there anybody who had simillar problem? In attachment there are screenshots from problem I found and diagnostic logs. I found problem could be because of OB82 and OB83. But how to solve this.

Hi hdhosseini, thank you for your response. I took out batteries only in case to reset whole CPU (to make it completely blank). Ater that I put batteries again and re-loaded whole configuration and cfc again. Then I put program to RUN mode. After power off both CPUs situation is the same when I power on. I checked both OB82, and 83 and are in the tasklist. I have another clue, maybe the reason could be because of wrong settings in H Parameters (monitoring times). This configuration uses F modules and therefore "use only calculated values" must be unchecked. My program is in OB35 (100ms) and safety program in OB36 (100ms). Maybe these four times are wrong calculated according to my program. AttachmentCPU.zip (212 Downloads) |

I will do this when I go to the plant and have this diagnostic buffer separately for each CPU. Then maybe we will find the solution. |

When you post your Diagnostic Buffer, you will be able to see the Firmware Version of the CPUs. You will want to look at the available Firmware Versions to see if the Firmware update will fix your issue. The 410 Operating System's can be downloaded here, https://support.industry.siemens.com/cs/ww/en/view/109476571 |

After power off and then power on, the 410 CPU makes a self-diagnosis, which takes 20 minutes and more.

Standard pass, I would check to make sure your batteries still have energy in them (especially if your power supplies are off continually, they will drain the batteries quickly), also verify that your Power Supply switch is set to the 1 or 2 battery position and not 'Off'. Like the other useres mentioned, wait 20 min for your CPU to come back from a full reset before trying to connect to it (for download, or diagnostic..etc) as it still booting and doing diagnostic checks and setups on itself. It sounds like you have been hunting this for a bit, I would recommend contacting your regional Siemens PCS 7 Technical Support hotline team which you can do so here, https://support.industry.siemens.com/my/ww/en/requests#createRequest Attach your PCS 7 version, CPU firmware version, and the problems you stated here. I believe they can provide you a tool that will capture information about your CPU in its failure state that go beyond the diagnostics (of which they will only be able to 'de-code'). Either they can give you a solution, or help setup an RMA of sorts. Wish I could be more help... |

Hello, There is also another topic about the CPU410 power on/off problem. Is this the same CPU? I asked in that topic if the batteries were shortcircuit before use. This must be done, to trigger the batteries and thus save your configuration data on the CPU. If this is not done, the CPU will reboot and trigger it's initialization phase (self check), which will take 15 minutes (already mentioned I believe). |
