Hello uzziel; First step, for the forum members, here is uzzyel's request in English: Hello all; I am new to this forum and I would like some help on some doubts I have on compatibility of projects in Step 7. I work in a factory in Mexico and it is the first time I work with these PLCs. We have a PG with Step 7 v5.4 SP1 installed, a few S7-300s, ET 200Ms and S7-400s. Recently we had a problem with a S7-400, the PC it was connected with showed communication failure. When I went to check the status of the PLC, all the LEDs were flashing. This had happened to us before, and we had to exchange the PLC. In this case I don’t know how we did the exchange because the old model was version 4.0 and the replacement is v.5.0. My question is if I simply remove the old CPU and replace it wit the new one in the Hardware Configurator, saving and compiling, can I load the project in the new CPU? I don’t know if it will be a problem as the project was created for v.4.0 hardware. Someone told me that Profibus addressing had changed and that I cannot find this CPU in the HWConfig editor, do I have to upgrade my version of Step 7? The installed CPU is model 6ES7 416-2FN05-0AB0 v.5.0, I can’t remember the part number of the old one. Thanks for your help. |

Hello, Basically this is the steps with replace the CPU. But you should check meanwhile profibus, mpi address... Let's say just compare visual the new configuration. It might be the same like previous. If you have troubles with this, is it possible to attach here your hardware configuration? Regards, Hristo Mihalev |

Hola uzzyel; Este foro es uno de los mejores que encontraras sobre los productos de automatizacion de Siemens, pero los idiomas usados son el ingles o el aleman (hay foros distinctos para cada idioma). Tendras que hacer esfuerzos para usar Ingles, como muchos aqui que no son de lengua inglesa maternal. Si tienes demasiado dificuldad en eso, mejor busar ayuda en varios muy buenos foros hispanicos, tal como: http://www.foro-industrial.com/foros/viewforum.php?f=8 http://www.automatas.org/foro/ The first thing I could suggest is to upgrade your version of Step 7. There is a free download of SP 5 for Step 7 v5.4 available from this site: This would give your hardware catalog access to all the latest model numbers of all modules. http://support.automation.siemens.com/WW/view/en/36184684 Just make sure you can handle the size of the download file through your Internet connection(745343 KB ). Hope this helps, Daniel Chartier |

Thankseverybody for your support, what I meant was that we have alreadyhad this problem with another S7-400, the plc seemed like it didn't have a project, because al leds were flashing, then, I upload a project, and i was doing it good, but when it was like half of project, suddenly all leds were flashing again andthe lost ofcommunication message appeared in the PG screen, well, the engineers decided to change it, the old one was version 4.0 and the new one was 5.0, now we had the same problem but, to solve the last one they called people from siemens and they didn't explain very good what they did, I would like to know if I can upload this project (originally for the hardware 4.0) to the new plc which is version 5.0, i can't attach the hardware configuration of the project, maybe next week, altough the problem will be solved by that time,I want to know solution for this problem, because I think that is kind of embarrassing to call siemen's people each time we have problems like this, if you need more information in order to help me tofigure outthis one please tell me thanks in advence best regards |

Dear uzzyel, I hope you have already solved your problem. Though i didn't see your tread earlier, i just want to share with you my thinking. There is another possibility to upload the program/project. S7-400 CPU has a FEPROM card. The previous programmer could have save the project/program into the flash card. So you can remove the flash card andinsert intothe new S7-400 CPU. From there, you can try to upload to your PG/laptop. Hope this helps! with regards, how come? |

Hallo Everyone (I know only English), I have encountered this problem several times.I managed to resolve this by following ways. 1. If CPU is not fitted properly on the S7-Rack (UR or UR2) then this problem can occur. (Remove the screws and fit it onceagain on the rack. see if any of the pin on the rack is broken/bend. 2. Upgrade the firmware of the CPU. Now-a-days its possible to upgrade the firmware online.(no need of extra EPROPM). 3. You can check if CPU is functioning properly by removing all other CPs from Rack. Keep only PS and CPU on Rack, do MRST and AS should go to RUN mode. 4. Also if some of the MAC addresses of CP cards may be CP1613 or CP443-1 are getting conflict(maybe no unique addresses used while configuration)then AS may encounter this failure. |
