Hi , We are also facing the same problem. Wehave CPU 417H as master redundantr system which is communicating to C240PN drive controller located at various distances 1) First RIO station at2km from CPUconnected via OLM 1300 ; This station has drive fed conveyor controlled by C240PN communicating via Profibus. 2) Second station at 2.7 Km from station i.e 4.7km from CPU connected via OLM 1300; This station also has drive fed conveyor controlled by C240PN communicating via Profibus. 3) Third station at 4 km from 2nd station i.e 9km from CPU connected via OLM 1300. This station also has drive fed conveyor controlled by C240PN communicating via Profibus.. our profibus speed is 1.5Mbps and we are facing the same problem of breakage of communication at random intervals. We are unable to find any solution. Hope anybody can suggest any solution to come out of it. Regards, JD Splitted from 6ES7416-2XN05-0AB0 communication problem faced. |

Hello JD_techmania I fully agree with J_Bell's advise,sporadically appearing network dropouts can be tough to troublehoot and have numerous causes (e.g. interference, poor connections, power supply issues etc. etc.). I suggestthat you get hold of aProfibus monitoring toolthat allows you to evalute the physical signal levels as well as monitoring of the data traffic and my choice for this would be Procentec's Profitrace 2. Disclaimer: Since the company I work for is also a partner of Procentec, this advise may appear to be biased, I can tell you though that I haven't come across a Profibus poblem that I couldn't solve with the help of this tool. I hope this helps and good luck |

Hello JD; If non-present slaves are rally your problem, you should look at the suggestions in Fritz' excellent post in the following thread: /tf/WW/en/Posts/42169 It indicated how to use SFC 12 to disable configured slaves and enable them at a later time; that way the CPU does not search for them for long periods and retries. Hope this helps, Daniel Chartier |
