Hello automali please have a look at chapter 5.10.2 of theOLM manual whichmay explain why you havethe problems. Put simple, if Profibus OLM's are used in a ring you need to adjust certain bus parameters (apart from the DIP switches which maybe another possible cause for your problem). Later Step7 versions (I believe as of V5.4 SP2 but don't quote me on that) allow you to specify "OLM ring" topology in the Options tab of your Profibus parameters, in which case Step 7 will automatically adjust the bus parameters for you. I hope this helps Cheers fritz |
