Hello crocodile; I remember studying this article from SMAR about Profibus-DP network troubleshooting. There are sections in it that discuss testing the connector with a multimeter; see the attached screenshot. http://www.smar.com/en/technical-article/tips-for-trouble-shooting-on-the-profibus-dp Hope this helps, Daniel Chartier Edit: for your second question, look at the diagram at the bottom of the article, showing the schematics of the termination résistors. I would say that if a channel is not working you might have trouble with the termination being properly powered up. Whenever a Profibus connecter is found defective, we discard it and try to have it replaced by the seller (if it a new one). D.C. |
