Hello vipz; 1. as long as you repect the definition of the segment (for 1000 m you need to go down in transmission speed to 187,5 kB or less, and no more than 32 nodes in all) you will have no problem. If you are adding a 33rd station, especially a programming unit (monitoring uses up a lot of ressources on the bus) you might cause some loss of communications. So thisnk about inserting a repeater somewhere in your busline. 2. there is no standard in Profibus on the prosition of the nodes; a DP-master is simply another node 9configured and programmed differently than a slave) that can exist anywhere on the bus. 3. there is a lot (and I mean a lot) of information on Profibus-DP on this forum and on the web. Amongst these many documents, look up this one from Siemens (see the attached document) SIMATIC NET PROFIBUS Network Manual System Manual and downloadthese guidelinesfrom profibus.com http://www.profibus.com/nc/downloads/downloads/profibus-installation-guideline/display/ Hope this helsp, Daniel Chartier |
