I'm setting up a PCS7 system and the physical layout is such that I would like to branch out in two different directions from my PLC. Can I branch my network out in such a way or does profibus require that I have all my slaves in series?

If this is the case, then all that is required is that the termination circuit (included is standard Profibus connectors) be activated on the first andlast nodes of the bus. If this does not reply to your query, please clarify. Hope this helps, Daniel Chartier Attachment Typical Profibus desig- master in middle.jpg (135 Downloads)
