Hello FIE Expert; Could you please elaborate on that 30 m cablelimit you are mentionning? It can't be for the interface module, Profibus-DP and Profinet both offer you longer connections. If it relates to the distace between the units and the motors, well, that's when distribued systems can come to helps, just bring additional units close to the motors you want to control. If the price is an issue, we have done similar conveyor controls using both As-i and Profibus-DP without problems. It does not have to be a single ET200pro cell used to control all elements of the conveyor system. About the issue of IP65-rated 24 v power supplies: the following Google page brought out many providers of such material; the first 2 hits were from Siemens Sitop group. http://www.google.ca/search?hl=en&q=24+VDC+power+supply+IP65&meta= Hope this helps, Daniel Chartier |
