programming Totolizer on Wincc V5.1/S7

[robert mooli]

Hullo people again , Now we have a project where we have to incorporate six weigh belt feeding system on an existing seimens s7 416-2DP plc , everything seem to be ok , but now how do one configure a totolizer on WINCC to know how much tonnage 3 feeders have fed downstream for a time ,they were started , theres AO , 4-20Ma from the feeders (3) to indicate the flow sum, we have got free AI on the analogue modules .THanks

robert,

To "know how much tonnage 3 feeders have fed downstream for a time ,they were started", you would take the three "flow sums" and scale the 4-20mA inputs to be equal to "tons", then add all three together to get the total tons that have been fed downstream.
