DaveE Posted August 17, 2015 Report Share Posted August 17, 2015 Good Afternoon I have a new project that I have to start on, but I have one minor issue (Only 1 I hear you say) I am using a wenglor height sensor and need to measure the height of a stack of boxes coming down the conveyor. This wasnt an issue until the wonderful sales guy told me the rest of the information. Originally it was a flat bottom box going down the conveyor in stacks to a maximum of 10. That would have been easy with the reverse linearization that I was planning on using. Now it has just got a lot more complicated. The sales guy now tells me that along with the cardboard boxes, the customer wants to run plastic crates as well. The cardboard boxes have a solid bottom to them The plastic crates have a "mesh" bottom to them which means its going to be a now you see me, now you dont, as the values goes from the actual height to the zero level, sort of like a sine wave and the sensor goes through the mesh to the top of the conveyor. My question is there anyway to just read the maximum value of the MI and ignore the minimum value of the MI? I will be using a start trigger to know when to start reading the height sensor, and a timer to know how long to read the height sensor for, but I just dont know how to ignore what I dont want any suggestions welcome Quote Link to comment Share on other sites More sharing options...
