Hello all. I have a 5069-L306ERMS2 that is interfaced with an ABB IRC palletizing robot. I am having trouble metering cases to the pick point (controlled by PLC) when it involves a single case. What is happening is, the robot tells the PLC how many cases it requires for each pick. For cases of 2 or more, there is no issue. When it is a single case, the PLC register doesn't update fast enough and the conveyor allows an extra case through. All attempts I have made so far haven't worked because it throws a wrench into the sequencers. All of the tasks are scanned continuously, 500mS. I am thinking I should create a small routine that will update this register more predictably and quicker. What I can't decide is, should I make this event triggered (as soon as the robot sends), or periodic. I would sure appreciate some feedback on this. Thx
