Posted 17 Oct 2016 First, why does it need to be in structured text? Second, have you written up a list of the possible scenarios so you can begin programming? First step in writing a PLC program is to build a complete sequence of operation. Share this post Link to post Share on other sites

Posted 21 Oct 2016 There would be more than one solution to your programming requirement. The attached program printout is in ladder, but functions similar to your description. This program works as a simple first in, first out with no priority to a specific hopper. I don't program in structured text, so this is all I would have to offer. I hope this is helpful.
