  • FIFO/LIFO Que Emptying without pop

    Hello,

    I have a FIFO/LIFO used to handle alarm ques. When there is an alarm I send a bit high to activate the push rung to populate the array. Buffer size is 256, storing 32 bit int. The que keeps emptying without it getting a pop. I have went as far as to block the pop run with an always open and still the que will empty on its own. I have a peek on a timer looking in but I don't think that should effect popping. Any thoughts? Does reading the tag associated to the pop data act as a pop message?

    Is the "One Shot" option checked in your FILI instruction?

        Need more info to try and help maybe a screenshot of the ladder? Maybe a screenshot of the dataview with status tags of the FILI instruction? What I have seems to work fine.
