junkyardgary Posted January 26, 2023 Report Posted January 26, 2023 I have been troubleshooting another engineers logic. There is a couple lines that have real world inputs, IE: I00100 and I00101. Each has it own rung, these inputs are POSCON and feed a reset coil each. One line works fine, one does not. I have verify the inputs are transitioning from off to on, but one reset works, and the other does not. The processor is a CPE-100. Is there a problem using real world inputs with the POSCON instruction? The results are very reliable, the same issue happens every cycle, never any variation. I'm just trying to make sense out of it before changing a "standard" logic program, without explanation. I am a hired gun engineer here for a few months. Don't want to make unnecessary waves. Quote
