Fanuc PNS Number Mirror sending wrong number

  • Hey Gang,

    So when the PLC calls PNS0001, the UOP 11-18 reflects the PNS Number. My Issue is that if a programmer goes to the left screen while running and selects another PNS, eg PNS0050 for viewing purposes, the UOP now sends a 50, even though PNS0050 is not technically running. This is messing up our PLC because they use this number at multiple stages in there program. See below screen shot for reference.

    I look forward to your answers!



  • I recommend the PLC guys add logic to record the ACK when the production start bit (or something similar) goes high. A group output could be sent from the robot to avoid looking for a consistent ACK and to monitor sequence progression.
