  • Capture an event time

    I'm using a PE to detect a FIRST piece in a machine line and need to know the time it was detected. The PE will go low when the piece passes. Will a one-shot do the trick?

        Plenty. Falling edge contact. System time is stored in $Now (SDT0) as a full time structure or in $LocalTime (DST22) as a dword containing seconds since 1970.
