A CTIVITY COUNTER
Number of Failures—This statistic reports the number of failures that occurred at the
conveyor.
The value of this statistic is the last value of the conveyor variable Conveyor
Name_NumFailures.
Number of Scheduled Stops—This statistic reports the number of scheduled stops that
occurred at the conveyor.
The value of this statistic is the last value of the conveyor variable Conveyor
Name_NumScheduledStops.
Number of Blockages—This statistic reports the number of blockages that occurred at the
conveyor (i.e., number of times speed factor equaled 0 for reason other than failure or
scheduled stop).
P
ERFORMANCE
Average Units On When Speed Factor Equaled 0—This statistic reports the average
number of units on the conveyor during the periods when the speed factor of the conveyor
was zero (i.e., the conveyor was failed or in a scheduled stop, or the conveyor was
blocked).
The value of this statistic is the time-weighted average of the conveyor variable Conveyor
Name_UnitsInside over the time the conveyor had a speed factor of zero.
Average Units Traveling—This statistic reports the average number of units traveling on
the conveyor when the conveyor was running (i.e., had a speed factor greater than zero).
The value of this statistic is the time-weighted average of the conveyor variable Conveyor
Name_UnitsTraveling over the time the conveyor had a speed factor greater than zero.
Average Units Accumulated—This statistic reports the average number of units accumu-
lated on the conveyor when the conveyor was running (i.e., had a speed factor greater than
zero).
The value of this statistic is the time-weighted average of the conveyor variable Conveyor
Name_UnitsAccumulated over the time the conveyor had a speed factor greater than zero.
Average Input Rate—This statistic reports the average input rate of units onto the
conveyor when the conveyor was running (i.e., had a speed factor greater than zero).
The value of this statistic is the time-weighted average of the conveyor variable Conveyor
Name_InputRate over the time the conveyor had a speed factor greater than zero.
Average Good Output Rate—This statistic reports the average good output rate of units off
the conveyor when the conveyor was running (i.e., had a speed factor greater than zero).
