Unsigned Value of Byte:

   0×01 = Zone sensor clear and motor stopped

   0×02 = Zone sensor clear, motor running,
          accepting from upstream zone

   0×04 = Zone sensor blocked, motor running,
          discharging to downstream zone

   0×05 = Zone sensor blocked and motor stopped

   0×06 = Busy (state during ConveyStop active
          mode)

The values 0xXX01 thru 0xXX06 are shown because these are the possible logical values used for inter-module communication. External networked devices (PLC or PC) monitoring these registers may; depending on their scan rate, not actually see each of these values change in sequence as a Carton is conveyed from zone to zone, even though the inter-module communications and ZPA is functioning normally.
