1 This value is the last enumeration received. It can come from either the nviOccManCmd network variable or the operator dis-
play schedule override.
2 Null = any other value.
3 The variable nviOccSensor is used with the SCC profile only. Refer to the Null rows in this column for the DAC profile.
4 This value represents whether or not the bypass timer is at zero or not. When a bypass request is made, the timer is set to the
value specified in the Occupied Bypass Timer field, and it begins to count down. While it is counting down, the value is not
zero. When the count down is complete, the value is zero.
