|
|
|
|
|
|
|
|
|
|
|
|
| occupancy arbitration logic). If the state is SW_NUL, the input is not |
|
|
|
|
|
|
|
|
|
|
|
|
| available because it is not bound, the input is no longer being updated by |
|
|
|
|
|
|
|
|
|

| the sender, or OC_BYPASS is no longer being called. This means that the |
|
|
|
|
|
|
|

|
|
|
|
| same as SW_OFF. If the state is SW_OFF or other and the value is don’t |
|
|
|
|
|
|
|
|
|
|
|
|
| care, the node should not bypass the time of day schedule. If the state is |
|
|
|
|
|
|
|
|
|
|
|
|
| SW_ON and the value is 0, then the node should not bypass the time of day |
|
|
|
|
|
|
|
|
|
|
|
|
| schedule. If the node receives this combination of state and value, then |
|
|
|
|
|
|
|
|
|
|
|
|
| state is set to SW_OFF. |
