Issue
Time schedules appear to be working backwards. Time schedule that controls occupancy of a LonWorks unit is not controlling properly. The unit is unoccupied instead of occupied.
Time schedule outputs need to be reversed to control I/NET points where 0 and 1 may not be off/on.
Environment
- Xenta Server
- Xenta 511, 527, 555, 701, 711, 721, 731, 913
- XBuilder
Cause
SNVT_Occupancy has the following values:
0 - Occupied
1 - UnOccupied
2 - ByPass
3 - StandBy
If the time object does not use the correct default and active values then the wrong value will be sent from the time schedule.
I/NET controls with the "first of the pair, second of the pair" which may require a 0 to be ON and a 1 to be OFF.
Resolution
Modify the Time Object for a SNVT_occupancy:
- In the Show Other Properties editor change the default value to 1 (Unoccupied).
- In each time event change the Active Value on the Other tab to 0 (Occupied).
- If edited offline, generate the project and send to the target.
