Issue
BACnet bCX schedules cannot be edited without an error.
Product Line
Andover Continuum
Environment
Continuun bCX4040 Schedule Firmare v4.500082
Cause
Following an upgrade to firmware v4.500082 the Schedule end date year 2038 now enforced and schedule cannot be modified if the end (effective) date is beyond this
Resolution
For all schedules newly created or otherwise, the end (effective) date needs to be set to 2038 or earlier see Script Programs in Continuum compared to StruxureWare Building Operation and using floats (32 bits) ...
If the date is set after 2038 then an error is seen when trying to edit the schedule
"An error code was returned from a BACnet operation, but the reason could not be determined."
Creating a new schedule with a date > 2038 can also give the error:
" Error setting attribute 'DeviceID' An error code was returned from s BACnet operation , but the reason could not be determined "
Defect was corrected in v4.500083
