DALI_ECG_QUERY_OPHOUR

Description
DALI_ECG_QUERY_OPHOUR is used for querying the operation hour of DALI control gear.
The operation hour accumulates when the control gear remains on for one hour. The
operation hour is stored in the CM 1xDALI (refer to data flow path 2 (Page 23)). If you
change short adresses of two control gears, the operating hours of these two control gears
are not be changed, you exchange the related operation hours of these two control gears by
using DALI_ECG_SET_OPHOUR (Page 59).
Before calling this function block, make sure that the control gear is configured by using
DALI_ECG_ADD (Page 67) or DALI_DEV_UPLOAD (Page 100).
When you query the operating hour of the control gear, the following occurs:
● If the control gear is not configured before, the error code "16#8D" is shown in the output
parameter of STATUS.
● If the control gear is configured, but the type of control gear is mismatched, the error code
"16#8B" is shown in the output parameter of STATUS.
