DALI_ECG_STATUS_CHECK
Description
DALI_ECG_STATUS_CHECK
is used for checking the status of control gears. For the
detailed status bits description, refer to BASIC_STATUS and EXT_STATUS in
DALI_ECG_STATUS (Page 53).
You can set the status mask of all the control gears, compare with the actual status that is
stored in the CM 1xDALI, and then return the matching result. The function block checks the
status information which is saved in the CM 1xDALI (refer to data flow path 2 (Page 23)).
The CM 1xDALI queries the actual device status in the "Background detection period" which
is set in the Module Parameters (Page 21).
For example, for the control gear whose short address is 5, if you want to monitor whether
the bit 1 of BASIC_STATUS in
DALI_ECG_STATUS
(Page 53) set to 1, you can set input
EXT_STATUS to 0 and set STATUS_MASK[5] to 16#02.
