Description
FLICKER
BOOL
I, Q, M, D,
L or Con-
stant
Specify the type of identification process:
•
FLICKER = 0: Identify the device by DALI command IDENTIFY.
The identifying process is specified by manufacturer.
•
FLICKER = 1: Flicker the control gear to identify the device by
setting the level, only valid for control gears. After the identifica-
tion, the level of control gears is set to "MIN_LEVEL".
CANCEL
BOOL
I, Q, M, D,
L or Con-
stant
CANCEL = 1: Stop current identify procedure, and return an error.
CM_DALI InOut
"DALI_CT
RL"
The data block of DALI_CTRL specifies the CM 1xDALI which com-
municates with the current function block.
BUSY
Output
BOOL
I, Q, M, D,
L
Status parameter:
•
BUSY = 0: Processing of job is terminated.
•
BUSY = 1: Job is still being committed.
ACTIVE
BOOL
I, Q, M, D,
L
Status parameter:
•
ACTIVE = 0: Job is not yet started.
•
ACTIVE = 1: Job is being executed.
DONE
BOOL
I, Q, M, D,
L
Status parameter:
•
DONE = 0: Job is not yet started or still executing.
•
DONE = 1: Job is executed without errors.
ERROR
BOOL
I, Q, M, D,
L
Status parameter:
•
ERROR = 0: No error occurs.
•
ERROR = 1: Error occurs during processing.
STATUS
BYTE
I, Q, M, D,
L
When ERROR = 0, STATUS has
following three values:
•
16#00: Idle
•
16#01: Executing
•
16#7F: Completed
When ERROR = 1, STATUS
shows the detailed error code. For
the detailed meaning of each
error code, refer to Parameter
5.4.3
DALI_DEV_CHG_ADDR
Description
DALI_DEV_CHG_ADDR is used for changing the short address of one device. If the new
address is assigned to another device, the two devices exchange their short addresses.
This function block only changes the short address of the physical devices. The data in the
CM 1xDALI is not influenced by this short address changing (refer to data flow path 5
(Page 23)).
