Parameter
Declaration Data type Memory
area
Description
QUERY
Input
BOOL
I, Q, M, D,
L or Con-
stant
Query the address information upon a rising edge.
DEV_TYPE
USInt
I, Q, M, D,
L or Con-
stant
Select the device type:
•
1: Control gear
•
2: Input device (Sensor)
DET_ALL
BOOL
I, Q, M, D,
L or Con-
stant
•
DET_ALL = 0: Query the address information which is saved
directly in the CM 1xDALI.
•
DET_ALL = 1: Detect all devices on the bus and then return the
latest address information.
CANCEL
BOOL
I, Q, M, D,
L or Con-
stant
CANCEL = 1: Stop the scanning/querying procedure, and return an
error.
CM_DALI
InOut
"DALI_CT
RL"
The data block of DALI_CTRL specifies the CM 1xDALI which
communicates 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 four values:
•
16#00: Idle
•
16#01 to 16#40: Detecting
the status from DALI devices.
•
16#41: Querying the infor-
mation from CM 1xDALI.
•
16#7F: Completed
When ERROR = 1, STATUS
shows the detailed error code.
For the detailed meaning of each
error code, refer to Parameter
