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
STATUS (Page 106).
