FB_DALIV2xQueryRandomAddressM

VAR_INPUT

bStart            : BOOL;
nAddr             : BYTE;
eAddrType         : E_DALIV2AddrType := eDALIV2AddrTypeShort;
eCommandPriority  : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
eDataFrameType    : E_DALIV2DataFrameType := eDALIV2DataFrameType24Bit;

bStart: The function block is activated by a positive edge at this input.

nAddr: The address of a participating device or of a group.

eAddrType: Short address, group address or broadcast.

eCommandPriority: Priority (high, medium or low) with which the command is processed by the library.

eDataFrameType: Output format of the DALI command (eDALIV2DataFrameType24Bit or eDALIV2DataFrameTypeOsram).

VAR_OUTPUT

bBusy            : BOOL;
bError           : BOOL;
nErrorId         : UDINT;
nRandomAddressM  : BYTE;

bBusy: When the function block is activated the output is set, and it remains active until execution of the command has been completed.

bError: This output is switched to TRUE as soon as an error occurs during the execution of a command. The command-specific error code is contained in nErrorId. Is reset to FALSE by the execution of a command at the inputs.

nErrorId: Contains the command-specific error code of the most recently executed command. Is reset to 0 by the execution of a command at the inputs. See Error codes.

nRandomAddressM: The medium-order byte of the random address/long address.

VAR_IN_OUT

stCommandBuffer   : ST_DALIV2CommandBuffer;

stCommandBuffer: Reference to the internal structure for communication with the function block FB_KL6821Communication() (KL6821).
