FB_DALIV2SetShortAddress
One or more ballasts receive a (new) short address with the aid of this block. Valid short addresses lie in the range between 0 and 63. If 255 is specified as the short address, the ballast's short address is deleted.
If you want to give a short address to a device that does not yet have one, you must transmit the command as a broadcast (eAddrType = eDALIV2AddrTypeBroadcast). This gives all the ballasts that are connected to the DALI terminal the short address nAddr. This includes the ballasts that did not so far have a short address.
VAR_INPUT
bStart : BOOL;
nAddr : BYTE;
eAddrType : E_DALIV2AddrType := eDALIV2AddrTypeShort;
nNewShortAddress : BYTE;
bStart: The block is activated by a rising edge at this input.
nAddr: The address of a participating device or of a group.
eAddrType: Short address, group address or broadcast.
nNewShortAddress: New short address (0-15) or mask (255).
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;
bBusy: When the 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 if 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 an instruction at the inputs.
nErrorId: Contains the command-specific error code of the most recently executed command. Is reset to 0 by the execution of an instruction at the inputs. See Error codes.
VAR_IN_OUT
stCommandBuffer : ST_DALIV2CommandBuffer;
stCommandBuffer: A reference to the structure for communication with the FB_DALIV2Communication() (KL6811) or FB_KL6821Communication() (KL6821) block.
