FB_DALIV2SwapShortAddress
The short addresses of two ballasts can be swapped using this function block. In order to do this, however, it is necessary that a free, unused short address is present in the DALI line.
VAR_INPUT
bStart : BOOL;
nShortAddress01 : BYTE;
nShortAddress02 : BYTE;
nFreeShortAddress : BYTE;
bStart: The block is activated by a rising edge at this input.
nShortAddress01: Short address of the first ballast (0 – 63).
nShortAddress02: Short address of the second ballast (0 – 63).
nFreeShortAddress: Free short address (0 – 63).
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.
