FB_DALIV2SwapShortAddress
The short addresses of two control gears can be swapped using the function block FB_DALIV2SwapShortAddress. However, this requires a free, unused short address to be available in the DALI line.
Inputs
VAR_INPUT
bStart : BOOL;
nShortAddress01 : BYTE;
nShortAddress02 : BYTE;
nFreeShortAddress : BYTE;
END_VAR
Name | Type | Description |
---|---|---|
bStart | BOOL | The function block is activated by a positive edge at this input. |
nShortAddress01 | BYTE | Short address of the first control gear (0 ... 63) |
nShortAddress02 | BYTE | Short address of the second control gear (0 ... 63) |
Inputs/outputs
VAR_IN_OUT
stCommandBuffer : ST_DALIV2CommandBuffer;
END_VAR
Name | Type | Description |
---|---|---|
stCommandBuffer | ST_DALIV2CommandBuffer | Reference to the internal structure for communication with FB_KL6811Communication (KL6811) or FB_KL6821Communication (KL6821). |
Outputs
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;
END_VAR
Name | Type | Description |
---|---|---|
bBusy | BOOL | When the function block is activated the output is set, and it remains active until execution of the command has been completed. |
bError | BOOL | 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 | UDINT | 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). |
