FB_DALIV2Initialise
The addressing of the control gears is started with this command. The addressing has to be halted again with the FB_DALIV2Terminate() function block. The maximum duration is limited to 15 minutes. Each control gear ends the addressing automatically after 15 minutes had elapsed. The reaction of the control gears that receive this command depends on the parameter nParameter:
Value (binary) | Description |
|---|---|
0000 0000 | All control gears react. |
0AAA AAA1 | Control gears with the address AAA AAA react. |
1111 1111 | Control gears with no short address react. |
VAR_INPUT
bStart : BOOL;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
nParameter : BYTE;
bStart: The function block is activated by a positive edge at this input.
eCommandPriority: Priority (high, medium or low) with which the command is processed by the library (see E_DALIV2CommandPriority).
nParameter: Specifies which ballasts should react to this command (see table above).
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;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)
VAR_IN_OUT
stCommandBuffer : ST_DALIV2CommandBuffer;stCommandBuffer: Reference to the internal structure for communication with the function block FB_KL6811Communication() (KL6811) or FB_KL6821Communication() (KL6821).
