FB_KL6821Config

Example

The function block is called in the same task as the function block FB_KL6821Communication().

The function block FB_KL6821Config() is linked to the process image of the KL6821. Once the configuration is complete, the function block FB_KL6821Communication() receives the process values of the KL6821. DALI commands cannot be sent during configuration.

VAR_INPUT

bConfigurate                  : BOOL := FALSE;
eCommandKBusWatchdog          : E_DALIV2ConfigurationCommands := eDALIV2CommandDoNothing;
eCommandDI1RisingEdge         : E_DALIV2ConfigurationCommands := eDALIV2CommandOff;
eCommandDI1FallingEdge        : E_DALIV2ConfigurationCommands := eDALIV2CommandDoNothing;
eCommandDI2RisingEdge         : E_DALIV2ConfigurationCommands := eDALIV2CommandRecallMaxLevel;
eCommandDI2FallingEdge        : E_DALIV2ConfigurationCommands := eDALIV2CommandDoNothing; 
ePowerSupplyMode              : E_DALIV2PowerSupplyMode := eDALIV2PowerSupplyModeOn;
nOptions                      : DWORD := 0;

bConfigurate: Configuration of the Bus Terminal is started by a positive edge at this input.

eCommandKBusWatchdog: Defines the DALI command that is sent as soon as the Bus Terminal is no longer addressed via the K-bus.

eCommandDI1RisingEdge: Defines the DALI command that is sent as soon as a rising edge is detected at input 1 of the Bus Terminal.

eCommandDI1FallingEdge: Defines the DALI command that is sent as soon as a falling edge is detected at input 1 of the Bus Terminal.

eCommandDI2RisingEdge: Defines the DALI command that is sent as soon as a rising edge is detected at input 2 of the Bus Terminal.

eCommandDI2FallingEdge: Defines the DALI command that is sent as soon as a falling edge is detected at input 2 of the Bus Terminal.

ePowerSupplyMode: Defines the operation mode of the internal DALI power supply.

nOptions: reserved for future expansions.

VAR_OUTPUT

bBusy                 : BOOL;
bError                : BOOL;
nErrorId              : UDINT;
nTerminalDescription  : WORD;
nFirmwareVersion      : WORD;
sDescription          : STRING;

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. Reactivating the function block via the bConfigurate input sets the output to FALSE again.

nErrorId: Contains the command-specific error code of the most recently executed command. It is reset to 0 by activating the function block again via the input bConfigurate. See Error codes.

nTerminalDescription: Contains the terminal designation (e.g. 6821). Corresponds to register 8 of the Bus Terminal.

nFirmwareVersion: Contains the firmware version. Corresponds to register 9 of the Bus Terminal.

sDescription: Terminal designation and firmware version as string (e.g. 'Terminal KL6821 / Firmware 2H').

VAR_IN_OUT

stInDataTerminal          : ST_KL6821InData;
stOutDataTerminal         : ST_KL6821OutData;
stInData                  : ST_KL6821InData;
stOutData                 : ST_KL6821OutData;

stInDataTerminal: Reference to the structure for communication with the KL6821.

stOutDataTerminal: Reference to the structure for communication with the KL6821.

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

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