FB_DALIV2QueryStatus
The STATUS INFORMATION variable is read by the ballast. The status information contains the eight most important items describing the status of a ballast. The significance of the individual bits is defined as follows:
Bit | Description |
|---|---|
0 | Status of the ballast. 0: OK. |
1 | Lamp failure. 0: OK. |
2 | Lamp power on. 0: OFF. |
3 | Limit value error. 0: the most recently requested lamp power was either between MIN LEVEL and MAX LEVEL or was OFF. |
4 | Fading completed: 0: fading finished. 1: fading active. |
5 | Reset status. 0: No. |
6 | Missing short address. 0: No. |
7 | Power supply fault. 0: No, A reset or a lamp power control command has been received since the most recent power up. |
VAR_INPUT
bStart : BOOL;
nAddr : BYTE;
eAddrType : E_DALIV2AddrType := eDALIV2AddrTypeShort;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
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.
eCommandPriority: The priority (high, middle, low) this command has when executed by the library.
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;
nStatus : BYTE;
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.
nStatus: Status information (see table above).
VAR_IN_OUT
stCommandBuffer : ST_DALIV2CommandBuffer;
stCommandBuffer: A reference to the structure for communication with the FB_DALIV2Communication() (KL6811) or FB_KL6821Communication() (KL6821) block.
