FB_DALIV2QueryDeviceType
The device type (DEVICE TYPE) is read from the ballast. The following device types are defined according to the IEC 62386 standard:
Value | Description |
|---|---|
0 | Standard device |
1 | Device for emergency lighting. |
2 | Device for discharge lamps. |
3 | Device for low-voltage halogen lamps. |
4 | Device for dimming bulbs. |
5 | Device for converting digital signals into DC signals. |
6 | Device for light emitting diodes (LEDs). |
7 | Switching function. |
8 | Device for colour/colour temperature control. |
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;
nDeviceType : 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.
nDeviceType: Identifier for the device type (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.
