FB_DALIV2EnableDeviceType
This command must be sent every time prior to an application extended command. As a result, only those control gears that belong to the corresponding DEVICE TYPE respond. The command does not have to be used for device type 0. 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 incandescent lamps |
5 | Device for converting digital signals into DC signals |
6 | Device for light emitting diodes (LEDs) |
7 | Device for switching functions |
8 | Device for controlling the color/color temperature |
9 | Sequencer |
Inputs
VAR_INPUT
bStart : BOOL;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
nDeviceType : BYTE;
END_VARName | Type | Description |
|---|---|---|
bStart | BOOL | 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. | |
nDeviceType | BYTE | Identifier for the device type (see table above). |
Inputs/outputs
VAR_IN_OUT
stCommandBuffer : ST_DALIV2CommandBuffer;
END_VARName | 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_VARName | 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). |
Requirements
Development Environment | PLC library to include |
