FB_DALIV2QueryGroups
The function block FB_DALIV2QueryGroups reads the variables GROUP 0-7 and GROUP 8-15 from the control gear and links them to a 16-bit value. Each bit represents one group. Bit 0 represents group 0, while bit 15 represents group 15. If the bit is set, the control gear belongs to the corresponding group.
Inputs
VAR_INPUT
bStart : BOOL;
nAddr : BYTE;
eAddrType : E_DALIV2AddrType := eDALIV2AddrTypeShort;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
END_VAR
Name | Type | Description |
---|---|---|
bStart | BOOL | The function block is activated by a positive edge at this input. |
nAddr | BYTE | The address of a device or of a group |
eAddrType | Short address, group address or broadcast | |
eCommandPriority | Priority (high, medium or low) with which the command is processed by the library. |
Inputs/outputs
VAR_IN_OUT
stCommandBuffer : ST_DALIV2CommandBuffer;
END_VAR
Name | 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;
nGroups : WORD;
END_VAR
Name | 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). |
nGroups | WORD | Group assignment |
