FB_DALIV2WriteMemoryLocation

The value nValue is written in the memory bank of the control gear. The exact memory bank is specified by nMemoryBank and the address within the memory bank by nOffset.
![]() | This command can only be executed by DALI devices that comply with the IEC 62386 standard. |
Inputs

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. | |
nMemoryBank | BYTE | The memory bank to be accessed. |
nOffset | BYTE | The address within the memory bank to be accessed. |
nValue | BYTE | Value to be written to the memory bank of the control gear. |
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;
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). |
Requirements
