FB_DALIV2VerifyShortAddress
If the short address in the control gear is equal to the parameter nShortAddress, the output bAnswer is set to TRUE.
Inputs
VAR_INPUT
bStart : BOOL;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
nShortAddress : 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. | |
nShortAddress | BYTE | Short address with which the own short address is to be compared. |
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;
bAnswer : BOOL;
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). |
bAnswer | BOOL | The parameter nShortAddress is the same as its own short address. |
Requirements
Development Environment | PLC library to include |
