FB_DALI103QueryEventFilter
The function block reads the event filter (see eventFilter) for the selected instance of the DALI control device.
Each bit of the input variable nEventFilter represents an event. If the bit is set, the associated event is enabled.
The meanings of the individual bits for the respective instance types can be found here:
Part 301 (push buttons) – Introduction
Part 302 (absolute input devices) - Introduction
Part 303 (occupancy sensors) - Introduction
Part 304 (light sensors) - Introduction
The output nEventFilter contains a valid value only if the function block was executed without errors (bError = FALSE).
The function block cannot be used when using the KL6811. |
Inputs
VAR_INPUT
bStart : BOOL;
nAddress : BYTE;
eAddressType : E_DALIAddressType := E_DALIAddressType.Short;
nInstanceAddress : BYTE := 0;
eInstanceAddressType : E_DALIInstanceAddressType := E_DALIInstanceAddressType.InstanceNumber;
eCommandPriority : E_DALICommandPriority := E_DALICommandPriority.MiddleLow;
END_VAR
Name | Type | Description |
---|---|---|
bStart | BOOL | Execution of the DALI commands is triggered via a positive edge at this input. |
nAddress | BYTE | Address of a DALI control gear or a DALI group. |
eAddressType | Defines whether the input nAddress contains a short address (0…63) or a group address (0…31). The input nAddress has no meaning if a broadcast or a broadcast to unaddressed devices (BroadcastUnaddr) has been selected. | |
nInstanceAddress | BYTE | Instance number within a DALI control device. A DALI control device can support multiple instance numbers. |
eInstanceAddressType | Defines the access mode to the desired instance within the DALI control device. | |
eCommandPriority | Priority (low, middle low, middle, middle high, high) with which the DALI commands are sent. |
The command priorities are supported by the KL6821 from the firmware version BD. |
Outputs
VAR_OUTPUT
bError : BOOL;
ipResultMessage : I_TcMessage;
bBusy : BOOL;
nEventFilter : DWORD;
END_VAR
Name | Type | Description |
---|---|---|
bError | BOOL | This output is switched to TRUE if an error occurs during the execution. Further information about the error can be queried via the variable ipResultMessage. The output is set to FALSE again as soon as bBusy switches to TRUE. |
ipResultMessage | I_TcMessage | Interface pointer (see error evaluation) that can be used to obtain detailed information about the processing of the function block (see runtime messages). The interface pointer is valid after bBusy has changed from TRUE to FALSE. |
bBusy | BOOL | The output is set as soon as execution of the DALI commands has commenced. It remains active until all DALI commands have been processed. |
nEventFilter | DWORD | Each bit represents a manufacturer-specific event that has been enabled or disabled. |
Properties
Name | Type | Access | Initial value | Description |
---|---|---|---|---|
ipDALICommunication | I_DALICommunication | Get,Set | 0 | Interface Pointer to the communication block (see Transfer of the reference to the communication block). |
