FB_DALIV2xSetEventFilter
This function block sets the event filter for the respective control unit instance.
Each bit in nEventFilter represents an event. If the bit is set, the associated event is enabled. The event is locked if the bit is not set.
The meaning of the individual bits can be found in the documentation of the respective control unit.
VAR_INPUT
bStart : BOOL;
nAddr : BYTE;
eAddrType : E_DALIV2AddrType := eDALIV2AddrTypeShort;
nInstAddr : BYTE := 0;
eInstAddrType : E_DALIV2InstAddrType := eDALIV2InstAddrTypeNumber;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
nEventFilter : DWORD := 0;
bStart: The function block is activated by a positive edge at this input.
nAddr: The address of a participating device or of a group.
eAddrType: Short address, group address or broadcast.
nInstAddr: Address of the instance within the DALI control unit.
eInstAddrType: Defines the access mode to the desired instance within the DALI control unit.
eCommandPriority: Priority (high, medium or low) with which the command is processed by the library.
nEventFilter: Each bit represents an event to be enabled or disabled.
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;
bBusy: When the function block is activated the output is set, and it remains active until execution of the command has been completed.
bError: 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: 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.
VAR_IN_OUT
stCommandBuffer : ST_DALIV2CommandBuffer;
stCommandBuffer: Reference to the internal structure for communication with the function block FB_KL6821Communication() (KL6821).
