FB_DALIV2SendDALICommand

FB_DALIV2SendDALICommand 1:

The function block FB_DALIV2SendDALICommand is used for the general sending of a DALI command, defined by command number and, if necessary, transfer parameters. Moreover, it is possible to set whether the command is sent twice in succession and whether to wait for a response. The latter can be used, for example, to realize a fast sequence of step-up commands.

Inputs

VAR_INPUT
  bStart                       : BOOL;
  nAddr                        : BYTE;
  eAddrType                    : E_DALIV2AddrType := eDALIV2AddrTypeShort;
  eCommandPriority             : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
  nCommand                     : INT := 0;
  nParameter                   : BYTE := 0;
  bWaitingForDALISlaveResponse : BOOL := FALSE;
  bRepeatCommand               : BOOL := FALSE;
  bSuppressResponseBuffer      : BOOL := FALSE;
  nDeviceType                  : BYTE := 0;
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	E_DALIV2AddrType	Short address, group address or broadcast
eCommandPriority	E_DALIV2CommandPriority	Priority (high, medium or low) with which the command is processed by the library.
nCommand	INT	Number of the DALI command to be sent
nParameter	BYTE	Parameter for the value transfer
bWaitingForDALISlaveResponse	BOOL	If FALSE there is no waiting for the response of the DALI control gear. Its application makes no sense in connection with any kind of query command.
bRepeatCommand	BOOL	Decides whether the command is to be sent twice in succession.
bSuppressResponseBuffer	BOOL	If TRUE, the internal software buffer is not filled with the response from function block FB_DALIV2Communication.
nDeviceType	BYTE	Identifier for the device type

Value	Description
0	Standard device
1	Device for emergency lighting.
2	Device for discharge lamps.
3	Device for low-voltage halogen lamps.
4	Device for dimming incandescent lamps.
5	Device for converting digital signals into DC signals.
6	Device for light emitting diodes (LEDs).

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;
  nResponseData : BYTE;
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).
nResponseData	BYTE	The value received from the DALI control gear, if a query command has been called.

Requirements

Development Environment	PLC library to include
TwinCAT from v3.1.4020.14	Tc2_DALI from v3.4.3.0
