FB_DALIV2QueryTestTiming

FB_DALIV2QueryTestTiming 1:

The function block FB_DALIV2QueryTestTiming reads the test times (intervals, duration until the next event, etc.) from the control gear. This takes place depending on the value applied at the nDTR input. The background to this is that the DALI basic command 242 “Query test timing” works together with the contents of the Data Transfer Register (DTR), which must be written to accordingly beforehand. The function block FB_DALIV2QueryTestTiming combines these two actions. The following data are read from the device, depending on the nDTR value:

nDTR	read value
0 (2#0000 0000)	If automatic test is activated: time until next function test (high-byte) in quarter hours If automatic test is not activated: MASK (255)
1 (2#0000 0001)	If automatic test is activated: time until next function test (low-byte) in quarter hours If automatic test is not activated: MASK (255)
2 (2#0000 0010)	If automatic test is activated: time until next duration test (high-byte) in quarter hours If automatic test is not activated: MASK (255)
3 (2#0000 0011)	If automatic test is activated: time until next duration test (low-byte) in quarter hours If automatic test is not activated: MASK (255)
4 (2#0000 0100)	If automatic test is activated: test interval of the function test in days If automatic test is not activated: MASK (255)
5 (2#0000 0101)	If automatic test is activated: test interval of the duration test in weeks If automatic test is not activated: MASK (255)
6 (2#0000 0110)	Test execution timeout in days (maximum execution period for one test). Applies only to the automatic test!
7 (2#0000 0111)	Lamp-on extension time after exiting from emergency operating mode, measured in 0.5-min steps

	This command belongs to the application extended commands for DALI emergency lighting. These only work if they are preceded by the Enable Device Type 1 command, which can be sent with the function block FB_DALIV2EnableDeviceType. The Enable Device Type 1 command is internally placed automatically before all application extended commands for DALI emergency lighting.

Inputs

VAR_INPUT
  bStart           : BOOL;
  nAddr            : BYTE;
  eAddrType        : E_DALIV2AddrType;
  eCommandPriority : E_DALIV2CommandPriority;
  nDTR             : BYTE;
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.
nDTR	BYTE	The corresponding values are read in accordance to this input, see above.

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;
  nValue   : 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).
nValue	BYTE	Result
