FB_DALI202QueryTestTiming

FB_DALI202QueryTestTiming 1:

Depending on the input eTestTiming, this function block reads out the settings for the function and duration test from the DALI control gear.

The eTestTiming input currently defines the following actions:

eTestTiming

Meaning

FunctionTestDelayTime

The value of the variable functionTestDelayTime is read.

DurationTestDelayTime

The value of the variable durationTestDelayTime is read.

FunctionTestInterval

The value of the variable functionTestInterval is read.

DurationTestInterval

The value of the variable durationTestInterval is read out.

TestExecutionTimeout

The value of the variable testExecutionTimeout is read.

ProlongTime

The value of the variable prolongTime is read.

FB_DALI202QueryTestTiming 2:

Prior to the DALI command QUERY TEST TIMING, the function block sends the DALI command ENABLE DEVICE TYPE 1, as is necessary for application extended commands (see also FB_DALI102EnableDeviceType).

FB_DALI202QueryTestTiming 3:

The function block changes the DTR0 of all connected DALI control gears.

The output nValue contains a valid value only if the function block was executed without errors (bError = FALSE).

FB_DALI202QueryTestTiming 4: Inputs

VAR_INPUT
  bStart            : BOOL;
  nAddress          : BYTE;
  eAddressType      : E_DALIAddressType := E_DALIAddressType.Short;
  eCommandPriority  : E_DALICommandPriority := E_DALICommandPriority.MiddleLow;
  eTestTiming       : E_DALITestTiming := E_DALITestTiming.TimeUntilNextFunctionTestMSB;
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

E_DALIAddressType

Defines whether the input nAddress contains a short address (0…63) or a group address (0…15). The input nAddress has no meaning if a broadcast or a broadcast to unaddressed devices (BroadcastUnaddr) has been selected.

eCommandPriority

E_DALICommandPriority

Priority (low, middle low, middle, middle high, high) with which the DALI commands are sent.

FB_DALI202QueryTestTiming 5:

eCommandPriority has no function with the KL6811. The DALI command priorities are supported by the KL6821 from the firmware version BD.

Name

Type

Description

eTestTiming

E_DALITestTiming

Defines the variable that the function block should read from the DALI control gear (see table above).

FB_DALI202QueryTestTiming 6: Outputs

VAR_OUTPUT
  bError                  : BOOL;
  ipResultMessage         : I_TcMessage;
  bBusy                   : BOOL;
  nValue                  : UINT;
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.

nValue

UINT

The value that was read out (see table above).
