FB_DALIV2QueryPowerOnLevel

FB_DALIV2QueryPowerOnLevel 1:

The function block FB_DALIV2QueryPowerOnLevel reads the variable POWER ON LEVEL (switch-on lamp power) from the control gear. The lamp switches itself to this power value immediately after the power is connected.

Inputs

VAR_INPUT
  bStart           : BOOL;
  nAddr            : BYTE;
  eAddrType        : E_DALIV2AddrType := eDALIV2AddrTypeShort;
  eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
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.

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;
  nPowerOnLevel : 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).
nPowerOnLevel	BYTE	Lamp power at switch-on (0 - 254)
