FB_DALIV2QueryOperatingMode

FB_DALIV2QueryOperatingMode 1:

Queries the value of OPERATING MODE.

FB_DALIV2QueryOperatingMode 2:

This command is one of the application extended commands for LED modules with DALI interface. These only work if they are preceded by the Enable Device Type 6 command, which can be sent with the function block FB_DALIV2EnableDeviceType(). From version 2.6.0 of the libraries TcDALIV2 and TcDALIV2AppExtCmds, however, the Enable Device Type 6 command is internally placed automatically before all application extended commands for LED modules with DALI interface.

VAR_INPUT

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

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.

eCommandPriority: Priority (high, medium or low) with which the command is processed by the library.

VAR_OUTPUT

bBusy         : BOOL;
bError        : BOOL;
nErrorId      : UDINT;
nOperatingMode: BYTE;

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.

nOperatingMode: Value of OPERATING MODE.

VAR_IN_OUT

stCommandBuffer   : ST_DALIV2CommandBuffer;

stCommandBuffer: Reference to the internal structure for communication with the function blocks FB_DALIV2Communication() (KL6811) or FB_KL6821Communication() (KL6821).
