FB_DALIV2QueryOperatingMode
Queries the value of OPERATING MODE.
 | 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).
