FB_DALIV2xRemoveFromDeviceGroups
Removes the control unit from one or more groups.
A total of 32 groups are available to which a control unit can be assigned. Each bit of the variable nDeviceGroups corresponds to one of these groups. If the bit is set, the control unit is removed from the respective group. Bit 0 corresponds to group 0, bit 31 to group 31.
The function block FB_DALIV2xAddToDeviceGroups() can be used to assign a control unit to a group.
VAR_INPUT
bStart : BOOL;
nAddr : BYTE;
eAddrType : E_DALIV2AddrType := eDALIV2AddrTypeShort;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
nDeviceGroups : DWORD;
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.
nDeviceGroups: 32 bit variable where each bit represents the corresponding group from which the control unit is to be removed.
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;
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.
VAR_IN_OUT
stCommandBuffer : ST_DALIV2CommandBuffer;
stCommandBuffer: Reference to the internal structure for communication with the function block FB_KL6821Communication() (KL6821).
