FB_DMXGetProductDetailIdList
This function block queries the categories to which the DMX device belongs.
RDM defines different device categories. Each DMX device can be assigned to up to 6 categories. The assignment is done by the device manufacturer and cannot be changed via RDM.
VAR_INPUT

byPortId : BYTE;
dwOptions : DWORD := 0;
bStart: The command is started by a positive edge at this input.
wDestinationManufacturerId: Unique manufacturer ID of the DMX device.
dwDestinationDeviceId: Unique device ID of the DMX device.

bBusy: When the 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 udiErrorId. Only valid if bBusy is FALSE.
udiErrorId: Contains the command-specific error code of the most recently executed command. Only valid if bBusy is FALSE. See Error codes.
arrProductDetails: Contains the list with up to 6 device categories.
