[[Image:filterwheel1a.png|The filter wheel web interface]]
The status (Initialised|At Ref|Centered|Moving) of the each wheel is displayed at the top, below the
wheel's name and binary-format ID.
The current position (1) of the wheel is displayed below this. The slot
number, and if available, filter name and color are also displayed.
Below this, the next required position (2) may be entered. There are then
buttons to move to the required position, or to initialize the wheel.
An "More..." (3) link allows the user to see which filters are installed
in each slot (if known), and also allows the user to reset the PLC.
