Default

DEFAULT_SLOT_VALUE is used to get the standard idle values for a device (good values to send when it's doing nothing else). For example, on a moving light, this would be pan and tilt at 50%, intensity at zero, Color at open-white, gobo rotation off, etc.

Generally the manufacturer for a responder will know what values are good to use for defaults.

There's no standard way to get the current value. Generally, it's assumed that the RDM controller is also sending the Null-Start-Code DMX, so it should know what level it is sending.

Generally dimmers and relay don't need to support DEFAULT_SLOT_VALUE. It's really intended for more complicated devices where zero isn't necessarily what you want the console to send by default.
