OUT	Determined by IN	The analog output value and status.
OUT_HI_ACT	None	Boolean value set True when the input is limited to the maximum value.
OUT_HI_LIM	Determined by IN	The maximum output value allowed.
OUT_LO_ACT	None	Boolean value set True when the input is limited to the minimum value.
OUT_LO_LIM	Determined by IN	The minimum output value allowed.
