Attributes with extra quality handling

PV

When the PVMode is Manual, then quality is UNCERTAIN. When PVMode is Auto, the quality is the same as the PVAuto attribute quality.

PVAuto

The quality is BAD if the object is offscan. Otherwise, the quality is the same as the input quality, either INITIALIZING, UNCERTAIN, or GOOD. The quality can also be UNCERTAIN if the input quality is GOOD, but the value of PVAuto is less than the minimum scaled range or greater than the maximum scaled range.

SP

If the AnalogDevice object is configured as an analog regulator, when the object goes onscan, the quality set to INITIALIZING. While the object is executing, if external data cannot be translated to appropriate data type, the quality is set to BAD. Otherwise, the quality is set to the quality of the external data. When the object goes offscan, the quality is set to BAD.
